Paraserianthes lophantha, commonly called Albizia, Cape Leeuwin Wattle, Cape Wattle, Crested Wattle or plume albizia, is a fast-growing wattle tree that occurs naturally along the southwest coast of Western Australia, from Fremantle to King George Sound. It was first spread beyond southwest Australia by Baron Ferdinand von Mueller, who gave packets of P. lophantha seeds to early explorers under the assumption that if they planted the seeds at their campsites, the trees would indicate the routes they travelled.
