The species occurs in mainly in the eastern and southern half of Australia and not in Western Australia and the Northern Territory. Reaching 10 m (35 ft) high, it bears fragrant white flowers at any time of year but particularly summer.

It is an important food plant for several species of butterflies and moths, particularly those of the genus Paralucia.
