"Banksia petiolaris" is one of the prostrate banksias, a group with horizontal stems and thick, leathery upright leaves. Found in sandy soils in the south coastal regions of Western Australia in the vicinity of Esperance. It is nonlignotuberous, regenerating by seed after bushfire.

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.

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
