wetland nightshade

Solanales > Solanaceae > Solanum tampicense Dunal
Synonym(s): aquatic soda apple

Wetland nightshade is a sprawling, semi-woody shrub that invades wetlands in Florida. The green stems are up to 15 ft. (4.6 m) long and prickly. Leaves are alternate, to 10 in. (25 cm) long, 3 in. (7 cm) wide, wavy along the margins and have prickles on the veins. The small, white flowers occur in small clusters at the leaf axils during the summer to fall. The fruits are small tomato-like berries that turn bright red when ripe. Wetland nightshade, being tolerant of full sun and full shade, can invade many types of wetland ecosystems such as cypress swamps and river edges. It is capable of forming extensive, dense stands that displace native vegetation. Wetland nightshade is native to the West Indies and Central America. It was recently, accidentally introduced into Florida.
