Scientific name Banksia spinulosa Sm.

Etymology

Genus: After Sir Joseph Banks, 1743-1820, botanist who travelled with Captain Cook.

Species: From Latin, spinulosus, bearing spines, probably refers to the leaf tip of the plant originally described.

Distribution From the Atherton Tablelands in northern Queensland, almost to the Victorian border.
Native habitat Occurring in open forest or woodland on the coast and ranges on a variety of sandy or loamy soils, often from a sandstone or granite base.
Description

A medium to large shrub.

Flowering/fruiting Flowers in autumn to winter.

Location in Garden

This species and a number of cultivars can be seen in the Big Idea Garden and the Banksia Garden.

 

There are several different varieties and selected forms of the hairpin banksia, which can show indistinct differences, making their identification difficult. B. spinulosa var. spinulosa differs from B. spinulosa var. collina only in its rolled-under leaf margins. It was introduced and has been grown successfully in Britain since 1788.

The hairpin banksia is useful in the garden for planting beneath established eucalypts, and will grow well in the shade. Its dense habit makes it suitable as a screen plant.
