Description

Silverbush is a coastal shrub or small tree to 5 m high. Leaves are 10-20 cm long, usually divided into 11 to 17 oval to circular leaflets 20-40 mm long, 10-30mm wide with woolly hairs. The pale yellow flowers are in clumps 10-15 cm long and appear during winter. They are followed by 10-18cm long seed pods containing 5-10 seeds, with the pod strongly constricted between seeds.
