2023 HSA Notable Native™ Shrub or Tree: Juniperus communis

By Katherine Schlosser

Juniperus communisThough declared the most widespread of juniper species and appearing widely across the United States, there are eighteen states in which Juniperus communis does not grow as a native: NJ, DE, MD, WV, KY, MO, IA, NE, KS, OK, AR, TN, AL, MS, LA, TX, or HI. Those states may have other juniper species, or cultivated plants, but Juniperus communis is not native to their soil (Flora of North America)

Robert P. Adams identifies 18 Juniperus species in the continental U.S. with an additional five varieties and three forma (Adams, 2019). The Flora of North America includes 13 species. Globally, the number is higher, primarily in the Northern Hemisphere.

These perennial evergreens grow from one to four feet tall, generally in a shrub-like form sprawling across rocks or soil and occasionally—especially in the northeast—growing upright to as much as 30 feet tall or more. Seed cones mature in one to two years and will last for several months beyond maturity. Each cone bears 1‒13 wingless seeds.

Glass of gin and tonicWell-known to us as the flavoring in gin, juniper species have been known in this country for many years for a multitude of purposes, from culinary, medicinal, and insect control to ceremonial and utility uses.  

Several Indigenous Peoples tribal groups tied boughs of juniper to the tops of their homes to discourage lightning strikes (Murphey, 1990). Juniper bark and leaves were considered sacred and used ceremonially (Kavasch, 2005).

Medicinal uses were broad, including for treatment of high blood pressure, as a diuretic, and to improve the appetites of the elderly (Garrett, 2003). A salve was made of the oil from the cone, mixed with fat, to protect wounds from flies. Smoke from the burning wood or leaves was inhaled to treat colds and to repel insects. Tea was given to induce a speedy delivery, and in 14th-century Europe, in the midst of Black Death (bubonic plague), juniper tea was used to sterilize bandages (Harrington, 1967). 

We have learned from history; and studies on the properties and efficacy of juniper essential oils continue, looking particularly at the antiseptic and antibiotic possibilities. The Food & Drug Administration has approved an oral medication to treat fungal infections (Cabello et al., 2010).

Juniperus communis conesThere are many recipes for using juniper berries, which can now be found in the spice section of many grocery stores. While some may find the taste a bit strong or resinous, others find it adds wonderful flavor to meat dishes, vegetables, and even baked goods.  

The scent of gin is prominent in crushed berries, which blend well with cheese and fruit. The berries (actually cones) can be eaten raw, but are most often dried. Even then, it is suggested that not too many be eaten at one time. Just a few will flavor enough meat or game for four people.

The essential oil of juniper is composed primarily of monoterpene hydrocarbons such as α-pinene, myrcene, sabinene, limonene, and β-pinene, lending some familiar lemony, spicy, and piney scents.

crushing juniper berriesWe learned from Indigenous Peoples to dry, then powder, the fruits, using the powder much as we do black pepper. Others teach burning the leaves, pouring boiling water over the ashes, straining the liquid, and using it as a flavoring.

The wood of juniper trees is strong and has been used, in spite of its often small size, for long-lasting craft items for household and kitchen use.

There was a time, prior to my HSA membership, when I dismissed Juniperus communis for landscape use, seeing it most often used commercially where it seemed to attract trash. I know better now that, in well-kept landscapes, it is lovely, its history is interesting, and its culinary uses delightful. I no longer have need for contraceptives or speedy deliveries, but a bit of gin once in a while might be good for aching knees after a day in the garden.

Herb of the Month: Chives – Tiny Herb with Impact

By Maryann Readal

A bee sits on purple chive flowersChives, Allium schoenprasum, is a flowering herb in the Amaryllidaceae family. It is in the same family as leeks, onions, garlic, Chinese chives, and shallots. Its hollow, grass-like stalks and star-shaped purple flowers are edible.The bulbs are small, unlike other members of this family, and are typically not eaten. It is an easy-to-grow perennial herb that likes sun or part sun and well-draining soil. In warmer climates chives bloom in the spring, and in cooler areas the early summer. Plants die back in cooler regions but will return from the tiny bulbs in the spring. It is the only Allium that is native to North America, Europe, and Asia. It is interesting to note that the term “chives” is most often used in the plural form. Perhaps that is because you cannot eat just one of them.

Chive stalks with purple flowers growing among rocksDue to the sulfur compounds in chives, they have been used as insect repellent in gardens throughout history. It is particularly effective against Japanese beetles. Despite  their sulfur smell, chive flowers attract bees and other pollinators to the garden. In a study conducted by the UK Insect Pollinators Initiative’s Agriland Project in 2014, chives were named as one of the ten highest sugar producing plant species for pollinators (Memmott, 2014). It also has been found that the juice in chive leaves is effective in combating some fungal infections and mildew, giving another great benefit to having it growing in the rose garden since roses are susceptible to fungal pathogens.

Loaded backed potato with bacon, sour cream, cheese, and chivesChives are also a good addition to rock gardens, with their roots keeping dirt from washing out from between the rocks. They would be a nice addition to fairy gardens with their green spiky stalks and purple flowers. Chives can be grown indoors on a sunny window sill for convenient use in cooking. When harvesting chives, it is recommended to cut the stalks just above the soil line to promote new growth of stems and bulbs. Stems should be cut several times during the growing season. 

Chives’ main use is as a culinary herb. They give a mild onion taste to eggs, sour cream on baked potatoes, deviled eggs, spreads, and salads, and they dress up any creamed soup. Because of their delicate flavor, they’re best used as a garnish or added at the end of cooking. Chives are an ingredient in some traditional Polish, German, and Swedish dishes, and are included in the French fines herbes along with chervil, tarragon, and parsley. The flowers make a tasty and colorful addition to vinegar. Chives can be chopped and then frozen for later use. However, the fresh leaves have the most flavor.

A black and white illustration of Pliny the ElderChives have been used as a medicinal plant for 5,000 years. It is said that Marco Polo brought chives to the west from his travels to China where they’d been used as a medicinal and culinary plant for 2,000 years. The Romans used them to treat sunburn and sore throat, as a diuretic, and to reduce blood pressure. Pliny the Elder, in his book Natural History in 77 A.D., wrote that “importance has recently been given to chives by the emperor Nero, who on certain fixed days of every month always ate chives preserved in oil, and nothing else, not even bread, for the sake of his voice” (Pliny, 1938). The Roman poet Marcus Valerius Martialis, however, cautioned that “He who bears chives on his breath, is safe from being kissed to death” (Small, 2013). The Romanian Gypsies used chives for fortune telling. During the Middle Ages, some people thought that hanging a bunch of chives in the house would keep evil spirits and sickness away. Also during the Middle Ages, chives began to be incorporated into soups and stews. When the colonists came to America, they brought chive seeds with them. In 19th century Holland, farmers were known to feed chives to their cows to produce milk with a different taste.

A hand holds a bunch of chive stalksToday, according to researchers, chives and other members of its family are being looked at for their usefulness in medicine. According to Varinder Singh et al., “Scientific evaluation of chives validates its traditional claims and demonstrates diverse pharmacological potential including an anti-inflammatory, anticancer, antioxidant, anthelmintic and antihypertensive.” But the authors state that further research is still needed on the bioactive compounds of chives. In addition, it would seem that a large number of chives would need to be eaten to achieve significant health effects.

Chives are The Herb Society of America’s Herb of the Month for April. For more information about chives, a screensaver, and recipes, please visit the website.

Rubber Production on the High Plains?

By Scott Aker

Ericameria nauseosa in flowerIt seems that as I continue my career in horticulture, there are plants that I come back to over time. With my recent move to Wyoming, I have come back to a lot of plants that are familiar from my childhood in western South Dakota. One of those is rubber rabbitbrush, Ericameria nauseosa. When I first learned it, it was Chrysothamnus nauseosus, but taxonomists assigned it to a different genus. I first knew it from visits to Badlands National Park where it grew as a low, billowy shrub among the desolation of nearly white decomposed Pierre Shale.  

Ericameria nauseosa bright yellow flowersFast forward to last fall when I arrived in Cheyenne to look for a new home. It had been a dry year, as they often are here, and anything that was not watered frequently was dormant and brown. Rubber rabbitbrush, however, had burst into bloom with its golden flowers covering each defiantly green shrub. I passed by one home with much of its front yard devoted to the shrub, and upon close inspection, I discovered that the stems were an attractive shade of green. The ones I knew from South Dakota had gray stems. It turns out there are two subspecies—Ericameria nauseosa ssp. consimilis has green stems and is more western in its distribution, while Ericameria nauseosa ssp. nauseosa has gray stems and is more eastern.

Ericameria nauseosa foliageThe species name refers to the smell of the foliage when crushed. It is described as pineapple-like by some and as foul and rubbery by others. While the scent may depend on the sniffer, the fact that the whole plant contains rubber in high amounts is beyond doubt. As early as World War II, it was studied as a potential domestic source of rubber when much of the world’s rubber production fell into Japanese hands. It is a small source of industrial rubber today. Perhaps one of the factors limiting its use as a source of rubber is the long time of six years that it takes for the plant to reach a stage of maximum rubber content. Curiously, the rubber found in rubber rabbitbrush is not in the form of latex; it is rather in the form of solids in the inner bark and outer ring of xylem just inside the bark. Ericameria nauseosa ssp. consimilis may have up to 4% rubber by dry weight, double the amount for Ericameria nauseosa ssp. nauseosa. The rubber from rubber rabbitbrush is also free of the proteins that cause problems for those with allergies. 

Ericameria nauseosaI was interested to learn why rubber rabbitbrush is only of minor commercial importance. It turns out that guayule, Parthenium argentatum, was designated as “the official crop for domestic production of rubber” (Bowers, 1990) even though it is not as cold hardy as rubber rabbitbrush. Even plants cannot escape politics.  Perhaps it is the six years needed to reach peak rubber production. It may also be the quality of the rubber, which is judged by the molecular weight of each carbon chain; longer chains and higher molecular weight are desired. Rubber rabbitbrush does not have the highest molecular weight (Ma, 2019), and that may be why it is not widely grown or harvested for commercial rubber.

Ericameria nauseosa nicked branchThe leaves and trichomes also contain about 35 percent resin by dry weight. The resin contains aromatic (in the hydrocarbon ring sense, not in the olfactory sense) terpenoid compounds that could be used in manufacturing plastics. Some of the terpenoids may be used as nematicides and insecticides (Finley and Neiland, 2013).

Like nearly every native plant, rubber rabbitbrush is used by several tribes for various purposes. The Navajo use the bright yellow flowers to dye clothing, leather, and crafts. The Hopi also use it as a dye and weave wedding belts with the branches. Dried leaves and flowers are boiled in water to create a soak used to relieve pain and swelling caused by arthritis. Ceremonially, it may be used to treat someone who has been attacked or possessed by an unwanted spirit. Shoshone tradition uses it this way to treat nightmares, but it is rarely mentioned because the treatment can backfire (Clifford, 2019). Ground up stems can be used as chewing gum (Kershaw, 2000). Cottony white insect galls that form on the branches are strung as beads to make a necklace that is hung around babies’ necks to stop their drooling (Curtin, 1997). The galls can also be used to treat toothache and stomach problems (Dunmire and Tierney, 1995). Even if it had no herbal uses, rubber rabbitbrush is a very attractive native plant that deserves to be in High Plains gardens, and if you repeat its name rapidly, you can greatly improve your oratory skills!

Ericameria nauseosa graveolens and E. n. ssp. nauseosus along the roadsideThere is a wide median just outside the Cheyenne Botanic Gardens in the middle of Carey Avenue. Upon arriving in my position as Director, I was told that the City of Cheyenne had a thought that this expanse of turf should become a water-wise landscape with native plants. Of course, rubber rabbitbrush is one of the plants that comes to mind. Its deep root system and ability to withstand high pH and salinity make it one of the few plants that might succeed in this tough spot. The soft, billowy texture created by the fine branching habit and tiny leaves in summer, the stunning and bright yellow flowers that cover the shrub in late summer and early fall, the fluffy seed heads that follow and persist well into winter, and the stunning green stems make it lovely in every season. It is heavily used as a pollen and nectar source by native bee species, because it produces so many flowers when very few plants are in bloom.

Ericameria nauseosa flowers and honeybeeRubber rabbitbrush may grow as tall as six feet. Plant Select® has selected a compact cultivar called Baby Blue that tops out at 28 inches if the species is too tall for you. Because it can recover quickly from hard pruning and blooms on new growth, you can also cut it back nearly to the ground in late winter or early spring to keep it in bounds.

Cranberry – Herb for the Holidays

By Maryann Readal

Cranberry fruitThe cranberry, Vaccinium macrocarpon, is a native American fruit, as well as an herb that is full of nutrition and medicinal value. It is The Herb Society of America’s Herb of the Month for November. Cranberry is native to the eastern part of the United States, southern Canada, and the southern Appalachian area. It is a perennial, low–growing, trailing vine. The vine can reach a length of six feet with upright stolons growing up along it. It is these upright stolons that bear the flowers and then the cranberry fruit. Rich, boggy wetlands are the ideal environment for cranberries to grow, but they are also grown in areas with a shallow water table. Cranberry plants in bogFlowers bloom in May and June on the stolons and terminal ends of the vine. Because the flower pollen is too heavy to be carried by the wind, pollination is dependent on native bees and honey bees. Fruit matures after about 80 days, and harvesting begins at the end of September and extends into October. To harvest the berries, the growing area is flooded. Then, the plants are “beaten” with specialized equipment causing the berries, which have four small air pockets in them, to float to the top. (These air pockets also make fresh cranberries bouncy.) The floating berries are corralled into one area and then harvested using conveyor belts. This “wet harvesting” method is used for berries that become cranberry juice and sauce. "Wet" cranberry harvestingAbout 5% of berries are “dry harvested” and packed for use as fresh fruit. Dry harvesting is done by mechanized “combing” of the fruit from the vines (Cranberry Institute, n.d.).

Native Americans use the cranberry to make pemmican, a dried food cake. They were the first to use cranberries to make a sweet sauce using maple sugar (Caruso, n.d.). They also use cranberries as a poultice to treat fevers and wounds. The juice is used as a dye for their blankets and rugs.

Cranberry blossomThe Pilgrims named the berry “crane berry,” because the unopened flower resembled the head, neck, and bill of a crane. The name was later shortened to cranberry. Some also called it “bear berry” because bears liked to eat the berries.

Cultivation of cranberries began in the early 1800s in the northeast US. The first commercial cranberry bed was planted by a Revolutionary War veteran, Henry Hall, in 1816 in Massachusetts. Today, more than 40,000 acres of cranberries are farmed in the United States alone (Cranberry Marketing Committee, 2022). In the beginning, shipments of cranberries were packed in water in barrels containing 100 pounds of fresh fruit. The 100-pound barrel continues to be the standard measurement for cranberries. 

Ocean Spray founder, Elizabeth LeeElizabeth Lee, in New Jersey, made and sold the first cranberry sauce in 1917. Due to the success of her sauce, Bog Sweet Cranberry Sauce, she partnered with two other growers and formed the company Ocean Spray in 1930.

Cranberries contain a high amount of Vitamin C.  In the early days, they were eaten by sailors to prevent scurvy. Today, cranberries are thought to prevent urinary tract infections (UTIs). However, studies show that cranberries do not cure these infections (Mount Sinai, n.d.).  But chemicals in cranberries may help to prevent bacteria from sticking to the urinary tract walls, which could prevent UTIs from developing. In 2020, the FDA allowed cranberry producers to label their products saying that there is “limited” evidence to support the claim that cranberries prevent urinary tract infections.  

Cranberry supplementRecent research shows that cranberries can be healthy in other ways. Some research suggests that they can prevent bacterial infections that cause ulcers in the stomach. They also may help slow the buildup of dental plaque. Cranberries have two dozen antioxidant compounds, which help protect cells from damage that can lead to serious diseases such as cancer and heart disease (WebMD, 2020). Cranberries also contain salicylic acid, which can help reduce swelling and prevent blood clots from forming. 

In 2002, several studies found that the antioxidants in cranberries appear to give some protection against Alzheimer’s disease (Univ. of Maine, 2012). In the past, cranberry has been used to treat the common cold, enlarged prostate, and kidney stones. However, there is no good evidence to support the effectiveness of these uses of cranberry.

Resized_20220928_122605Cranberries are a popular accompaniment at holiday meals. A meal of roasted turkey is not complete without the sweet tanginess of cranberry sauce. About 20% of cranberries are consumed at Thanksgiving. It is interesting to note that cranberries are more tart than lemons and also contain less sugar than lemons (Alfaro, 2021). Adding a quarter teaspoon of baking soda can help reduce the tartness of cranberries and, therefore, reduce the need for extra sugar. 

Fresh, frozen, or dried cranberries can be added to pies and cakes. Dried cranberries may need to be rehydrated before being used. Dried cranberries can also be substituted for raisins in many recipes. Fresh Handful of harvested cranberriescranberries are used to make sauces and jellies. When cooking fresh cranberries, they should only be cooked until the skins begin to pop. Chopped fresh cranberries make a colorful addition to salads. They can be a zingy substitute for cherries or pomegranates as well. Fresh cranberries can be frozen and kept in the freezer for up to a year. Frozen cranberries do not have to be unthawed before using. The Cosmopolitan drink is made with cranberry juice. White cranberry juice is made with cranberries that have not yet ripened.

Fresh, dried, or frozen, this is the season to add cranberry, one of our native fruits, to your meals for color, taste, nutrition, and good health. For more information, a beautiful screen saver, and recipes for using cranberry, please visit The Herb Society of America’s Herb of the Month webpage.

The Power of One: A GreenBridges™ Story

by Debbie Boutelier

(Editors’ note: This article originally appeared in a recent HSA newsletter. It has been edited for clarity for this post.)

Pipevine swallowtail butterflyIn a recent GreenBridges™ presentation, I mentioned the power of one several times. I’d like to share a short story about how the power of one worked in my GreenBridges™ garden. My garden was certified a number of years ago, and I have been slowly incorporating more native plants into my landscape. (We all NEED a reason to buy more plants, right???) 

When COVID hit, and we all had to stay home more, I decided it was time to kick my garden projects into full speed and actually complete those projects that had been in the planning stage for a while. (I’m not going to admit how long they were in the planning stage, so don’t ask!) I made a pledge to myself at that time that at least 90% of the plant material to finish these projects would be natives. I knew a lot of our local natives, but it was so much fun researching the lesser known species and then actually finding them. 

Monarch caterpillarFast forward to this past spring. When the weather started warming up, I noticed more pollinators busy in the garden collecting nectar from the early blooming plants. THEN, I noticed the number of butterflies that were enjoying my garden. Oh my gosh, for several weeks, I would go out into the garden and literally feel like I was in a butterfly house at a botanical garden! The butterflies swarmed around me as I worked in the beds. It made my heart so happy! I wish I had made a video, but I was living in the moment. There were different swallowtails, gulf fritillaries, skippers, hairstreaks, Eastern tailed-blues, sulfurs, American painted ladies, viceroys, buckeyes, and some I did not recognize. I enjoyed their presence immensely. Even though that period was totally glorious, I still have good numbers of the winged beauties visiting daily. 

Gulf fritillary on buttonbush flowerMy granddaughter and I enjoyed raising swallowtail and gulf fritillary caterpillars this summer. We  released 47 swallowtails and nine fritillaries. The swallowtails slowed down after having eaten every morsel of parsley, dill, and fennel in my garden. I saw more fritillaries at that time of the season as they voraciously attacked the passionvine. By the end of the summer, those vines were leafless, but that’s fine with me. I know they will be back next year to provide for the new generations.

I also need to mention the bees. They have also immensely enjoyed the bounty in the garden. Earlier in the season, my granddaughter and I stood under the Vitex trees while they were blooming and listened to the buzzing. The trees were alive with movement and sound! Even though the Vitex agnus-castus is not native to our country, it is still welcome in my garden for the amount of nectar it provides for the winged visitors.

Bee on Echinacea flowerThough just about over, this has been a spectacular gardening season. I truly believe that each of us can make a difference right where we are. The effort is so worth it!

It is easy to get your garden to be a certified GreenBridges™ garden.

Well, Well, What Do We Have Here? A Tale of Two Acorus Species

by Erin Holden

Tall, thin green leaves with a whitish-greenish spadixWhile doing research for a presentation on herbal uses of native plants, I decided to look more into a plant I’d learned about in herb school, sweet flag (Acorus calamus). This strongly aromatic aquatic plant has long been my favorite warming digestive bitter for those times when I overindulge in a huge meal (I’m looking at you, Thanksgiving). The flavor is warm, pungent, bitter, and spicy in a black-peppery way – the flavor sort of fills up your mouth and is warm all the way down to your stomach. But as I dug deeper into the research, I discovered I’d been wrong all this time about the origin of the Acorus species I’d been using. It turns out that A. calamus is native to Europe, temperate India, and the Himalayan region, while the native species is A. americanus (also called sweet flag), although the two species look so similar that even some scientists are unsure of which species they’ve studied and reported on. There still isn’t much consensus among taxonomists as to what differentiates these two – some even classify them as the same species (Boufford,1993; eFloras, 2008). Let’s take a deeper look at the similarities and differences between these two plants. 

There are many common names for sweet flag from all over the world (Daglan, 2014), many of which describe either the flavor of the root (like bitter, sweet, pepper) or its watery habitat:

Muskrat_eating_plant Linda Tanner via wikimediaAbenaki: mokwaswaskw (muskrat plant)

Ayurvedic Tradition: vacha 

Cheyenne: wi’ukh is e’evo (bitter medicine) 

Chinese Medicine: shui chang pú (watery flourishing weed)

English: sweet flag, calamus 

Hudson Bay Cree: pow-e-men-arctic (fire or bitter pepper root) 

Penobscot and Nanticoke: muskrat root

Micmac: ig gig’wesukwul (muskrat root)  

Pawnee: kahtsha itu (medicine lying in water) 

Many Native American names connect Acorus with muskrats. According to Sue Thompson’s dissertation on Acorus (as reported by Daglin, 2014): 

There seems to be “a closely linked ecological relationship between Native Americans trapping muskrats and using Acorus, muskrats eating Acorus, and Acorus. Muskrat feeding habits may in part be responsible for the dispersal of Acorus, and Native Americans may have intentionally planted Acorus both for their own medicinal use and to ensure food for the muskrat, which was economically valuable to them (Morgan 1980). Thus, the many Native American names for Acorus, which involve muskrat as a root word, may reflect an important economic and ecological relationship among man, plants, and other wildlife.”

A border planting of tall, thin green Acorus calamus leavesBoth species are perennial, grow in zones 4 to 10, have 1’–3’ tall iris-like leaves, and can spread 1’–2’. They bloom April through June, and like full sun to part shade. The inflorescence is a green spadix with no spathe (a spathe is a hood-like structure, like the white part of a peace lily). Both A. americanus and A. calamus are freshwater aquatic plants that grow in medium to wet soil and can grow in up to nine inches of water. They’re both easily propagated by root/rhizome divisions in the spring. Since they are aquatic plants, they can be used in water gardens, ponds, or rain gardens. They can also grow in regular garden beds as long as they get adequate water, so they’re very versatile if you’re looking for tall, straight leaves (Missouri Botanical Garden, 2022).

Although the two species look very much alike, there are some subtle differences you can use to tell them apart. A. calamus has leaves with one prominent vein and undulate (wavy) margins, does not produce fruit, and will “appear to have a shriveled ovary” in late summer, whereas A. americanus has leaves with two to six veins and smooth margins, produces small green berries, and has swelling ovaries in late summer (Dalgin, 2014).

There are also some unseen differences between the two. It turns out that A. americanus is a fertile diploid species and contains almost no phenylpropanoids, a chemical family whose members play a role in the flavors and aromas of cinnamon, cloves, nutmeg, and sassafras. A. calamus is a (mostly) sterile triploid (there are some populations of a fertile diploid phenotype in Asia that are morphologically distinct from the North American A. americanus). In addition, 13% of its volatile oil fraction is made up of those phenylpropanoids, one of which is β-asarone.

Botanical illustration of Acorus calamusThis chemical distinction is important, because β-asarone has demonstrated procarcinogenic tendencies (meaning it could metabolize into a cancer causing compound), and the FDA has banned the use of “calamus, calamus oil, or extract of oil in food,” although these studies used high levels of isolated β-asarone and not “suggested doses of the whole plant in terms of mg/kg of body weight” that an herbalist would recommend. However, since A. americanus has little to no β-asarone, it’s been suggested that this species is safe to consume (Dalgin, 2014).

Sweet flag is an important plant for many native peoples. One writer said it is “considered so sacred [to the Cheyenne] that only qualified Sundance priests [can] collect it,” and it “may be the most important herb in Penobscot pharmacology” (Dalgin, 2014). 

Historically, the Dakota used a paste on their faces to “instill fearlessness and provide stamina” in battle and chewed the rhizomes to enhance endurance “during the wars of the 20th century” (Dalgin, 2014). 

Other uses for the plant include: colds, flu, and sore throat; as a tonic; for intestinal pain and as a carminative (dispels gas); as a stimulant when tired; toothache; an analgesic for muscle cramps/spasm; and in ceremonial/religious rituals.

Tall, thin leaves of Acorus americanus growing along the bank of a streamColonists also used Acorus, and Eclectic physicians (doctors in the 1800s) incorporated it into their materia medica (list of medicinal substances). Eventually, it made its way into the first edition of the  Dispensatory of the United States in 1833 (Osol et al, 1833), which cataloged drugs used by U.S. pharmacists at the time. These groups used it pretty much the same way that Native Americans use it: as a carminative, for weak digestion and flatulent colic, as a sialagogue (stimulates saliva production) and as “breath perfume,” a warming aromatic bitter, and externally for ulcers that wouldn’t heal (Dalgin, 2014). 

Some modern herbalists who use both species say that, because of its higher volatile oil content, A. calamus targets the gastrointestinal system more specifically, while A. americanus has a “more balanced” action on the whole body—working equally on the gastrointestinal and nervous system, as an expectorant (which helps clear gunk from the lungs), spasmolytic (calms spasms), and antitussive (Daglin, 2014).

Now that I know about A. americanus and its different effects on the body, I’m interested in experimenting with the two species. I’ve also planted it out in the Native American bed in the National Herb Garden. I wonder if we should also invest in a muskrat.

400-Year Old Seeds, Nuts, and Other Artifacts—Archaeological Plant Finds From Jamestown, Virginia

By Leah Stricker

Did you know that seeds, nuts, and even leaves can survive in the ground for many years, even millennia? Paleoethnobotany, the study of archaeologically recovered plants and plant elements, can tell us many things about how humans have interacted with plants throughout history. Archaeobotanists seek to answer questions like: 

“What were the people of this culture eating?” 

“How were plants harvested?” 

“Were seeds and nuts being stored in specific places on a site?” 

“How were meals prepared?” 

“What was the role of plants in medicinal practices?”  

“Which types of plants were used as construction material, fuel, or cooking fires?”

“How did this plant come to be domesticated?”

Of course, there are numerous other research avenues that archaeobotanists study, but the above questions are some of those that archaeologists working at the site of America’s first permanent English colony, Jamestown, have pondered as they have recovered amazing finds from the site. The Jamestown Rediscovery archaeological project is an ongoing archaeological investigation of 22.5 acres of Jamestown Island in Virginia. The land was occupied by various Virginia Indian groups (see Note) prior to the arrival of the English and other Europeans. By 1607, the Powhatan tribe had become the most powerful group in the region, and they accessed the island seasonally. Wahunsenacawh, the chief whom the English called Powhatan, had centralized power from a number of individual groups, and he ruled from the village of Werowocomoco, a site not far from what became James Fort. Archaeological work at Jamestown indicates that there was much interaction between these two groups during the fort period (ca. 1607-1624), both collaborative and destructive. The botanical remains currently under investigation support finds like Virginia Indian-produced ceramics, shell beads, and locally made bone and stone tools, including over 400 projectile points, highlighting this volatile relationship. 

Recent botanical work at Jamestown Rediscovery was initiated thanks to funding from the Surrey Skiffes Creek Curation, Conservation, and Research Collection Plan. An ambitious project is underway that includes many facets, hopefully to be covered in future posts! This blog will focus on some of the recently identified and cataloged macrobotanical material, or plant artifacts that can be seen with the naked eye. These seeds, nuts, and other plant elements have survived for so long, because they have been preserved in one of two ways. If the seeds or other plant parts were burned, they became carbonized material instead of organic. They are no longer subject to microbial activity, and they will survive as tiny artifacts for a very long time. Other seeds and plant parts are preserved, because they were deposited and found in waterlogged environments. Similar to a shipwreck, if organic items like seeds or wood are waterlogged, microbes that need oxygen to survive are not present to break down the material.

At the beginning of this project, only a few formal archaeobotanical analyses had taken place using samples from Jamestown. These began to highlight the use of local plants, and perhaps the most notably recovered evidence from only three tiny seeds dating to ca. 1610–1617, the presence of tobacco in seventeenth-century Virginia.

This find confirmed what researchers had investigated through historical documentation. Ralph Hamor, Secretary of Virginia, recorded in 1612 that John Rolfe began experimenting with plantings of tobacco seeds he had gathered in the Caribbean. While there was a local variety of tobacco (Nicotiana rustica) already growing in Virginia, it was considered too strong and bitter tasting by the English. Rolfe had imported and developed Nicotiana tabaccum, the tobacco variety that became the primary export from Virginia from the seventeenth century until the mid-2000s. 

The botanical finds from Jamestown analyzed and reported on by professional archaeobotanists have now been cataloged into Jamestown’s digital database system. This allows curators to understand the assemblage of botanical material on the whole instead of within the individual reports. Other finds, recovered by archaeologists during regular excavation and screening practices on the site, have also been cataloged, and their species identified, when possible. This data shows us some intriguing information. 

1,779 seeds have been found on the site recovered by archaeologists and analyzed by archaeobotanical experts. Only 317 of these are unidentified. Of the others, over 30 species are represented, overwhelmingly locally found varieties. Some of the most commonly represented species include Cucurbita sp. (pumpkin or squash), Passiflora incarnata (passionflower), Diospyros virginiana (persimmon), Vitis sp. (grape), Vaccinium sp. (blueberry), and Zea mays (corn).

5,155 nut shells have been recovered from the site. Only 93 are unidentified. Of the others, only six species are represented. The nut finds are almost entirely hickory and black walnut, both locally available species. Only a small number of acorns (Quercus sp.) have been recovered

Other plant parts, including grape vines, leaves, pumpkin rind, pine cones, and many wood fragments—both cut, perhaps, from construction of the palisade walls or early mud and stud structures, and naturally occurring woods, like twigs—build a bigger picture of the types of foods consumed and other ways in which plants were being used at Jamestown 400 years ago.

The assemblage indicates that the colonists were consuming locally available fruits and nuts, pumpkin or squash, and corn. The colonists, more than once, wrote that supplies sent from England were spoiled or full of worms. They would have needed to supplement their diet with foods they could find locally. Corn was written about as a food, but perhaps more often, corn was referenced as a resource that was taken or given, depending on the political nature of the day.

Many of these species are mentioned by the colonists in their own records. The grape seeds and vine (Vitis sp.) may have been part of the first attempts to make Virginia wine. John Smith records these early efforts but indicates that the product was not as good as what was available in Europe at the time. However, in August, 1619, the newly established Virginia House of Burgesses codified grape production by requiring households to plant and cultivate at least 10 grape vines yearly.

Passiflora sp. seeds

Smith also wrote about a fruit that the inhabitants call Maracocks [was a]…pleasant wholesome fruit much like a lemon.” Here, he is describing the fruit of the purple passionflower or maypop (Passiflora incarnata), a species related to tropical passionfruits (Passiflora edulis, P. ligularis). 

It is not known whether the English would have prepared the hickory nuts in this way, but Smith also records pawcohiscora, or hickory milk, as a substantial beverage consumed by the Virginia Indians. The nuts were ground into small pieces and then steeped in water, not dissimilar from today’s almond, soy, and oat milks!

Hickory nuts (Carya sp.)

Although many of us learn about the “three sisters”—corn, beans, and squash—being the predominant diet of many Native American tribal groups, this does not appear to have been the case, at least at James Fort. Beans are represented by only two seeds in the assemblage. This could be due to the nature of food preparation and preservation of beans, but corn and squash are found in much greater numbers, and more parts of the plant have been recovered. 

More work is currently underway that will contribute to this initial data, continuing to build upon our knowledge of plants and how they were used in seventeenth-century Virginia. Please join us at Historic Jamestowne and see archaeology in action! We are open seven days a week and would love to share our finds with you. Learn more at https://historicjamestowne.org/.

Author’s Note: Jamestown Rediscovery uses the term “Virginia Indian,” because we’ve been told that is what the tribes (at least the individuals we have relationships with) call themselves. I am sure that there is a wide variety, even amongst Virginia tribal members as to preferences, but that is what we go with institutionally.

Olbrich Botanical Gardens’ Indigenous Garden

by Erin Presley, Olbrich Botanical Gardens Horticulturist

A narrow stone path through tall squash, corn, and milkweed, with a rustic sapling trellis.Olbrich Botanical Gardens is a 16-acre, free admission public garden in Madison, Wisconsin, in the heart of the ancestral lands of the Ho-Chunk people. The Ho-Chunk, or “People of the Sacred Voice” historically lived in southern Wisconsin, from the far southwestern corner of the state along the Mississippi River nearly up to Green Bay. This is fertile land with rolling hills and scenic bluffs where the Ho-Chunk lived in permanent villages. In fact, their oral tradition simply states, “We have always been here.” 

The area around Madison, known as Dejope or “Four Lakes,” is especially significant for the Ho-Chunk because of its abundant fresh water and resources. This land proved equally attractive to white settlers, and the Ho-Chunk were forcibly removed and Madison’s extensive lakeshore was quickly developed. In the early 1900s, Madison attorney and philanthropist Michael B. Olbrich recognized how private development would soon limit everyday people’s access to the lakes, and in 1921, he purchased over half a mile of Lake Monona shoreline property. He envisioned a sweeping park with gardens, a respite from busy workaday life, allowing everyone to be nourished by “something of the grace and beauty that nature intended us all to share.” Over the decades, additional property was purchased and consolidated within the city of Madison’s park system, and the first gardens were developed starting in the 1950s.    

A group of people in a garden listening to a presentation.Especially in Olbrich’s Herb Garden, it’s vitally important that we grow, show, and interpret plants that all types of people identify with. Herb lovers know that edible plants can act as a universal language, uniting people and making them feel at home across cultural borders. In this spirit, the Herb Garden has hosted many creative collaborative gardens over the years. Most recently, an Indian-style garden created with owners of an Ayurvedic spa oozed tropical flair with ginger and turmeric, eggplant, bitter melon, and elephant ears. 

Our partnership with Ho-Chunk tribal members began in 2020 as we brainstormed with Indigenous chefs and food activists, community organizers, and university professionals and students to envision an interactive Indigenous Garden. A walk through the “Three Sisters Living Tunnel” would invite guests to immerse themselves in dangling beans and towering corn and sunflowers. An integral part of the project would involve fun activities to draw in community members and give everyone a taste of Ho-Chunk culture.

We started with a literal “taste” when we hosted two milkweed soup samplings in summer 2021. Not many people know that the unopened flower buds of common milkweed, Asclepias syriaca, are edible! Ho-Chunk people celebrate them as a seasonal food known as mahic (maw-HEENCH), collected in bud before they open and turn pink, and incorporated into a brothy soup with green beans, ham or bacon (optional), and, arguably, the best part—tiny dumplings. 

Our interns foraged for milkweed buds, carefully scouting for and avoiding buds that already had tiny monarch eggs clinging to them. Once picked, the buds are soaked in salt water to clean them and to leach some of the milky latex before making the soup (see recipe below). The sample sessions were a hit with over 300 people served and great conversations wafting through the garden! A woman told us how she missed the sound of the Ho-Chunk language since her husband of many years, a Ho-Chunk man, had passed, and came hoping to hear the language spoken. A veteran related his visit to France to honor the graves of Ho-Chunk soldiers he had fought with. And, a 20-something Ho-Chunk guy from the neighborhood popped in just saying, “Hey, cool, I saw on Facebook you were serving mahic!” 

A garden sign with the English and Hoocak words for various plants.We also wanted to highlight the endangered Ho-Chunk language, since there are only 200 fluent speakers and only 50 are the older people who grew up speaking Ho-Chunk. At Olbrich, we are lucky to have on our staff Rita Peters, a 24-year-old college student of Ho-Chunk and Menomonee descent. Rita, known as Xoropasaignga (hodo-pa-SIGN-ga) or Bald Eagle Woman, is at the heart of the Indigenous Garden. She does everything from sowing seeds and harvesting sweetgrass to developing events and educational seminars. Rita worked with her aunt, a language apprentice, to create bilingual signage that even links to a YouTube recording of the words being spoken aloud. Here is the link to the video: Ho-Chunk language plant name recording from Olbrich YouTube channel

We had a hot summer, so with occasional irrigation, the garden grew to unimagined heights! The sunflowers topped out at 16 feet, with Ho-Chunk red flint corn—sourced from the Ho-Chunk Department of Natural Resources—not far behind. As harvest season approached, we planned for our fall celebration, a drop-in sweetgrass braiding activity. 

Sweetgrass, Hierochloe odorata, is a fine textured, running grass that likes moist conditions in full sun. It is difficult to contain in most garden situations, so commercial growers or hobbyists typically grow it in raised beds, but at Olbrich, we have a large colony that inhabits our rain garden. The bluish green leaf blades grow to about 12 inches long by mid-June and carry an intoxicating fragrance reminiscent of vanilla. The grass is harvested and dried, then made into baskets or braids. Sweetgrass, known as cemanasge (CHAY-ma-nas-gay), is used ceremonially in Native cultures, but it is also appropriate for anyone to carry in a more everyday fashion. A sweetgrass braid is always made with good intention and then can be carried in any place that benefits from an infusion of positive energy, protection, and fragrance! So, we were able to teach people to make their own braid and also to show off the fruits of our harvest. 

Two women with large black containers full of picked sweetgrass blades.As winter approached, we carefully saved seeds for the Indigenous Garden in 2022. Our milkweed soup day in early June attracted more than 330 guests! This year we are extending the Garden’s reach by collaborating with Ho-Chunk Gaming Madison, the biggest employer of Indigenous people in our area. We hope that partnerships like these will create an ever-growing network as Olbrich continues to focus our efforts on ensuring that everyone feels at home in these beautiful gardens here in Dejope.

MILKWEED SOUP:

Ho-Chunk people celebrate the foraging season for common milkweed flower buds, known as mahic in the Ho-Chunk language. The mahic is cooked up into a delicious brothy soup with other vegetables and tiny dumplings!

Prep the common milkweed (Asclepias syriaca):

Pick milkweed flower buds prior to flowering before they turn pink, usually around mid-late June. Once they turn pink they become bitter. Only take about one fourth of the buds to leave plenty for butterflies. You can use the buds and the tiny top set of leaves.  Wash well, then soak in salted water for at least half an hour, rinse, and drain.  Milkweed can be frozen for use later in the year. 

Prepare the soup:

A woman ladling green milkweed buds into a stainless steel colander.Use equal parts of water or broth and milkweed flower buds.  You can add other vegetables (green beans, corn, carrots) or ham/bacon.  Bring broth to a boil and add milkweed or other veggies.  Simmer for 30-40 minutes until milkweed and veggies are tender.

Dumplings:

Dumplings or gnocchi are a fun addition!  Small dumplings can be made with a pinch of water mixed with a pinch of flour and rolled into a small dumpling about the size of a fingernail.  Toss individual dumplings into the soup as it simmers and cook 20 minutes until the middle of the dumpling is cooked.

The Least I Can Say about Texas’ Native Bees

by Vicki Blachman, South Central District Member at Large

Honey bee on a yellow flowerThere are over 20,000 bee species in the world.  Of those, close to 4,500 are considered native to the U.S., and up to 1000 are native to Texas (I typically say “over 800”). They’re currently classified into seven families, of which six are represented in Texas. Our native bees range in size from nearly an inch long down to smaller than a peppercorn. I’ve tried to limit the scope of this article to the least I can say given that “the native bees of Texas” is a broad topic well suited to the size of our state.

As for that iconic golden yellow and black striped honey maker, the honey bee (Apis mellifera) is non-native but well established. As described by Michael Engle in 2009, it also appears to have at least one extinct ancestor (A. nearctica) that lived in North America 14 million years ago. Our challenge is that those hairy-eyed honey bees get all the love, and only recently have natives been recognized for their intrinsic value to local biomes and as the workhorses they are. Their PR needs our help.  

Bumblebee on a pink flowerHow many people even know native bees exist? They’ve pollinated every single flowering plant in North America until the 1600s when the honey bee was imported. They’re considered at least three times as effective as honey bees for pollination. Some pollinate plants that honey bees can’t, or pollinate certain crops up to 20 times more effectively. Some, like the bumble bee, are capable of buzz pollination, a technique that honey bees lack. The takeaway? Our native bees have co-evolved over time with native plants to be mutually beneficial and mutually dependent – lose one and the other will be lost as well.   

The terms “native” and “solitary” are often used interchangeably, but not all native bees are solitary, nor are all solitary bees native.  A solitary bee will mate, deposit and provision her eggs, then continue laying eggs until her death four to eight weeks after her own emergence.  Those eggs are left alone to grow and pupate, before emerging the following spring or early summer to repeat the cycle all over again.  It’s often said each solitary bee is her own queen.

By contrast, our native bumble bees are said to be social or semi-social, having the presence of two generations in a single nest at the same time.  Honeybees are called eusocial, or “true” social, due to multiple generations of individuals present, each individual having a specific role to play in the collective hive.

There are solitary bees that are non-native, bees and bee products having been imported freely until a 1922 Honey Bee Importation Law was passed. But that legislation applies to honey bees; solitary bees, which do not produce honey, continue to be imported for research and subsequent commercial use. For example, hornfaced bees (Osmia cornifrons) were first imported from Japan to Utah in 1965, but did not survive. In 1976, they were imported again into Maryland where they still thrive in a climate more like that of their home in central Japan.  The delightfully named shaggy fuzzyfoot bee (Anthophora pilipes villosula) even more recently has been imported from Japan as a managed species for commercial blueberry and other fruit pollination.

Green hollow stem of Oenanthe crocataSome solitary bees will form aggregations where nesting conditions are favorable. While a large number of individuals may be found using the site, only a very few species are actually communal, meaning they actively help each other. Dependent on their environment, the family Halictidae even has the unusual ability to switch between being social or solitary!  

The vast majority of native bees are ground nesting.  Some make cells of mud, bits of leaves or petals, resin, hairy plant fibers, wood dust, cellophane-like secretions applied with their tongues, or silk-like secretions from thoracic glands. These are placed in tunnels in the ground, abandoned rodent burrows, hollow reeds, bamboo, logs, pithy stems, softwood structures, and even holes in bricks or other man-made items such as hand tools and equipment.

Greenish halictid bee on a purple flowerWhile man-made bee houses may have benefits, in order to avoid predation and reduce susceptibility to disease they should be scattered about the site rather than clustered together.  Bee houses should have a guard of chicken wire, or other material with bee sized holes, across the opening to prevent predation by birds. The openings should face the sun in the morning and have protection from rain and insulation from extreme cold if they’re not placed inside to overwinter.  Under the Texas Death Star, it can also be beneficial to have plants growing nearby that provide afternoon shade. Habitats should also include a source of moisture and shelter from wind.  In the fall, “leave the leaves”, as well as stems and grasses, for shelter.

In closing, I repeat the takeaway I’m certain many of you already knew.  Our native bees have co-evolved over time with native plants to be mutually beneficial and mutually dependent – lose one and the other will be lost as well.

Gather Ye Redbuds While Ye May – A Colorful Harbinger of Spring…and Edible, Too!

by Karen Cottingham

Eastern_Redbud_by Dan Keck via wikimediaHere in Texas, there’s a saying: “We have two seasons – summer and winter.” That’s not quite true; but if you’re not paying attention, spring can slip right past. And the last thing I want is to miss a single day of our glorious, but ephemeral, spring. 

The nights here are still cold – sometimes approaching freezing – but the robins have arrived, so I know springtime is near. It’s time to listen for a hushed prelude to seasonal change, time to look for intimations of life beginning to stir. Every few days, this calls for a visit to the two redbud trees in my Houston neighborhood to check the trunks and bare branches for any evidence of tiny pink flowers. Nothing to see for weeks on end; then suddenly, here they are – scattered crimson buds emerging straight from the furrowed bark, swelling with life, and some already unfolding their delicate pink wings. In a week or so, the branches will be covered with a dazzling display of vibrant spring color. Heart-shaped leaves of bronze, crimson, or vivid chartreuse will soon follow and add to the brilliant Eastern redbud by Melissa McMasters via wikimediaspectacle. 

Taking a look at the distribution map of our native redbuds, a similar burst of color might announce spring’s arrival for many of our HSA members. North American redbuds fall into two groupings, each with a number of regional varieties – Cercis canadensis, or Eastern redbud, and Cercis orbiculata, the Western redbud group. Several additional redbuds are native to Southern Europe, the Mediterranean region, and central Asia; collectively, these small leguminous trees make up the entire Cercis genus.

Many of you living in redbud’s distribution may still be snowed in or are impatiently waiting for the ground to thaw so you can prepare your garden for planting. If you’re feeling restless, just imagine the anxiety of previous generations reliant on early crops to replenish their dwindling winter stores. And then imagine their relief and delight to see the first signs of the approaching spring.

Many crop-growing Native Americans considered the redbud just this sort of “seasonal indicator,” a long-awaited sign that fresh food would soon be plentiful. For some, the vibrant blossoms were even believed to hasten the arrival of warm weather. Members of the Kiowa tribe, for example, decorated their dwellings with redbud wreaths and twigs to help “drive out the spirit of winter.” 

Eastern redbud in full bloom with small pink blossomsWhile its ability to awaken a slumbering spring makes a lovely story, experience also proved that a blooming redbud can be dangerously misleading. According to Cherokee historian David Cornsilk, the Eastern redbud is known as Da-yi-go-gi, or “Liar,” in the Cherokee language. Don’t be deceived, the elders warn, by the Liar, the first tree to blossom in the spring. Da-yi-go-gi may put on a dazzling display against the dun and drab forest background, but it’s not always a reliable signal that winter is over. If precious seeds were planted based on the false promise of the blooming redbud, the tender plants might well be lost to a later hard freeze. It’s better to resist, for a while longer, the exuberance of Da-yi-go-gi.

Appalachian folklore also warns against naively trusting the early blooming redbud; a “redbud winter” refers to the cold snap that frequently occurs just after the redbuds bloom. 

As pioneers moved into the Appalachian Mountains, the native redbud trees played another important “indicator” role. Much of the soil there is acidic and too poor to sustain crops. Settlers soon learned that redbuds growing in a “cove” or “draw” indicated a limestone-rich basic soil suitable for successful farming.

Eastern_redbud_fruit_SEWilco via wikimediaNative Americans, along with the early settlers, also found ways for redbud to supplement their supply of food. Flowers, newly emerged leaves, young seed pods, and mature seeds are all edible. Even the twigs have a place in food preparation, being used so often to season game in southern Appalachia that the trees there are called “spicewood.” Traditionally, the flowers are eaten straight off the tree, but they have also been used for salad garnishes, teas, jellies, and pie fillings. Peter Kalm, the American agent of Linnaeus, called redbud the “sallad tree,” because its flowers were so often eaten in salads. 

Knowing this, I was thrilled to reach up, pick a tiny flower, inhale deeply, and pop it into my mouth. I’d been looking forward to this moment for months since I first read that redbud blossoms are not only edible, but are also delicious. The little flower emitted a strong floral fragrance that reminded me of honey. It was delightfully crunchy; floral, but in an out-of-focus, unrecognizable way; and sweet with a tangy lemony taste.

Encouraged, I decided to try an unopened bud, and was instantly propelled into my own Remembrance of Things Past moment. The flavor sensation of that little bud was identical to my childhood experience of munching on green peas picked fresh from the field! 

At first, this might sound strange, but it actually makes sense. The species Cercis canadensis belongs to the botanical family Fabaceae, making it a close relative of beans, peas, peanuts, tamarind, and other legumes.

The flowers are also rich in anthocyanins, the antioxidant pigments that give them their magenta/fuchsia color.

If you’re lucky enough to have your own tree, here are a few ways to add redbud surprises to your spring menu (links to recipes follow):

Fresh redbud flowers make a vibrant addition to salads, but also to cakes, quick breads, crackers, muffins, and even pancakes. Pickled buds can be used like capers to garnish a salad, but even better, the rosy-red pickling vinegar can be used for dressings or vinegar-based beverages. There are plenty of recipes on the internet for redbud flower jelly, and it is even possible to crystallize the flowers for a beautiful dessert embellishment. 

One of my favorite recipe ideas is for a cucumber, cream cheese, and redbud flower-filled tea sandwich. Imagine serving that for a springtime “Afternoon Tea!” You could even brew a redbud tisane, adding a bit of lemon to bring out the fuchsia color. A simple syrup of infused redbud flowers makes a lovely floral sweetener for cocktails, herbal waters, or lemonade. And don’t forget to add a redbud cluster as a garnish!

For the devoted forager with access to sassafras, here’s another idea – a goat cheese and coconut milk tart flavored with redbud flowers and newly emerged sassafras leaves. 

And why not really celebrate the arrival of spring by adding a few crunchy pink flowers to a spring roll? Sprinkle the flowers on the rice paper wrapper first so they show in the finished roll, then add other foraged flowers and greens, perhaps some shrimp or fish, and serve with a spicy peanut sauce.

The flowering period of redbuds is brief; and in a few weeks, the tree will completely leaf out and start producing seed pods. Supposedly the young leaves taste rather like grass, and the young seed pods taste like snow peas or beans. Either could be added to a stir fry, but I probably won’t try that. As one writer delicately puts it, “The high fiber content may cause some unintended and unwanted digestive consequences.”

The Navajo were said to bury the mature pods in the coals of a fire and eat the roasted seeds. I’m not sure how they would taste, but as far as survival foods go, redbud seeds, at 22-27% protein and 7-8% fat, have excellent nutritional value. The seeds are also rich in antioxidants and the essential fatty acids linoleic and alpha-linolenic acid.

Quercetin, an important antioxidant flavonoid, was actually isolated for the first time from the pods of Cercis canadensis.

But that’s not all – redbud bark is rich in therapeutic tannins and is an important medicine for several Native American tribes. Infusions of the bark are extensively used for respiratory congestion, as a cough suppressant, and to treat diarrhea and vomiting. 

In “Lenape Indian Medicines,” a compilation of the plant medicines used by the Lenape, or Delaware, tribe, Glenn McCartlin describes the remedy for vomiting used by his grandmother, Minnie Fouts: “Take six 1-1/2 ft Box Elder limbs that are pointing east. Scrape limbs starting from the end. And take two limbs from Redbud tree, and put in a pan with some cold water and drink it every little while until it quits.” I don’t know about box elder limbs, but a tannin-rich infusion of redbud bark might well have been sufficiently astringent to relieve nausea. 

And for those who suffer from depression in the dark time of the year, the traditional healers in the Ozarks prepare a tea from redbud bark that flushes out the “winter blues.” 

We tend to think of redbud as a beautiful and welcoming harbinger of spring, but it’s actually so much more – a valuable medicine and important source of nutrition, and a lively and tasty addition to your spring menus. I’m reminded of wild-food advocate Euell Gibbons challenging his TV viewers in the 1970s with what seemed to be a preposterous question, “Ever eat a pine tree?” He paused slightly, and then explained to the shocked viewers, “Many parts are edible.” I think he would have loved the colorful and edible redbud! 

I hope you enjoy it as well.
