A small to medium shrub which may reach 3 metres in height. Like many wattles, genistifolia has flattened stems (called Phyllodes) rather than leaves. The phyllodes are narrow and rigid, about 15-30 mm long with a sharp point. The cream or pale yellow flowers occur in globular-shaped clusters from late summer to spring. Because of its prickly nature, it is an excellent habitat plant for native birds. Great for partly shaded sites due to its showy flowers, prune for bushiness after flowering.
