An evergreen tree growing 5-10m high, black wattle has dark olive-green finely hairy leaves. Pale yellow or cream spherical flowers in large fragrant sprays blooming from August to September. Fruits are dark brown, finely haired pods.
Black wattle has invaded grasslands, competing with and reducing indigenous species, and reducing grazing land for wild and domestic animals.
