A popular attractive ornamental tree, it is a medium to large tree growing up to 8 metres, producing masses of bright golden flowers in clusters. It is also used in herbal medicine. Introduced to Australia, it has naturalised in northern, central and south-eastern Queensland, near Darwin in the north-western parts of the Northern Territory and the northern parts of Western Australia.

Whilst it is found in tropical and subtropical areas, it also grows well in dry climates, being relatively drought-tolerant. The images here are from Alice Springs in Central Australia.
