Solanum torvum, Turkey Berry


Invasive Species: Solanum torvum, Turkey Berry

Turkey berry is a broadleaved, evergreen shrub or small tree that invades a variety of ecosystems in Florida. Plants can grow to 16 ft. (4.9 m) in height. The stems are armed with stout, straight, or lightly curved prickles. The alternate leaves are elliptical, 10 in. (25 cm) long, have prickles along the midvein, and star-shaped hairs underneath. Leaves range from unlobed to strongly lobed. The small, white flowers occur in large, branched clusters. Plants flower continuously after reaching a height of 3.3 to 4.9 ft. (1 to 1.5 m). Fruit are small, yellow berries. Although turkey berry has only been found several times in Florida, it has the potential to invade a variety of sites, both wet and dry. Once established, it can sprout from the roots, creating large thickets that could displace native vegetation. Turkey berry is found throughout the world’s tropical regions and was introduced into Florida sometime before 1900 for cultivation trials.
