Description

Hakea platysperma is a single stemmed, spreading shrub to 1–2 m (3 ft 3 in – 6 ft 7 in) tall and a similar width. The branchlets and young leaves are covered with rusty coloured, flattened, smooth hairs. The thick, rigid leaves are needle-shaped, 3–15.5 cm (1.2–6.1 in) long, 1.4–3 mm (0.055–0.118 in) wide, yellowish at the base and ending with a sharp point 1–4.5 mm (0.039–0.177 in) long. Sweetly scented creamy reddish to yellow flowers appear in profusion in axillary racemes. Flowering occurs from July to October and the fruit are globose, cricket ball shaped and 4.5–7.5 cm (2–3 in) long by up to 6.5 cm (3 in) in diameter, with a smooth surface.[3][4]

Taxonomy and naming

Cricket ball hakea was first formally described in 1842 by Joseph Dalton Hooker and the description was published in his book Icones Plantarum.[5][6][7] The specific epithet (platysperma) is derived from the Ancient Greek platy - wide, and sperma - seed, referring to the large, circular fruit.[8]

Distribution and habitat

Hakea platysperma grows in sand, sandy clay and occasionally over laterite in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains and Mallee biogeographic regions of Western Australia.[7]

Conservation status

Hakea platysperma is classified as "not threatened" by the Western Australian Government.[7]

Cultivation

The main horticultural appeal of this species is the giant woody seed pods, which have been used in cut flower arrangements. H. platysperma can be grown in a sunny position in well-drained soil.[9]
