Kingia australis

A slow growing plant, native to south west Western Australia, Kingias are similar to grasstrees (Xanthorrhoea) in habit, except for the flowers. They have one or more trunks, 6 to 8 metres tall, with a large tuft of grassy leaves atop. A new growing point is formed if the main trunk gets damaged. The flowers give an interesting look to the plant, as yellow-green to brown round flower heads on stalks are held above the mop of foliage.
Transplanting of mature specimens is difficult. Best results are when the plant is given a good free draining soil, and is kept moist until established.
Kingias can live for centuries, and are slow growers. They put on around 1 1/2 centimetres in growth a year, so a 6 metre specimen is old indeed!
