Solanum

From eagle-rock.org

Solanum, the nightshades, horsenettles and relatives, are a large and diverse genus of annual and perennial plants. They grow as forbs, vines, subshrubs, shrubs, and small trees, and often have attractive fruit and flowers. The species usually most commonly called nightshade in North America and England is Solanum dulcamara, also called bittersweet and woody nightshade. Its foliage and egg-shaped red berries are poisonous, the active principle being solanine, which can cause convulsions and death if taken in large doses. The Black Nightshade (S. nigrum) is also generally considered poisonous, but its fully ripened fruit and foliage are cooked and eaten in some areas.

Most parts of the plants, especially the green parts and unripe fruit, are poisonous to humans (although not necessarily to all animals), but many species in the genus bear some edible parts, such as fruits, leaves, or tubers. Several species are cultivated, including three globally important food crops: tomato, potato, eggplant.
