This primeval-looking plant grows up to 7 m tall and is largely confined to the south-west of Western Australia. Near Perth, it grows on the eastern side of the coastal plain and in a few spots in the Darling Range. It has a similar appearance to Balga, with long, thin leaves and a trunk made of compacted leaf bases, but it is not closely related botanically. Kingia is unusual in having aerial roots, which emerge from it’s growing shoot, but then descend down to the ground underneath the leaf bases. They are not visible. Flowers occur on the end of “drumsticks” in winter and after fire.
