Eastern black nightshade

An erect summer annual, reaching as much as 1-1/3 feet in height. Seedlings have cotyledons that are green on the upper surface, but distinctly purple- or maroon-tinted on the lower surface. Young leaves also remain purple- or maroon-tinted on the undersurface. Mature plants have leaves that are simple, alternate and ovate in outline. Stems are branching, round or angular, smooth or only partially hairy, and become woody with age. Flowers are star shaped, white or purple-tinged, and occur in umbel-like clusters of five to seven. Berries develop that are 5 to 12 mm in diameter, green when immature, turning purplish black at maturity.
