Twoleaf Nightshade (Solanum diphyllum)
Description
Solanum diphyllum, commonly known as the twoleaf nightshade, is a species of nightshade native to the Americas. It is cultivated as an ornamental plant for its clusters of dark green round fruits that turn a bright yellow when ripe. Twoleaf nightshades are small shrubs about 1 to 2 m (3.3 to 6.6 ft) tall. The stems are smooth or sometimes slightly downy with a dark brown bark. A distinctive feature of twoleaf nightshades is that their leaves grow in pairs from a single bud, hence the name 'twoleaf'. Each pair is composed of a major and a minor leaf. Major leaves average at around 6 cm (2.4 in) long by 2 cm (0.79 in) wide and are elliptic to oblong in shape. Minor leaves are smaller and more rounded, they are 2 cm (0.79 in) long by 1 cm (0.39 in) wide on average. The leaves are a glossy dark green on the upper surface with a lighter green on the ventral side. The petioles are about 2 mm (0.079 in) in length.
