A common plant of disturbed site throughout nearly all of Florida. Ranges across much of the southern United States and up the west coast. Introduced in British Columbia and Manitoba.
An unarmed nightshade growing up to 1.5m (59 in.) tall, but often half that. Leaves are alternate on long petioles up to 4cm (1.6 in.) in length. The blades are 5-10cm (2 to 4 in.) long, ovate to deltoid in shape with entire or irregular wavy margins. The inflorescence has two to five flowers in an umbel on a short peduncle. The flowers are white, sometimes pale violet, and only up to 1cm (0.4 in.) wide with yellow anthers in a united cone-like structure in the center. The fruit is a berry 5-10mm (0.2 to 0.4 in.) in diameter, turning black when mature. Note that the unripe fruit is poisonous.
