Scattered through the State; often persisting in and spreading from old farm sites, common along watercourses, particularly in north-eastern Victoria and Melbourne suburbs. Probably more widespread than records indicate. A declared noxious weed in Victoria (except in Melbourne metropolitan area).
The leaves and bark are used in traditional Chinese medicine, but may cause dermatitis in some people.
