Fennel: A Multitasking Herb

by Peggy Riccio

Fennel in bloomI grow fennel, Foeniculum vulgare, in my Virginia garden for many reasons. As an accent in the garden, fennel grows easily from seed to a few feet tall. Sometimes, they are erect and sometimes they bend from the weight to weave among the perennials and shrubs. Their tubular stems mingle with the pumpkin vines on the ground or rest on top of the chrysanthemum shrubs, while their green, fern-like foliage peaks through the zinnias.

Throughout the summer, I can harvest the foliage for use in the kitchen. The leaves have an anise flavor and are good for flavoring fish and chicken dishes and root vegetables. Snips of the foliage can be sprinkled on salads, soup, eggs, and tuna salad sandwiches. 

In the summer, the fennel blooms with large, starburst-like structures, comprising many small yellow flowers. These attract beneficial insects and pollinators, which are good for the rest of my garden. Sometimes, I clip the flower heads for floral arrangements, but I always let some flowers go to seed. 

Fennel as filler in the gardenIn the fall, I clip the seed heads and put them in a paper bag. I save some seeds for sowing next year and some for the kitchen. The seeds have medicinal qualities (the foliage does not) and are often served at the end of the meal in restaurants to help with digestion and to freshen the breath. Eating the seeds or making a tea from the seeds can relieve flatulence, bloating, gas, indigestion, cramps, and muscle spasms. Fennel seeds are also called “meeting seeds,” because when the Puritans had long church sermons, they chewed on the seeds to suppress hunger and fatigue.

Fennel seedsIn the kitchen, seed can be used whole or ground or toasted in a dry frying pan. They can be used as a spice for baking sweets, bread, and crackers, or in sausage or herbal vinegars and in pickling. The seeds have the same anise flavor but are so sweet, they taste like they are sugar-coated. For me, it is like eating small candies, especially tasty after drinking coffee. 

I grow fennel for the caterpillar form of the black swallowtail butterflies. The caterpillars love to eat the foliage, and it makes me happy to grow food for them and to support the butterfly population.

Sometimes the fennel comes back the next year, but it really depends on the winter. I have heard that, in warmer climates, it gets out of control, but in my zone 7 garden, it has not been an issue. After a hard freeze, when I am cleaning up the garden, I cut back the old fennel stalks revealing new foliage at the base. In December, the new foliage is just as lush and green, providing me with more fennel for my recipes, as well as a nice garnish for holiday meals. 

Fennel in DecemberFennel is easy to grow from seed and should be sowed directly in the garden. The plants have a tap root and do not like to be transplanted. The plants prefer full sun but can tolerate some shade, and they need well-drained soil. Treat them like summer annuals and sow seeds every year. 

I should point out that there are two types of fennel: Foeniculum vulgare, which is the leafy one I grow, and Foeniculum vulgare var. dulce, which is the bulbing type. I have grown the bulbing type before but not for the accents it provides in the garden bed. The bulbing type is a shorter plant with a bulbous base, so it is harvested for the bulb before it flowers and sets seed. The bulb is often sliced fresh for salads or cooked with fish and vegetables. One could consider the bronze fennel a third type; it grows like the leafy fennel, only it is a dark bronze color, not bright green. Bronze fennel also can be used in the kitchen.

 

In the kitchen, use the foliage for:

  • green salads
  • fruit salad (nectarine/apricot)
  • egg dishes
  • soups and chowders
  • chicken salad or tuna salad
  • dips and cream sauces
  • yeast breads
  • fish (put a fish filet on bed of leaves and broil, or mix leaves with butter and drizzle over the fish)
  • vegetables such as root vegetables, peas, and potatoes
  • combine with parsley, chervil, and thyme, or make a fennel, parsley, thyme, and lemon juice rub for white fish

Seeds can be used for:

  • fish soup/stock
  • cucumber salads
  • soft cheeses
  • bread/biscuits/crackers
  • sausage mixtures and pork dishes
  • pickling vegetables
  • marinades for meat
  • bean, couscous, lentil, or bulgur wheat dishes
  • potato salad
  • dry rubs or spice blends/powders

A True Double Mint – Herb of the Month

By Maryann Readal

Red-stemmed apple mint leaves and flowersMentha x gracilis ‘Madalene Hill’ (double mint) is The Herb Society of America’s Herb of the Month for July. It is a fitting herb to be singled out for attention by The Herb Society because Madalene Hill was an HSA President,1986-1988. Madalene was considered to be the Grande Dame of Herbs in the United States and received many awards and accolades for her work with herbs. She passed away in 2009 at the age of 95.

Madalene broadened the cultivation and use of double mint. Discovered by Hill in Virginia, she began growing it in the 1950s at her legendary Hilltop Herb Farm near Houston, TX. Madalene described this mint as rare, “a handsome plant and a rare jewel” (Hill, 1987). Madalene is credited with either introducing or discovering a total of seven herbs (Lindner, 2009). Two of these herbs, one of them being double mint, were named after her.

Photo of Madalene Hill, past president of The Herb Society of AmericaDouble mint is the only mint that has both peppermint and spearmint oils, which gives it a very unique flavor and pleasant fragrance. This mint is also called red-stemmed apple mint. It is a hybrid between Mentha arvensis (wild mint) and Mentha spicata (spearmint). Past Honorary President of The Herb Society and herself a noted herbalist, Susan Belsinger remarked  that double mint “combines the sweetness of spearmint and the coolness of peppermint, and so its use extends beyond desserts and is especially good in both alcoholic and non-alcoholic drinks” (Belsinger, 2016).

Like all mints, double mint is very easy to grow but does need to be contained. It will fade away at the end of the growing season but comes back in the spring. It will grow in sun or part shade. Double mint’s smooth, pointed leaves, upright growth, and dark red stems make it a standout in the garden. The white to pale violet flowers, too, are noteworthy for a mint. It is great in fruit salads, teas, or fruit pies. Use it as a garnish for iced tea. It is good tossed with peas or beans. It is also used in Vietnamese cuisine. Though it is an aphid and rodent deterrent, gardeners will find it to be a welcome source of nectar for pollinators.

Photo of Wrigley's Doublemint gumYou may wonder if there is any connection between Wrigley’s Doublemint® gum and the double mint herb. The exact ingredients of the gum are a Wrigley’s trade secret. However, the company does disclose that the main ingredient of the gum is peppermint; and on its packaging, it displays two peppermint leaves, side by side. So, I don’t believe there is a connection between the double mint herb, Mentha x gracilis ‘Madalene Hill,’ and the Doublemint® gum, other than they both contain mint.

Basil – The King of Herbs

By Maryann Readal

Image of basil leavesBasil, Ocimum basilicum, still reigns today as the King of Herbs. Its royalty was established by the Greeks, when they gave the herb its name based on the Greek word basilikon, meaning “king.” Alexander the Great is said to have brought basil to the Greeks. According to legend, St. Helena, the Emperor Constantine’s mother, followed a trail of basil leading to the remains of Jesus’ cross (Lum, 2020). Since that time, basil has been considered a holy herb in Greece. Basil is used in the Greek Orthodox Church for sprinkling holy water, while some Greeks bring their basil to church to be blessed and then hang the sprigs in their home for health and prosperity (MyParea, n.d.). However, on the isle of Crete, basil somehow gained a bad reputation and was thought to be a symbol of the devil. There seems to be a thread of bad history associated with basil since early times.

Hindu man worshiping tulsi plantAlthough named by the Greeks, basil originated in India 5,000 years ago. In India today, the herb is considered a sacred herb. Holy basil, Ocimum tenuiflorum (also known as tulsi), is considered to be the manifestation of the goddess Tulasi, wife of Krishna. It is thought to have great spiritual and healing powers. According to legend, only one leaf of tulsi can outweigh Vishnu’s power. Every devout Hindu home will have a special place for a tulsi plant. It is believed that the creator god, Brahma, resides in its stems and branches, the river Ganges flows through the plant’s roots, the deities live in its leaves, and the most sacred of Hindu religious texts are in the top of holy basil’s branches (Simoons, 1998). Nurturing a tulsi plant ensures that a person’s sins will be forgiven and everlasting peace and joy will be had. (Simoons, 1998). The dried stems of old holy basil plants are used to make beads for Hindu meditation beads. Twentieth-century herbalist Maude Grieve said, “Every good Hindu goes to his rest with a basil leaf on his breast. This is his passport to heaven. It is indeed considered a powerful herb” (Grieve, 1931). 

Image of Egyptian embalmingFrom India, basil spread to Egypt, where the herb was used for embalming and has been found buried with the pharaohs. The herb then moved on to Rome and southern Europe, where the Romans fell in love with it. In Italy, basil was considered a sign of love. If young girls were seeking a suitor, they would place a pot of basil on their windowsill. If a potential suitor showed up with a sprig of basil, the girl would love him forever. 

Ocimum spp (16)Italy became the home of pesto, which basil has made famous. “Pesto was created by the people of Genoa to highlight the flavor of their famous basil. Using a mortar and pestle, they combined simple ingredients to make one of the world’s most famous pasta sauces” (Blackman, 2010). The simple sauce contains only basil, pine nuts, olive oil, garlic, and parmigiano-reggiano cheese. Pesto is still a very popular sauce for pasta or crackers, especially in the summer, when fresh basil is plentiful.

During the Middle Ages, they believed that in order to get basil to grow, one had to curse and scream while planting the seed. This is the origin of the French verb semer le basilic (sowing basil), which means “to rant.” It was also thought that if you smelled basil too much, scorpions would enter your brain. Today, the French call basil l’herbe royale, “the royal herb,” and pots of it are found in outdoor restaurants, not to deter scorpions but to deter mosquitoes. Fresh basil leaves are used to make pistou, the French version of pesto.

Image of sign at garden center apologizing for not carrying basil due to downy mildewBasil, a sun-loving member of the mint family, is an annual herb that thrives in summer heat. In fact, it will languish if planted in the garden before temperatures reach a consistent 70 plus degrees. Frequent harvesting of the leaves before flowers appear prolongs its growing season. It can be propagated by seed or cuttings. However, it is very susceptible to downy mildew, which researchers are constantly trying to overcome by breeding more disease-resistant varieties. The new gene editing CRISPR technology may show a promising solution to this problem (Riccio, 2022).

There are more than 100 varieties of basil and counting! Some basils are grown as ornamental plants because of their beautiful blooms. In fact, the Chinese name for basil translates to “nine-level pagoda,” which is a good description of its blooming stalk. African blue basil and wild magic basil are two examples of basils with nice blooms that I have found are bee magnets during the summer. If you are interested in attracting pollinators, your garden should certainly have these basils. Cardinal basil, which shows off its large burgundy flower clusters in late summer, is spectacular in the summer garden. It can also be used as a culinary basil. Lemon basil and ‘Mrs. Burns’ lemon basil, both having a lemon scent, are perfect for adding to lemonade, fruit salad, or ice cream. Add cinnamon basil to cinnamon flavored desserts. The showy leaves of purple ruffles basil, O. basilicum ‘Purple Ruffles’, make a nice contrast among other plants in the summer garden. When cooking with basil, it should be added at the end of cooking.

Varieties of basilBasil is not usually considered a medicinal herb, but it was used medicinally in the time of Hippocrates who prescribed it as a tonic for the heart and to treat vomiting and constipation. Pliny the Elder commented that it was good for lethargy and fainting spells, headaches, flatulence, and other digestive issues (Pliny, 1855). China and India have a long history of using basil as a medicinal herb as well.

 Basil does contain a healthy amount of vitamins A, C, and K and has antioxidant and antibacterial properties, which helps fight disease. Studies show that it can help reduce blood clots by making the blood less “sticky.” Animal studies suggest that it might help slow the growth rate of some types of cancer (Todd, 2015).

A plate of brownies with cinnamon basilSo, do enjoy fresh basil this summer. Remember to dry some for the winter, freeze the leaves, or combine chopped leaves with water and freeze in an ice cube tray for later use. However, you should take careful consideration before putting basil on your windowsill lest you attract an unwanted suitor.

Basil is The Herb Society’s Herb of the Month for June.

Wines from the Gardens and Fields of Scotland

By Catherine MacLennan

(This article was originally published in The Herb Society of America’s annual journal, The Herbarist, 41(1975): 37-40. Almost 50 years later, Mrs. MacLennan’s narrative still evokes vivid images of foraging for edible plant material on her family’s property in Scotland.)

West Highlands ScotlandVisitors to the West Highlands admire so much our woods and mountains, especially when the heather spreads its bright purple mantle of flowers, but how many ever stop to think of the numerous delicious wines which can be made from our shrubs and trees, their flowers, their berries and leaves.

Somewhere beside every West Highland croft or farmhouse in olden times, there grew—and may still be found growing—the Elder tree, called in Lowland Scots the Boor tree. Another name given to it—‘Buttery wood tree’—always causes argument. Some writers maintain it refers to the soft white inner pith of the young wood, others that it springs from one of its many uses.

On farms and crofts there used always to be a small stone-built dairy or milk house, where milk was set in flat pans and where cream was kept for churning. During summer small branchlets of Elder wood were kept in the dairy, as these banished flies and kept milk and cream fresh and sweet. Hence ‘Buttery wood.’

Whatever the name, the Elderflower produces one of the best of our home-made wines, light pale gold or goldy green, the home-made wine most nearly resembling Champagne. The Elder berries also make a delicious wine resembling Port when properly matured. Both these wines are health giving; an excellent stimulant at all times. The Elder flower buds were also used as a pickle to be served with cold meats.

Gooseberry Jelly flavoured with Elderflowers is a delicious preserve. Put a fully open spray of Elderflowers in a muslin bag and add the bag to the jelly during the final five minutes of cooking. Beauty aids, creams, toilet water and salves were all made from Elderflowers. As well as beautifying, it freshened and rejuvenated even the most dull and tired skin.

Another very common tree flowering in early summer is the Hawthorn or Mayflower. Its creamy blossoms are very fragrant and scent the air around it. The wine made from these blossoms is light, pleasant and has a delicate vanilla bouquet. A flavouring essence may also be made with Hawthorn blossom by using one pound of flowers to three pounds of powdered sugar. Layers of blossom with layers of sugar alternately are placed in a stone jar until all is used. Cover the jar closely and put in a cool cellar. (West Highland people with no suitable cellar used to find the milk house ideal.) Leave for full 24 hours, then remove to where the sun shines hot on the jar. After 48 hours strain this delicious essence into a bottle and stopper carefully.

Later, the Hawthorn berries make what I consider a wine even more exotic, when well matured, than that from the blossoms. It has a most unusual bouquet, smooth, rich and mellow.

Gorse flowersA shrub, usually thought of as a weed, which grows in the West Highlands by roadsides, hillside and lochside, and never seems to be out of flower, is the Gorse, Furze or Whin. It is so prickly that no animal will eat it, but its golden yellow flowers make a rich, rather heavy-bodied wine which is also very intoxicating. It must be given at least a year to mature and is worth waiting for. Its flavour is most unusual, a hint of almond with a touch of scent of the flowers.

Of all the wines I have made—and there are few which I have not made—Birch wine was always my favourite as regards making. Not my favourite wine, Elderflower is that, but I loved tapping the Birch trees to draw off the sap, searching the moss wood on a warm spring day for the most suitable tree, and making sure it was not a tree which already had been tapped the previous year or the year before that.

Betula pendula (silver birch) barkIt was like stepping back in time one century. Birch wine was a favourite wine of Queen Victoria and Prince Albert and throughout the years of her long reign large quantities had to be made at Balmoral every year. The time for tapping the Birch trees is when the leaf buds are swollen ready to open, usually early March. Having decided on the trees, you then get pieces of young Elder wood about four inches long, and scrape out the soft white pithy core leaving a hollow tube. Next take a brace with a bit, and bore a hole in the trunk of the Birch tree 18 inches from the ground, to allow the hollow posset of Elder wood to fit in firmly. When boring the Birch tree, as soon as the clear sap shows, stop, fit the posset and fix a clean, dry, sterilized bottle under the posset. The sap runs freely into the bottle, and whenever the bottle is full it must be securely corked. As many trees as possible should be tapped each day to give at least one gallon of sap, which is the best quantity to make at a time. The sap is clear and sparkling. If any hint of colour shows in the sap drawn off, discard it. One thing to remember, if the leaf buds have opened do not tap the tree; the sap will be slow to run as well as unsuitable for wine. It is certainly fascinating and challenging, waiting for just the right moment. When the possets are removed from the Birch trees, carefully fill up the holes with pieces of wood or resin and seal over with any form of wax to exclude all airborne diseases.

Tapping birch treeThe wine is made by boiling one gallon of sap with three and a half pounds of best sugar and the rind and juice of two lemons for about one hour. Strain into a jug or basin large enough to hold this quantity. When tepid add yeast, leave covered for four days, when the ferment will have caused a heavy scum to rise which must be carefully removed. Strain into a storage jar fitted with fermentation trap. In a month to six weeks the wine will have cleared. Decant into another storage jar and leave for one year. It is the home-made wine most nearly like Vodka and was a favourite in Scandinavian countries and Russia.

Then there is the Mountain Ash or Rowan Berry wine. Strip the berries from the stalks when fully ripe and brilliant scarlet, but not over ripe. To each gallon of berries add one gallon of boiling water, cover and allow to stand four days. Then strain, add the yeast and three and a half pounds of sugar to each gallon of liquor. Cover closely, leave to ferment for 16 days, then skim and strain into a storage jar with fermentation trap. When clear and working has finished, bottle and keep nine months to a year.

Rowan berriesI have not given quantity of yeast as there are different yeasts available specially for wine makers. In all the very old recipes which stated “spread one ounce of yeast on a slice of toast and add to the liquor,” I found this always far too much and used only a small teaspoonful to a gallon.

These are only some of the wines which our countryside provides. There are also the wines from our gardens, Rose Petal wine and liqueur, both delicious and health giving and used in days gone by to ‘reduce fevers’ in very ill people.

From the kitchen garden, there is Parsley wine. When well made and fully mature this is a light, rich sparkling wine with no hint of Parsley flavour but with an almost exotic flavour of mingled almonds and Curly parsley leavesvanilla. A glass of it sipped at bedtime was believed to induce natural health-giving sleep.

The humble potato with barley produced a wine which was more like whisky. Excellent for coughs and colds.

Beetroot wine is always popular, and was said to be a sure cure for anaemia. Unfortunately its very ease of making and clearing is its undoing; it looks so clear and sparkling it is used too soon. Beetroot wine carefully made and kept for one and half years is an excellent table wine, tasting of anything but beetroot; instead it is a very pleasant smooth red wine.

The list is endless. I have had a lifetime’s experience of all sorts of wine making. One year, we had a splendid crop of peas and I made quite a lot of Pea Pod wine; it was excellent. Two years later I used it as the basis for a mint liqueur and now, six years from making the Pea Pod wine, I still have a small bottle of Mint Liqueur for very special friends only.

One more special brew is Heather wine; in spite of the work involved picking the tiny flowers—no green or stalk must be used—the result is a wine which makes one really believe the Fairies first discovered Heather wine.

Calendula – Herb of the Month – An Herb of the Sun

By Maryann Readal

Orange flowers against dark green leavesCalendula officinalis is a plant in the Asteraceae family and is The Herb Society of America’s Herb of the Month for May. In my Texas Zone 8b garden, I planted calendula in November and it is now in full bloom, and will continue to bloom until the hot summer sun puts a damper on its bright yellow and orange blossoms. Planted in organic, well-draining soil, and with enough sun, this herb will reward you with its bright blossoms for a very long time. Deadheading does increase its blooms. Calendula can tolerate some freezing temperatures and it does reseed easily. I cannot imagine a garden without it.

This herb has been called marigold or pot marigold since early times. The name marigold is said to have come from the use of the golden flowers during celebrations for the Virgin Mary (Mary + gold), after Christianity became the dominant religion in Europe. Some claim that the golden petals were like the rays surrounding the Virgin’s head. In the thirteenth century, the German poet, Konrad von Wϋrzburg, included calendula among the twelve flowers symbolizing the Virgin (Larkin, 2010). 

The herb was added to soup pots and stews during the Middle Ages. It was also used to color cheese and butter. In India it was a sacred herb, where it adorned statues and temples. 

However, calendula should not be confused with the garden flower we call marigold (Tagetes spp). The flowers of marigold plants, although they look somewhat similar, are not the same and are generally considered to be non-edible. Other important differences include:

  • Calendula originated in the Mediterranean area and some parts of Asia, while the marigold originated in the Americas. 
  • Europeans brought calendula to the Americas. Tagetes spp. were brought to Europe after they landed in America.

Orange flowers on white paper towelThe Romans are believed to have named the calendula after the Latin word calendae (a word referring to the day of the new moon), because they observed that the flowers opened on the day of the new moon. Carl Linnaeus gave the plant its botanical name in the 1750s. 

In early days, calendula was often associated with magical powers. If you wore calendula flowers while in court, you would be victorious in legal matters (Cohen, 2021). People would sprinkle the flowers around their door to keep evil away, and under their beds to ensure that good dreams would come true.

Shakespeare’s writings contain at least six passages about marigolds (Macht, 1955). In several passages, he notes the use of marigold in honoring the dead. The passage in The Winter’s Tale, Act IV, Scene 3, reflects the common belief that marigold was also a heliotropic plant.

Here’s flowers for you;

Hot lavender, mint, savory, marjoram:

The marigold that goes to bed with the sun,

And with him rises weeping.

Glass bottle of light yellow oil surrounded by orange flowersSometime in history, it was discovered that calendula could be used as a medicinal plant. Since early times it was used as an effective treatment for skin irritations. During the U.S. Civil War, the flowers were used to stop bleeding and to promote healing of battle wounds. British garden designer Gertrude Jekyll led a campaign during World War I to raise calendula to supply British hospitals in France (Keeler, 2016). 

In traditional medicines, calendula was used to treat a variety of skin irritations. It was also used to treat earaches, eye and mouth irritations, jaundice, and menstrual problems. Clinical use today shows that it is effective in treating radiation burns (Patil, 2022).  Some recent studies conclude that Calendula officinalis shows promise as an effective medicine, even as a treatment for some cancers (Patil, 2022), but that more clinical research needs to be done.  Its antifungal, anti-inflammatory, and astringent properties make a healing treatment for the skin when infused in oil.

Calendula is also known as “poor man’s saffron.” The petals can be dried and used in place of the more expensive saffron. However, the taste is not the same as that expensive herb. The colorful petals and young leaves can be tossed into salads. The petals can be cooked with rice and mixed into egg salads, cakes, puddings, and soups.  

Orange calendula petals on a white paper towelThe petals have been used as a dye for fabrics and as an ingredient in cosmetics. Dried petals give a nice contrast color in potpourri.  Some say that if the flowers are fed to hens, the resulting egg yolks will have a rich, yellow color (Barrett, 2009). 

This very useful, colorful, and easy-to- grow herb deserves a place in every garden.  For more information, recipes, and a beautiful screen saver, go to The Herb Society of America’s Herb of the Month webpagehttps://www.herbsociety.org/hsa-learn/herb-information/herb-of-the-month.html

Dianthus – Herb of the Month – A Plant of Beauty and Meaning

By Maryann Readal

Photo of pinks, Dianthus caryophyllusDianthus is The Herb Society’s Herb of the Month for April. The timing is perfect as the weather is beginning to be spring-like, and these plants are now available in our garden shops. The Greek botanist, Theophrastus (371-287 BCE), is credited with giving these flowers their name. He combined the Greek word for dios, “divine,” with anthos, “flower” and came up with dianthus. Dianthus have been cultivated and bred for over 2,000 years, and many different colors and flower types have been developed along the way. With successive breeding, however, many of the cultivars have lost their native clove-like scent. 

The old-fashioned plant that our grandmothers called pinks, Dianthus plumarius, can be a perennial or an annual. It is a compact, evergreen, clove-scented, low-growing species of Dianthus. Like other Dianthus, it prefers an alkaline soil and plenty of sun. The perennial variety blooms later than the annual plant, which blooms in early spring. It makes a nice border or rock garden plant and blooms better if the spent flowers are removed. It can be propagated by seed or with cuttings.

“And in my flower-beds, I think, Smile the carnation and the pink.”

                                        – Rupert Brooke

There are several ideas why these plants are called pinks. One idea is that the edges of the flowers look as though they were cut with pinking shears. Another idea is that the name derives from the German word pfingsten, which was the German name for flowers that bloomed around Pentecost (Ecavade,1998).

Glass of Chartreuse liqueurDianthus caryophyllus is the botanical name for the flower we call carnation. It has been in cultivation for over 2,000 years and is native to the Mediterranean region. Other names for this flower are gillyflower or clove pinks because of the clove-like scent of the original flower. Carl Linnaeus described the plant in his Species Plantarum in 1753 and gave the plant its botanical name.

Carnations are an edible flower, if they have not been sprayed with chemicals. In the sixteenth and seventeenth centuries, the flowers were used to flavor wine, earning the nickname “sops-in-wine” (Belsinger and Tucker, 2016). They are also one of the 130 herbs and aromatic plants used to make the French liqueur, Chartreuse, which is still the only naturally green liqueur in the world today. While we do not use them to flavor wine today, they are used as an edible, decorative flower and can be made into syrup or candied. The petals can be put into salads, vinegars, and sauces. 

It is thought that the common name, carnation, came from the Latin word for the crown, corona, worn during Roman and Greek ceremonies. Another theory is that the word came from the Latin word for flesh, Photo of Red carnationcaro, referring to the natural color of the native flower. In religious symbolism, the flower represents “God made flesh in Jesus” or the incarnation. To carry through with the religious symbolism, it is said that the carnation sprung from the tears Mary shed during the crucifixion. The carnation is a frequent artistic floral motif in mosques and Islamic art.  

The carnation holds considerable importance as a symbol today. Indeed, the colors of the flower carry special meanings in the floral industry. Red flowers symbolize love. White flowers mean true love and good luck. Pink carnations are a symbol of a mother’s love and are the Mother’s Day flower. Yellow carnations mean disappointment and rejection (Escavade, 2020). 

Carnations have also been used to give additional meaning to political events. The red carnation was the 20th anniversary of Black January in Azerbiajansymbol of Portugal’s Carnation Revolution when the authoritarian regime was overthrown in 1974. In some countries, it represents the socialist worker’s movement and is often used during May Day demonstrations. In Azerbaijan, red and pink carnations memorialize the people’s uprising against the Soviet crackdown in January, 1990. The red carnation has become a symbol of that tragedy, now christened Black January. The red carnation is the state flower of Ohio. It was chosen to honor Ohio Governor and United States President William McKinley who wore a red carnation until his assassination in 1901. The red carnation is the national flower of Spain, Slovenia, and Monaco.

At Oxford University, some students wear carnations while taking their exams. A white carnation is worn on the first day and red on the last day of exams. Pink carnations are worn on the exam days in between.

Bottle of L'Air du Temps perfumeThe essential oil is also used in making the French perfume, L’air du Temps. Dianthus caryophyllus can be found in European herbal medicine to treat coronary and nervous problems.

Carnations are perennial to Zone 6. They prefer well-draining, alkaline soil in full sun and bloom from summer into the fall. Again, deadheading of the flowers is the key to continuous blooming. As a cut flower, carnations are long-lasting.

And then there is Dianthus superbus, which grows in China, Japan, and in some parts of Europe. This Dianthus is called qumai in Chinese, and the flowers are used in Traditional Chinese Medicine. Its use was first mentioned in the 1st century CE in the Chinese herbal, Divine Husbandman’s Classic of the Materia Medica. Qumai is still used today to treat kidney stones, urinary tract infections, constipation, and dysmenorrhea. 

Researchers are investigating the medicinal potential of this Dianthus species. Recent research indicates that its components may be effective in treating airway inflammation due to asthma (Shin, 2012). In a recent review of the plant, authors concluded “the traditional applications of Dianthi herba have been confirmed, including the treatment of urinary tract infection and dysmenorrhea” (Liu, 2022).

Dianthus superbus can be grown as an annual or perennial and can be propagated by seed or cuttings. Like other Dianthus, it prefers well-draining, alkaline soil in a sunny location. The flowers are harvested Photo of sweet William flowersjust before they open for medicinal applications.

This article would not be complete without at least a mention of Dianthus barbatus, sweet William. This short-lived perennial or biennial species is very different in that it has a cluster of dianthus-like flowers sitting on top of a one to two-foot stem. The cluster attracts butterflies and hummingbirds. It is a favorite plant in cottage gardens. 

Though very little research has been done on the medical applications of sweet William, it does contain saponins. In 1596, Gerard mentioned sweet William in his plant catalog, praising its beauty but made no mention of any medicinal properties.

It is not certain how the name sweet William originated. However, it is a common name used for young men experiencing unrequited love in English folk songs. Interesting to note that when England’s Prince Photo of Kate Middleton's wedding bouquetWilliam married Kate Middleton in 2011, Kate included sweet Williams in her bridal bouquet as a tribute to her husband-to-be (Dillon, 2021).

Know Your Tarragon – The Herb of the Month

By Maryann Readal

French tarragon in a potIt pays to pay attention to plant labels. Especially in the case of tarragon–especially if you are planning to use tarragon in your cooking. If you are growing tarragon for culinary purposes, be sure the label on the plant or seed that you buy says “French tarragon” or Artemisia dracunculus ‘Sativa’, to be sure. If the label says only “tarragon,” you may be purchasing Russian tarragon, which is not the tarragon you want for your roast chicken or béarnaise sauce. 

Tarragon, Artemisia dracunculus, is The Herb Society of America’s Herb of the Month for March. Read on for more information about the plants we call tarragon.

French tarragon — Artemisia dracunculus ‘Sativa’    

The botanical name for tarragon, Artemisia dracunculus, comes from the Latin word meaning “little dragon” or “snake.” It is thought that the plant was given this name because its roots resemble coiled snakes, and the leaves look like a dragon’s tongue. In very early days, this plant was indeed used to treat snake bites. 

French tarragon is famous for its distinctive, anise-like taste and smell. It is a classic culinary herb in French cooking and is one of the four fines herbes, chervil, parsley, and chives making up the other three. It is used in sauces such as béarnaise, remoulade, and tartar. Tarragon vinegar is great for making salad dressings, and French tarragon enhances the flavor of meats and fish.  

Bottles of dried French tarragon and fines herbesEarly medicinal uses of French tarragon include using the herb to combat fatigue. It is said that pilgrims in the Middle Ages put sprigs of tarragon in their shoes to keep them from getting tired on their journey (Kowalchik, 1988). Nicholas Culpeper, a seventeenth-century physician and herbalist, recommended it to treat urogenital conditions, as did Johann Dragendoff, a late-nineteenth-century German pharmacist and chemist (Engels, 2014). 

Native Americans use the wild species of the plant for tea. They treat a wide range of medical problems such as dysentery, colic, rheumatism, and eye and skin issues with it. It is also used to deter insects (Moerman, 1998).

Today, tarragon is used in the European and non-European cosmetology industry, where companies add it to moisturizers, shampoos, and lotions. The essential oil is used in some perfumes. Studies suggest that French tarragon has potential use as a food preservative (Ekiert, 2021).

In 2015, the Nobel Prize in Physiology or Medicine was awarded for the discovery of the effectiveness of some properties of Artemisia annua in treating malaria. Since then, there has been renewed interest in researching the medicinal properties of A. dracunculus as well. The authors of a recent report say, “Contemporary research on the biological activity of the above-mentioned raw materials (leaves and essential oil of French tarragon) has proven new findings in their activity–antibacterial, antifungal, and antiprotozoal effects, as well as extremely valuable antioxidant, immunomodulatory and antineoplastic properties“ (Ekiert, 2021). So, something old is new again.

French tarragon grows in Europe and Asia and prefers the cooler areas of the United States. It needs a cold dormancy period to come back the next year and does not do well in the hot humid areas of the South. It needs fertile, well-draining soil and full sun and can grow to 2-3 feet high. It does not produce viable seeds, so must be propagated vegetatively with cuttings or by root division. Buyer beware when buying tarragon seeds. French tarragon does not produce seeds, so the seeds may be from the Russian tarragon plant, which looks similar but has a different taste.

Russian tarragon — Artemisia dracunculus (syn. dracunculoides)

Russian tarragonRussian tarragon is a French tarragon look-alike. Some people even call it an “imposter tarragon.” Its leaves are a lighter green, have a rougher feel, and do not have much flavor. Russian tarragon produces flowers and viable seeds and is easier to grow than French tarragon. It is considered a perennial in most locations. Early in my herb discovery days, I was fooled by this plant and thought I was buying French tarragon. I wondered why it did not have the anise flavor in its leaves.

Russian tarragon is native to southern and eastern Russia, parts of Asia, and western North America. It is used primarily as a medicinal herb in Russia and Middle Eastern countries to Herbal supplement with Russian tarragonstimulate the appetite, flush toxins from the body, and ease the pain of a toothache, sores, and cuts. Other traditional uses in Russia include as an aid to digestion, relief for nervous conditions, aiding the liver and renal function, and as an anti-bacterial, anti-cancer, and anti-inflammatory agent (Engels, 2014). Recent studies show that the anti-diabetic properties of an extract of Russian tarragon, when taken with body-building supplements, helps to create muscle mass without a need for a high intake of carbohydrates, and helps the body recover from strenuous exercise (Pischel, 2011). 

Mexican tarragon — Tagetes lucida

Also known as Texas tarragon, winter tarragon, and Mexican mint marigold, Mexican tarragon is not in the Artemisia genus at all. But its leaves have a flavor similar to French tarragon, so it can be used as a substitute for it. Its flowers and leaves can be used in salads or dried and ground to use in tea. The fresh leaves and flowers can also be infused in vinegar for use in salad dressings. The leaves were a flavoring in the cocoa-based Aztec drink chocolatl.

Mexican tarragon thrives in hot, humid weather and tolerates freezes and is not fussy about soil, making it an herb that is ideal for the South. This plant also produces bright yellow, daisy-like flowers in the fall that are a nice addition to the landscape. 

Mexican mint marigold in flowerMexican tarragon has been used in traditional Mexican medicine to treat gastrointestinal disorders, relieve mental stress or symptoms of a hangover, as well as for infections caused by parasites (Ventura-Martinez, 2020). Recent studies in the laboratory indicate that the use of Mexican tarragon to relieve some gastrointestinal problems may be an effective use of the herb.

Madalene Hill (1913-2009), noted Texas herbalist and past President of The Herb Society of America, is credited with introducing this South American herb to the United States. For those of us who like to cook with French tarragon and like a nice plant in our garden, we have Madalene to thank.

Bay Laurel – Herb of the Month, Herb of Achievement

By Maryann Readal

Bay laurel as a small treeBay laurel, Laurus nobilis, The Herb Society’s Herb of the Month for February, has been a symbol of achievement, power, and victory from early Greek and Roman times until our present day. The origin of laurel as a symbol rests with Apollo and his love for the nymph Daphne. Unfortunately, the love was not mutual and at her request, the gods turned Daphne into a laurel tree to protect her from Apollo’s advances. Apollo loved the laurel tree and decided to use it as a sign of achievement. The Greeks called the bay laurel tree Daphne.

Early Olympic Game winners were awarded laurel garlands, and Greek poets and musicians wore laurel wreaths. Romans adopted the symbolism and crowned their emperors with leaves of laurel. To this day, the crowns of some European monarchs incorporate the laurel leaf.

An early belief was that the laurel tree was fireproof and could deter lightning strikes. Therefore, laurel trees were planted near doorways or sprigs of laurel were hung in doorways to prevent fire. Nicholas Culpeper in his Complete Herbal said, “neither witch nor devil, thunder nor lightning, will hurt a man where bay tree is” (Mieseler, 2009).

Today, we use terms such as poet laureate and Nobel laureate, both describing someone who has achieved a high honor in their field. We are familiar with the phrase “resting on one’s laurels,” which means that someone who has achieved much can rest on their achievements and need not do more. “Our word baccalaureate comes from the custom of crowning young doctors of medicine with laurel leaves and berries, bacca lauri,” notes Theresa Mieseler (2009). Laurel branches are still used as a part of graduation ceremonies in some colleges and universities worldwide today. A laurel wreath is awarded to the winner of the Grand Prix. You will also see the laurel wreath on coins and on the emblems of nations. Its symbolism is meaningful.

The Victorians adopted the laurel as a symbol of never-ending love. My own wedding ring is a circle of laurel leaves, which I did not realize the significance of until researching for this article. The bay laurel motif has also been used in architecture. This herb is a part of our culture without us even realizing it.

Cultivation
Laurus nobilis is a plant that prefers a warm climate. It was thought to be native to the Mediterranean area; however, genetic testing shows that its origin is in the Middle East. In my USDA Zone 8b garden, I can grow bay in the ground year round. But to be safe, it should be grown as a container plant, unless you are willing to test it in the ground in zones less than 8.  It is an evergreen tree or shrub depending on how it is pruned, and can reach a height of eight to ten feet or more. It likes full sun or partial shade. It is dioecious, meaning there is a male plant and a female plant, and its small yellow flowers bloom for only a few weeks in the spring.

Bay with small yellow flowersPropagating bay takes patience as it is very slow to germinate and grow. The Herb Society of America’s guide to bay offers a method for propagating bay laurel.

The ASPCA cautions that bay laurel is toxic to dogs, cats, and horses. Caution is advised when purchasing other plants with laurel in the name, such as mountain laurel (Kalmia latifolia) and cherry laurel (Prunus laurocerasus). These are not in the same family as bay laurel and are poisonous.

Uses
We grow bay laurel as a source of fresh leaves for cooking. It is one of the herbs in bouquet garni and is used to flavor soups, sauces, stews, and roasted meats and fish. It is sometimes boiled in milk or cream to flavor puddings. Madalene Hill and Gwen Barclay call it a “liaison” herb because it helps to blend flavors together (Mieseler, 2009). It is best used in recipes requiring a long cooking time. The leaf does not soften with cooking and should be removed before serving. California bay, Umbellularia californica, can be used as a substitute for bay laurel in cooking; however, its flavor is stronger than Laurus nobilis.

Round-pruned laurel trees flanking a doorway at Greifenstein CastleBay laurel branches are pliable and lend themselves to making wreaths. The leaves are also used for potpourri. Many of us remember the old-fashioned way of keeping flour and grains insect-proof by adding a bay leaf or two to the container. The essential oil of bay is used in perfumes and soaps.

Of course, bay has had many uses as a medicine throughout history. A renowned use has been for treating rheumatism. It has also been used in traditional medicines to treat stomach issues, gas, and respiratory ailments.

Recent studies focus on its antiviral and antibacterial properties, particularly effective for treating MRSA (Otsuka, 2008). A recent article in Environmental Chemistry Letters hypothesizes that a possible reason for a lower incidence of COVID mortality in southern Italy may be due to extensive forests containing bay laurel. The emission into the air of immuno-modulating volatile organic compounds (VOCs) found in bay laurel are suggested as a reason (Roviello, 2021).

Mastic: Something Herbal to Chew On

By Chrissy Moore

George Arisitidou from Great British Bake-offI fully admit to living under a rock. Many a friend and coworker has informed me of this character “trait.” Because I am not so worldly as others, I learn things by more circuitous routes. For example, my latest herbal discovery resulted from watching a recent episode of The Great British Bake Off. George, one of the bakers, remarked that he was including mastic in his bake. Of course, Paul Hollywood, one of the show’s hosts, commented with raised eyebrow, “A little mastic goes a long way.” George returned fire, stating, “You can never have too much mastic!” Clearly, mastic was near and dear to this Greek baker’s heart.

Unless you’re familiar with Greek cuisine or custom, as I am not, you may not have come across mastic–also known as Chios mastiha–in your comings and goings. But, if you are anything like me, you’d immediately start rooting around for information about this herbal ingredient, like a squirrel for a nut. I’ll save you some digging.

Map of Pistacia lentiscus native rangeMastic is a resin extracted from Pistacia lentiscus cv. Chia L. (Chios mastictree, mastic), which is a member of the Anacardiaceae family (GRIN-Global; Browicz, 1987). (Cashew, Anacardium occidentale L., and pistachio, Pistacia vera L., are also members of this family.) This small shrubby tree is native to numerous countries around the Mediterranean, from southern Europe to northern Africa to western Asia (Sturtevant, 1919), but it is most notably—and historically—linked to the Greek island of Chios in the northern Aegean Sea, about nine miles west (the way a crow flies) of the Turkish Çeşme peninsula.

It’s so linked to this island, in fact, that the island is referred to as the “mastic island,” since it has been the world’s largest producer of mastic resin for many years (Groom, 1992). “The production of mastic currently amounts to 160—170 tons per annum and plays an important role in the economy of the island Mastic harvesting preparationconstituting the main source of income for approximately twenty villages in the south of Chios” (Browicz, 1987). The trees reach their full height after 40 – 50 years, but harvesting reaches its full potential after 12 – 15 years (FAO, 2021). Similar to frankincense (Boswellia spp.) and myrrh (Commiphora spp.), the mastic harvester nicks the tree bark to produce “tears,” or droplets, of resin, which then harden and are scraped off. These hardened blobs of resin are gathered and taken for processing (masticlife.com).

The resin undergoes some in-house cleaning and processing before it is given to the cooperative, Chios Gum Mastic Grower’s Association (CGMGA), for grading. Afterward, the graded mastic gum is shipped to and processed by the Union of Mastic Producers, who grinds it into a powder (FAO, 2021). The powdered form can then be incorporated into various foodstuffs, medicinal products (Varro et al., 1988), or left whole for chewing. Mastic is considered an early form of chewing gum, particularly for freshening the breath (Schery, 1972; Simpson and Ogorzaly, 2001; Sturtevant, 1919; Tyler et al., 1988). Currently, the largest importer of Chios mastic is Saudi Arabia, where chewing gum companies have incorporated the tree resin into numerous candy and confectionery products, particularly those of the dietetic variety (Batook, 2021; FAO, 2021).

Greek plants: Pistacia lentiscus (mastic tree), overlooking Finikas, SyrosIf you haven’t picked up on the etymological relationship by now, translated from the Greek, mastic means “to gnash the teeth,” or in modern parlance, to chew or masticate…an appropriate term for the gummy treasure. Spurred on by the mention of it on The Great British Bake Off, I was on the hunt for this chewy, new-to-me herb. Fortunately, we have a husband-and-wife team of volunteers in the National Herb Garden, who just happened to live in Greece for a number of years. What better resource than these two to probe for information—outside of knowing a native of Chios, of course.

Bottles of mastika and ouzoThey confirmed that mastic was, indeed, a ubiquitous flavoring in parts of Greece, including its use in mastika, a sweet liquor flavored with the resin (something else I had never heard of before) and ouzo, another Greek spirit. They said that you can find mastic gum and Turkish delight-esque candies all over Chios (well, in Greece, generally, and also in surrounding areas), as well as in well-appointed Mediterranean markets, even in the United States. I asked them what it tastes like, and they both hemmed and hawed trying to find the right words to describe its unique flavor. I immediately assumed it would be “pine-y” or “camphor-y” or something of the sort, since it is a tree resin, after all, but they both still hemmed seeming to suggest that it wasn’t exactly that strong. 

Well, what then? What does it taste like? The only remedy for this inquisition was for them to seek out a market near where they live outside of Washington, DC, that might carry some sort of mastic-containing products. And they delivered! The following week, I was handed not just mastic chewing gum, but also mastic jellied candy. The candy was passed around amongst our volunteer group, and those adventurous enough to try plucked out a confectioner’s sugar-covered cube and commenced to masticate.

Mastic jellied candyThey were right: not exactly pine-y, but not exactly anything else either. I moved the candy around in my mouth trying to find words to describe it. Yes, it certainly had resinous, “pine-y” kinds of notes, but it also had a bit of a flowery essence to it. It was certainly unlike what I was expecting. Not nearly as strong as I thought it would be, but also not without character.

Not being particularly chef-y (I’m more of the baking sort), I’ve been trying to imagine what it would taste like in cooked or baked goods. Given that mastic rides that pine-y line, a heavy-handed cook might well overdo it. (Paul Hollywood was not without legitimate concern.) It’s a bit like using rose or lavender in food preparations: too much, and it can veer dangerously close to soap territory. But, used in moderation, it could pair nicely with other herbs/flavors. If you try it, let me know how it turns out!

Picture of Fahrenheit pefumeSpeaking of other herbal uses, mastic is also found in perfumes, personal hygiene products, and medicines. The resin has been used for centuries as a component of incense, particularly for the production of “moscholivano, [which] is a solid essence that, when burned, releases a pleasant odour” (FAO, 2021) and as an ingredient in chrism, the anointing oil used in the Eastern Orthodox Church (and others). In The Perfume Book, Groom says, “In early times the gum was used in pomanders and the oil was used to absorb other plant fragrances in the process of enfleurage. In modern perfumery, the extracted oil is used as a fixative in various perfume compounds; it appears, for example, in ‘Fahrenheit’.” According to Verrill, the resin is used as “a fixative for honeysuckle, lavender, sweet pea, mimosa, and other perfumes” (1940).

Medicinally, mastic has taken on a number of roles over the centuries. In early Greek history, mastic was considered a cure-all in traditional Greek medicine, “relieving the diverse gastrointestinal disorders, such as abdominal pain, dyspepsia, gastritis and peptic ulcer for more than 2.500 [sic] years. More precisely, Hippocrates, Dioscorides and Galenos, among other Ancient Greek physicians, cited its properties and recommended its use” (CGMGA, 2021). A lengthy paper published by the Chios Gum Mastic Grower’s Association states,

“Nowadays, it is used as a seasoning in Mediterranean cuisine, in the production of chewing gum, in perfumery, in dentistry, and for the relief of epigastric pain and protection against peptic ulcer. It is of vital importance to mention that solid scientific evidence is constantly being produced regarding the therapeutic activity of Chios Mastiha. Its gastro-intestinal, antioxidant, anti-inflammatory, antidiabetic, antimicrobial, and anticancer activity, as well as its beneficial effects in oral hygiene and in skin care are firmly documented…. Mastiha is considered now as a traditional medicine for both stomach disorders and skin/wounds [sic] inflammations” (2019). In the Greek City Times, 12 December 2021, the authors note that studies of mastic’s wide-ranging health benefits are ongoing, merely echoing, perhaps, what thousands of Chios natives have known for centuries. (Some of us are a little slow on the uptake!)

Picture of megilp varnishIf you thought this story was over…not so fast. Mastic has a few more tricks up its sleeve. Mastic is used as a component of dental fillings, in dentifrices, and mouthwashes, helping to knock down pesky bacteria in the mouth. It should also be noted that “thanks to its quality as a colour stabilizer, mastiha is used for the production of high-grade varnishes” (CGMGA), such as those used in oil painting (megilp), and as a protective coating on photographic negatives. Rosin, a by-product of gum mastic’s distillation process, is used in myriad industries as well.

To put an exclamation mark at the end of this herbal story, mastic is certainly not a one-trick pony. On the contrary, I think Paul Hollywood was wrong and George was right: “You can never have too much mastic!” Something to chew on.

An Incredible Herb Right Under Our Feet…or Above Our Heads

By Katherine Schlosser

For most of us, our garden tools are cleaned and stored, the holidays have passed, and we have a little more time to simply enjoy what we find in meadows, forests, fields, and even in our own backyards. Lichens can fill a part of the void we may be feeling. Their curious forms and means of growing and spreading, with which many of us are unfamiliar, can fill our minds with the wonders of things we normally pass without notice.  

There are more than 5,000 species of lichen and lichen-dependent fungi in North America, with colors ranging from blues, lavender, yellow, red, orange, and gray to many beautiful greens. Color in lichens can depend on whether they are wet or dry. A major paint company even created a color they call Lichen to mimic the natural, earthy beauty of the organism. Perfectly described by Ed Yong in a July 2016 issue of The Atlantic, “They can look like flecks of peeling paint, or coralline branches, or dustings of powder, or lettuce-like fronds, or wriggling worms, or cups that a pixie might drink from.”

The forms lichens take are grouped in one of several general types, including:

Foliose – mostly flat with leaf-like structures, with each side having a different appearance 

Fruticose – may have tiny “branches” and a bushy appearance

Crustose – appear like flat, crusty painted spots on trees, branches, logs, roof, or rocks

Other forms include:

Filamentous – stringy and hair-like

Gelatinous – jelly-like and somewhat formless 

Leprose – have a powdery appearance

Squamulose – small, flat leafy scales with raised tips

Lichens have been used by humans for thousands of years, mostly as medicinals but also as foods, beverages, dyestuffs, cosmetics, brewing, animal fodder—even as an indicator of atmospheric pollution. As useful as they have been, our understanding of lichens has been slow.

Until the late 1800s, lichens were still thought of as plants. In 1868 Simon Schwendener, a Swiss botanist, identified them as a fungus and an alga living in a cooperative relationship. Later botanists recognized the relationship as mutually beneficial, with the alga using sunlight to produce nutrients and the fungus providing shelter, water, and minerals.

Lichen, Rough speckled shield -BRP 4-30-09

Botanists held with the partnership assumption, even though they struggled unsuccessfully to get lichens to grow in the lab. What they were missing was brought to light 150 years later by Tony Spribille, who spent years collecting lichen samples and screening them for genes of basidiomycete fungi. 

What had been missed by generations of lichenologists was basidiomycetes, the third member in the partnership of lichens. With the right combination of two fungi and an algal species, a lichen would form. There is much more to learn, but thanks to Spribille, the journey has begun.

Quoting Ed Yong again, Spribille and his associates found that, through a microscope, “a lichen looks like a loaf of ciabatta: it has a stiff, dense crust surrounding a spongy, loose interior. The alga is embedded in the thick crust. The familiar ascomycete fungus is there too, but it branches inwards, creating the spongy interior. And the basidiomycetes? They’re in the outermost part of the crust, surrounding the other two partners. ‘They’re everywhere in that outer layer,’ says Spribille.” And the mystery was solved.

The most frequently noticed are the crustose lichens seen on trees, often looking like someone spray-painted blotches on tree trunks, or left a trail marker. These can vary from shades of gray to greens, blues, and yellows. They are attractive to me but lead some to think their tree has been attacked by disease.  

No need to panic; these lichens don’t sink their “teeth” through the bark and into the tree. However, there are some lichens that contribute to the breakdown, or weathering, by physical and chemical processes, of the rocks to which they are attached. Physical effects occur by penetration of the rocks by hyphae and the swelling of organic and inorganic salts. Chemical processes include the “excretion of various organic acids, particularly oxalic acid, which can effectively dissolve minerals” (Chen 2000). The result is the eventual breakdown of rock into the mix of ingredients making our soil.

Pixie cup lichen and Dracanum moss spp IMG_4681As an aside, Alexandra Rodrigues and associates inoculated newly created stained glass samples with fungi previously isolated and identified on original stained glass windows. They found that “fungi produced clear damage on all glass surfaces, present as spots and stains, fingerprints, biopitting, leaching and deposition of elements, and formation of biogenic crystals”  (Rodrigues et al, 2014). Let that be a warning to keep your stained glass windows clean. 

Of particular interest to members of The Herb Society of America are the useful aspects of these frequently overlooked species that are building blocks of our green planet. Found growing in moist, shady places, they also thrive in hot, dry lands. Though widely spread across the globe, growing on cold mountaintops to hot deserts on rocks, trees, fallen logs, on fertile soil or dry crust, each species has specific nutrient, air, water, light, and substrate requirements.

They vary widely in usability too, from serving as alerts for the presence of air pollution to providing survival food. Rock tripe, most often seen as green to black leafy-looking masses on boulders, might be the last thing you would consider putting into your mouth, but it turns out that, for thousands of years, they have saved people from starvation. After boiling and draining a few times, they can be made into a soup, even if barely palatable. 

Cetraria islandica, Darya Masalova CC-BY-NCOne of the more interesting lichens is known as Icelandic moss (Cetraria islandica ), which first came to my attention in the form of Fjallagrasa Icelandic Schnapps. If you look closely at the bottle pictured, you will see a sprig of the lichen in the bottle. Hand picked from the wilderness of Iceland, the lichen is steeped in alcohol, which extracts the color and flavor of the lichen. Sadly, I have not tasted it myself but have heard from a friend, and read, that it is a drink that requires a slight adjustment of expectations. Regardless, I’m almost willing to make the trip to Iceland just for the experience. The manufacturer recommends drinking “in moderation in the company of good friends”—a sound recommendation.

Beyond alcohol, this particular lichen has multiple medicinal uses, too. The active compounds in Icelandic moss have demonstrated antioxidant, antibacterial, and antifungal properties (Grujicˇic´ et al., 2014).The mucilaginous compounds (polysaccharides) aid in soothing oral and pharyngeal membranes, relieving coughs of common colds.

Scandinavian countries were long known to use Icelandic moss in making breads and soups. They dried the moss, reconstituted it, then dried it again and ground it to mix into flour. Due to the polysaccharides, the lichen added structure as well as flavor. Many other cultures used it as an addition to flour to cut the expense of flour. Used far less now, over the years, it was an important source of nutrients for many people.

Parmotrema perlatum, commonly known as black stone flower, is used as a spice in India and elsewhere, and is often added to Garam Masala blends. As found, it has no fragrance; exposed to the heat of cooking, it releases an earthy, smoky aroma. 

Unlikely as it sounds, some lichens can be fragrant, and some act as a fixative in the preparation of cosmetics and perfumes. Oakmoss lichen, used in perfumery, is found on oak trees, as well as a few other deciduous trees and pines.

A number of lichens are used in the dyeing and tanning industries. If you took high school science, you are familiar with Litmus strips. Those strips are made from litmus, which is obtained from a couple of species of lichens, Roccella tinctoria and Lasallia pustulata.

Winter may be upon us, but there is still plenty to see and study right under our noses in the garden, yard, and out walking on trails. Take notes, take photos, and spend a lazy afternoon identifying what you have found and what uses it may have. Future ventures into the forest will hold considerably more interest for you.

Enjoy!
