Description

Eastern Black Nightshade is native to North America and is widespread in eastern Canada.

It is an annual, rarely a short-lived perennial. Stems are green or greenish purple, round or angular. Seedling leaves are usually purple underneath. Berries are 5 mm to 9 mm in diameter and contain up to 100 seeds each. It is therefore very prolific, as a single plant can easily produce up to 1000 berries.

Eastern black nightshade is found in many crops and is a particular concern for soybeans, edible beans and pea growers. All parts of eastern black nightshade are reputed to be poisonous; however, the green leaves, stems, and seeds are especially toxic. Following dry conditions, the concentration of the toxins is higher in all plant parts; toxicity also varies according to plant stage.
