Chamaecytisus supinus

Chamaecytisus supinus, commonly known as clustered broom or dwarf broom, is a small deciduous shrub in the family Fabaceae native to central and south-eastern Europe, from the Pyrenees through the Alps, the Carpathians, and the Balkans, where it grows in open dry woodland, scrub margins, calcareous grasslands, and rocky hillsides. The plant forms a low-spreading or weakly ascending bush 20 to 60 centimetres tall with much-branched, silky-hairy young shoots that become glabrous and somewhat woody with age. Leaves are alternate, trifoliate with elliptic to obovate leaflets 1 to 3 centimetres long, soft-hairy on both surfaces especially when young, on short petioles. Flowers are large for the plant's size, 2 to 3 centimetres long, papilionaceous, bright golden yellow, borne in dense terminal heads of three to twelve atop the current year's shoots in summer and again in autumn from leaf axils on older wood. The calyx is tubular and densely silky. The fruit is a flattened oblong pod 2 to 3 centimetres long, hairy, blackening when ripe and splitting to release several smooth seeds.
