Atropa belladonna is a branching herbaceous perennial that grows to about 1.5 meters (4.9 feet) tall. The leaves are ovate and grow up to 18 cm (7 inches) long. The flowers are bell-shaped, dull purple with green tinges, and bloom from June to August. The berries are green when unripe and turn to a shiny black as they mature.

The berries are particularly attractive to children due to their sweet taste, but they are extremely poisonous.
