Commonly known as the kurrajong, this small to medium-sized evergreen tree is native to Australia where it grows in diverse habitats.  It is member of the mallow family, Malveaceae, that also includes okra, cotton,  chocolate and hollyhock.  The trees grow 30-50′ tall and have a bottle like swelling at the base of their trunks which stores water.  The ovate green leaves are up to 3″ long, may be simple or have 3-9 lobes, and shimmer in the breeze like those of quaking aspens.  In late spring or early summer 3″ long clusters of male and female 1/2″ wide yellowish-white flowers appear on the same plant.  They lack petals but the caylx forms bell shaped perianth that is reddish inside and sometimes has dark spots on the outside.  Fertilized female flowers give way to a woody canoe-shaped dry seedpod that is 2-3″ long and can be a litter problem.  Bottle tree is tolerant of drought and partial shade, and is suitable for windbreaks, screen, street tree, and shade tree in a xeriscape.  The seedpods are attractive in dried arrangements.  The genus name, Brachychiton, is from the Greek words brachys meaning short, and chiton meaning tunic, and refers to the loose seedcoat.  The specific epithet, populneus, means similar to Populus, poplars, refering to the leaves.
