Hakea sericea, commonly known as bushy needlewood or silky hakea,[2] is a large shrub with a profusion of mainly white flowers from July for several months. It is endemic to eastern Australia. It has become an environmental weed in some countries.

Description

Hakea sericea is a large spreading, bushy shrub and may grow to 4 m (10 ft) and does not form a

pistil
4–7.5 mm (0.16–0.30 in) long. The needle-shaped leaves are grooved on the undersurface and up to 7 cm (3 in) long and 0.7–1.3 mm (0.03–0.05 in) wide and ending in a sharp point 1–2 mm (0.039–0.079 in) long. The leaves are moderately covered with flattened silky hairs, quickly becoming smooth. The fruit are rough and coarsely wrinkled with a network of veins on the surface, 2.5–3 cm (1–1 in) long and 2 cm (0.8 in) wide ending with a short, broad beak to 3 mm (0.12 in) long.[3][4][5][6]

Taxonomy and naming

Hakea sericea was first formally described by Heinrich Schrader and Johann Christoph Wendland in 1797 and published the description in Sertum Hannoveranum.[7] The genus Hakea is named after Baron von Hake, patron of botany in the 18th century. Sericea meaning silky, referring to the tiny hairs on young growth.[6]

Distribution and habitat

Silky hakea is found from the coast and adjacent ranges of south-eastern Queensland to south-eastern New South Wales. A frost tolerant species, grows in well-drained soil and full sun. A good habitat plant due to its prickly habit and winter flowering. It is also naturalised in

Victoria and possibly South Australia.[8]

H. sericea is an invasive weed in some areas outside Australia, specifically in South Africa, New Zealand and Portugal.[9][10]
