HSA Webinar: Shedding Light on the Solanaceae: An Exploration of Our Relationship with Nightshades

by Jen Munson, HSA Education Chair

20170811_093151The nightshade family of plants sounds ominous  – how could it not with the use of the words night and shade? The official name of this family is Solanaceae, and these plants are characterized by the shape of the flower, which in some cases feature near perfect pentagrams of petals, sepals, and stamens, and in others the petals are fused to form long tubes.

The Solanaceae features nearly 90 genera and 3,000 species, including some of humanity’s most important plants. You may be surprised to learn that many of our everyday foods fall in the nightshade family. These include hot and bell peppers, potatoes, eggplant, and tomatoes. To learn more, join HSA on April 13th at 1pm EDT when National Herb Garden gardener, Erin Holden, joins us for “Shedding Light on the Solanaceae: An Exploration of Our Relationship with Nightshades.” 

Lycopersicon_esculentum_Supersweet_100_0zz by David J StangAlthough many plants in this family are edible, others are recognized for their hallucinogenic properties, use in witchcraft, and/or some level of toxicity. The toxicity comes from the level of alkaloids the plant contains, and the effects of these alkaloids are what made them useful historically. For example, thornapple (Datura stramonium) was used by religions to aid in dreams and visions. More recognizable is the mandrake (Mandragora officinarum), which was highlighted in the Harry Potter series for its role in potion making. It is surmised that the high level of alkaloids evolved out of self-preservation to prevent being consumed by animals. During our April 13th program the deep relationship between humans and members of the Solanaceae family will be further explored, from their magical uses to their application as medicine, poison, and food.
