Scotch broom is a perennial shrub that grows on average from 3.3-9.8 ft. (1-3 m) tall, but can reach to 13 ft. (4 m). Leaves are small, alternate and compound with 3 leaflets. The leaves are often not noticeable, due to the dark green stems. The flowers are bright yellow, resemble sweet pea flowers and occur singly in axils of the leaves. Seed pods are fuzzy on the edges, 1-2 in. (2.5-5 cm) long and will explode when mature. Scotch broom is native to western and central Europe and occurs in coastal areas with mild, wet winters and well-drained soils. It was introduced into the United States as an ornamental in the early 1800s.
