Hakea gibbosa aka Rock Needlebush

Hakea gibbosa is an evergreen shrub in the Proteaceae family. Its common names include hairy hakea and needlebush hakea. It comes from eastern New South Wales in Australia. Kew places it in the subtropical climate zone. It is not native to Britain or Ireland. Its stiff leaves and woody fruits help define its appearance.

The shrub has a bushy form with upright growth. The RHS describes plants reaching about 10 feet [3 metres]. Its listed garden height range is 8–13 feet [2.5–4 metres]. The spread is about 3–5 feet [1–1.5 metres]. Plants take 10–20 years to reach their full size. Fine hairs cover the stiff, grey-green leaves. These narrow, needle-like leaves end in sharp points. They can reach about 0.26 feet [0.08 metres] long. The foliage stays on the plant throughout the year.

Small, cream-white flowers grow in loose groups among the leaves. Each group holds between two and six flowers. They sit in the leaf axils, where leaves join stems. Woody seedpods may follow the flowers. These egg-shaped fruits reach about 0.11 feet [0.035 metres] long. The supplied species account does not state a flowering season.

Grow this shrub in full sun in a sheltered spot. A south-facing site suits the RHS guidance for British gardens. Use fertile, sandy soil with good drainage and slight acidity. The RHS also lists loam as a suitable soil type. Its H3 rating suits coastal and other mild British areas. That rating covers minimum temperatures of 23–34°F [−5 to 1°C]. In colder settings, the RHS lists greenhouse or conservatory growing. Under glass, give it full light and a free-draining mix. Use equal parts loam, sharp sand, and peat substitute or leaf mould. Apply phosphate-free feed monthly during the growing season.

The RHS suggests coastal gardens, patios, and containers as uses. It also lists the shrub for low-maintenance planting. Raise new plants from seed or semi-ripe cuttings. The RHS reports few usual pest or disease problems. However, contact can irritate skin or cause an allergic response. This warning applies to people and dogs. Wear gloves and other protection when handling it. The supplied evidence gives no food use for this species.
