[edit] Description
It is a prostrate shrub with thick stems, new growth is covered with orange brown hair. The leathery leaves are upright and are the longest-lived angiosperm leaves so far recorded (up to 13 years for a single leaf!). The inflorescences are yellow and flowering is in late spring.
[edit] Cultivation
In cultivation, though somewhat resistant to dieback, it does require a well drained soil, preferably fairly sandy. It makes an attractive prostrate groundcover. It is tolerant of alkaline soils
