Kingia

Family: Xanthorrhoeaceae
Common Name: Drumhead, Grass Tree

This single-species genus from Western Australia is a member of the grass tree family, thought to be one of the oldest still in existence. It is difficult to cultivate, slow growing and hard to transplant but, if successful, adds an exciting textural quality to a garden. It is unlikely to be available outside Australia.

Species

K. australis grows extremely slowly to around 6 m (20 ft). With age, it forms a cylin­drical-shaped trunk, topped by a tuft of 60 cm (24 in) long, needle-like leaves, resembling a grass skirt. The ball-shaped heads of creamy coloured flowers are borne singly on shortish, erect stalks, forming a circle within the leaves.

Cultivation

In the UK, this plant must be grown in a warm greenhouse or conservatory, in a large pot or tub of sandy, soil-based potting compost, which must be very well drained. It needs maximum light but shade from strong, direct sun. Outdoors grow in light, well-drained soil and full sun or light shade. Although seed germinates easily, seedlings may take many years to develop. The tree has a deep and complex root system and does not take kindly to being disturbed.
