Wetland nightshade (AKA aquatic soda apple) is found growing in floodplain forests of the central peninsula and Monroe County. It is native to the West Indies, Mexico, and Central America and blooms in the fall (Wunderlin, 2003).
Appearance: Straggly and sprawling prickly shrub, woody below; herbaceous above, with prickly green stems to 5 m (16 ft) long and 1.5 cm (0.5 in) in diameter.
Leaves: Alternate, simple, with petioles to 3 cm (1.5 in) long; blades longer than wide, to 25 cm (10 in) long and 7 cm (3 in) wide, with deeply round-indented (sinuate) margins, recurved or straight prickles on veins, and stellate hairs.
Flowers: Small; 3 to 11 individual flowers in stalked, branched clusters at leaf axils; petals white, mostly free (fused only at base), spreading or often recurved; stamens with yellow anthers held closely and erect in center of flower.
Fruit: A small, spherical, tomato-like berry to 1 cm (0.4 in) wide, shiny solid green turning orange then bright red at maturity, with 10 to 60 yellowish, flat-round seeds.
