Tarchonanthus camphoratus (Wild camphor bush)

Tarchonanthus camphoratus is an attractive small tree with pleasing grey- green foliage that can withstand particularly tough conditions, making it suitable for even the most environmentally demanding situation. The extremely decorative, strongly scented panicles of woolly white seed heads cover the tree for many months giving interest for most of the year. In the wild, where the Camphor bush tends to grow in thickets, it is generally smaller and bushier than those grown as single specimens in the urban landscape or when found growing with other trees, where they can reach 9m in height and develop an interesting bent trunk. In it’s natural habitat, Tarchonanthus camphoratus is browsed by giraffe, kudu, impala and springbok.
