Commonly known as American Black Nightshade, Small-flowered Nightshade, and Glossy Nightshade, Solanum americanum is a berry-bearing herbaceous plant. Native to tropical woods of America, New Guinea, and Australia, this plant produces toxic fruits that can be confused with other edible berries. Small-flowered Nightshade is an annual or short-leaved perennial plant that reaches 3-5 feet (1–1.5 m) in height. Its foliage is ovate in shape and can reach the size of 4 in (10) cm in length and 3 in (7 cm) in width. The plant produces inconspicuous flowers in June that are only 0.3 in (1 cm) in diameter.
