Brachychiton populneus, commonly known as the kurrajong,[1] is a small to medium-sized tree found naturally in Australia in a diversity of habitats from wetter coastal districts to semi-arid interiors of Victoria, New South Wales and Queensland.

Carrejun and carrejan were the indigenous names of trees in the foothills of the Blue Mountains near Sydney, and the bark was used for twine and fishing lines.

[2] The tree is drought-tolerant and the extended trunk is a water storage device for survival in a warm, dry climate.

[3] It has been introduced as an ornamental tree to south-western Australia, South Africa, Louisiana, California, Arizona and Mediterranean countries.

However, B. discolor is also referred to as the lacebark kurrajong, and bottle tree is a term commonly applied not only to other species of Brachychiton but to members of other genera around the world.
