Description

Hakea verrucosa is a spreading prickly shrub growing to 0.8–2.6 m (3–9 ft) high and does not form a lignotuber. The branchlets are covered mostly in densely matted short rusty hairs. The green terete leaves are about 2–6.3 cm (0.79–2.48 in) long and 1–1.5 mm (0.039–0.059 in) wide, ending in a sharp point 1–2 mm (0.039–0.079 in) long. The leaves are smooth and have a tendency to point in one direction from the branchlet. The pendant inflorescence consists of 7-14 white, pink to red flowers in a showy profusion in axillary clusters, or on old wood. Each inflorescence is held on stalk about 3–16 mm (0.12–0.63 in) long. The pedicel 2–5.4 mm (0.079–0.213 in) long, the perianth 6–9 mm (0.24–0.35 in) long, initially a cream-white and aging to pink. The pistil 21–25 mm (0.83–0.98 in) long. Flowering occurs between May and August. The fruit are obliquely egg-shaped 2.2–3.1 cm (0.9–1 in) long and 1.2–1.4 cm (0.5–0.6 in) with blister-like protuberances, tapering to two horns 2.5–5 mm (0.098–0.197 in) long.[2][3][4]

Taxonomy and naming

Distribution and habitat

Hakea verrucosa grows in heath and low woodland on sandy-loam, near creeks, clay and gravel ranging from Jerramungup along the coast to Esperance.

Uses in horticulture
