Hakea petiolaris
Sea urchin hakea is a Western Australian shrub or small tree, up to about 9 m, known for its spiky woody seed capsules and pale grey leaves. It is grown in gardens mainly for screening, hedging and bird-attracting flowers, and it needs full sun and well-drained soil.
Hakea petiolaris, commonly known as the sea-urchin hakea, is a shrub or small tree with cream-coloured and pink or purple flowers and woody fruit. It is endemic to the south west of Australia, occurring at the coastal plain, jarrah forest and wheatbelt regions, often at the ancient granite outcrops of Western Australia.
The species is propagated from seed, establishing itself as a large shrub, or a tree to around ten metres, the width is around two metres. The horticultural applications include use as a screening plant or hedge, or displayed as individual specimens. It is a fast growing and hardy species, frost resistant, bird attracting and has good potential as a feature plant.
Hakea petiolaris is recommended for the attractive appearance of its flowers and attraction for birds. Clusters of dullish red flowers, contrasted by white styles, are presented at the leaf axis in the austral autumn or winter. The plant is successfully grown in the urbanised sub-coastal regions of southern Australia.
Subspecies petiolaris grows in jarrah forest, usually near granite outcrops between the Darling Range and York in the Avon Wheatbelt, Jarrah Forest and Swan Coastal Plain biogeographic regions.
