Hakea bucculenta, commonly known as red pokers,[2] is a large shrub in the family Proteaceae endemic to Western Australia. A spectacular ornamental shrub with red or orange flowers that appear in rod-like blooms in leaf axils for an extended period from May to November.

Description

Hakea bucculenta is non-lignotuberous upright, rounded, bushy shrub that typically grows to a height of 1.5 to 4.5 metres (5 to 15 ft) but can reach as high as 7 m (23 ft). Smaller branches have irregular patches of flattened silky hairs becoming smooth at flowering. The leaves are a narrowly linear shape with a slight curve and 90 to 200 millimetres (4 to 8 in) long and 1 to 3 millimetres (0.039 to 0.118 in) wide. Each leaf has fine ribbing, conspicuous veins with an obvious mid-vein on both sides and ending with a sharp point. Each inflorescence is made up of 250 to 450 showy orange or bright red flowers in racemes up to 15 cm (6 in) long on a smooth stem 8.5–13.5 cm (3–5 in) long. Flowers appear from May to November, the main flush in spring. The pedicel is smooth and perianth a bright red. The style 18–21 mm (0.7–0.8 in) long. The woody fruit are egg-shaped 1.7–2.5 cm (0.7–1 in) long and 1–1.5 cm (0.4–0.6 in) wide. The grey smooth fruit appear in clusters of 3–16 on a long stem or attached directly onto the branch. Each fruit is divided into a thick body ending a blunt beak. The blackish or brown seeds are obliquely obovate with a length of 16 to 18 mm (0.63 to 0.71 in) and a width of 7 to 9 mm (0.28 to 0.35 in) with a single wing.[3][4][5][6][7][8][9]

Taxonomy

Hakea bucculenta was first formally described by the botanist Charles Austin Gardner in 1936 and published in the Journal of the Royal Society of Western Australia.[1] The specific epithet (bucculenta) is derived from the Latin word bucculentus meaning "with full cheeks",[10] which refers to the shape of the fruit.[3]

Distribution

Hakea bucculenta is endemic to coastal areas in the Gascoyne and Mid West regions between Shark Bay and Geraldton in Western Australia. Grows on coastal sand plain heath or mallee, roadsides verges in sandy, loam or clay-based soils.[11]

Cultivation

Hakea bucculenta is sensitive to dieback and thus difficult to keep alive in areas of high humidity. It can be successfully grafted onto Hakea salicifolia. It is most commonly propagated from seeds which germinate in about three to four weeks. Cuttings can also be used but usually have a low rate of success. It grows well in a sunny position out of the wind in well-drained soils; it will tolerate both drought and frost.[2][5]
