Brachychiton populneus, commonly known as the kurrajong, 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. The extended trunk is a water storage device for survival in a warm dry climate. The bell-shaped flowers are variable in colour (pale to pink) while the leaves vary considerably in shape. The leaves are either simple and pointed, or may be 3–9 lobed. Saplings grow from a drought and fire resistant tap-rooted tuber.Growing – plant direct into local soil based potting mix (ie your garden soil will do) or 25mm jiffy pots, keep in direct sun and keep moist.  usually takes 10-15 days to germinate transplant at 50mm high in to tall narrow pots/plastic grow tubes/bags to 150mm, the into tall grow bags (400mm).  These trees can grow to 1.5m in 12 months. 
Kurrajong will grow well in tall pots on a patio or verandah full sun with minimal care. Or transplant into the garden or paddock for a shade tree option.  Very high germination rate
