Solanum (Latin, solamen, solace or quieting). Solanaceae. Nightshade. A vast group of temperate and tropical herbs, shrubs and even trees, comparatively poorly represented in temperate North America, of various horticultural adaptabilities, comprising ornamental subjects and also the potato, tomato, eggplant, ground cherry or physalis, red pepper or capsicum; also medicinal plants.

Species
See text.

Solanum is a large, variable genus of annual plants and perennial plants, forbs, vines, sub-shrubs, shrubs, and small trees. They often have attractive fruit and flowers. Most are poisonous, but many bear edible fruits, leaves, or tubers, and the genus includes several cultivated species, including three major food crops:

Solanum species are used as food plants by the larvae of some Lepidoptera species - see list of Lepidoptera which feed on Solanum.

Species

Eggplant (Solanum melongena)
Forked Nightshade (Solanum sisymbriifolium)
Solanum mammosum
Solanum pseudocapsicum fruit
