Description

Cytisus hirsutus reaches on average 30–40 centimetres (12–16 in) of height, with a maximum height of about 100 centimetres (39 in). The stem is more or less ascendent, woody in the lower part, branched, with ascending annual and herbaceous branches (suffruticose) with hairs 3 millimeters long (hence the Latin name hirsutus of this species, meaning hairy). The small deciduous leaves are trifoliate, ovate to elliptic, hairy on both sides, 18–25 millimetres (0.71–0.98 in) long, with a petiole. The flowers are initially orange-yellow, then tend to be colored with reddish brown. The flowering period extends from April through June. Its legumes (seed pods) are 25–40 millimetres (0.98–1.57 in) long, very hairy and mature in late Summer.
