The is 15-60 cm tall, and is much branched. All parts of the plant contain [[solanine]], and are poisonous. The main symptom of poisoning is [[gastrointestinal irritation]].<br /> <br /> The leaves of Eastern black nightshade are triangular to elliptic. The stems are circular, and sometimes slightly hairy. The flowers are small, white, and star-shaped. They are located in small [[umbel]]s of 5-7. The flowers ripen into glossy, black [[berries]], each 10 mm in diameter and containing between 50 and 100 seeds. The fruits are ''not'' poisonous, which allows [[birds]] to eat and disperse the seeds.<br /> <br /> == Habitat ==<br /> Eastern black nightshade grows in landscapes, and most [[agriculture|crops]]. It is most likely to be found growing near crops of related species such as [[tomato]]es and [[potato]]es. It can grow on sandy and poor [[soil]], but prefers fertile and cultivated soil types. Eastern black nightshade is found principally in the [[Eastern United States]].<br /> <br /> == References ==<br /> * Richard H. Uva, Joseph C. Neal and Joseph M.
