Horticulture/Solanum

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: Tomatoes, Potatoes, and Eggplants.

Description
Annual, perennial, or tropical herbs or vines with alternate leaves and a watery sap. The flowers are in cymes or solitary, perfect, showy, 4-5 parted, with thick yellow anthers. Fruits are fleshy berries. Most species have a distinctive scent common to the genus.
