Acacia implexa – Lightwood, Hickory Wattle

Size: 200L
Sale price$1,100.00

The Acacia implexa – Lightwood is a fast-growing, medium-sized evergreen native tree (8–15m H × 4–6m W) with a slender upright form and light green, curved phyllodes. It looks excellent in open native landscapes, rural driveways, and revegetation corridors where height, structure, and ecological function are key. Pale yellow, lightly fragrant flowers appear in late summer, attracting insects and native birds.

Acacia implexa – Lightwood thrives in full sun, tolerates drought, poor soils, and seasonal dryness, and is ideal for erosion control and habitat planting. Its deep roots, nitrogen-fixing ability, and low maintenance needs make it a strong performer in low-input sites.

Recommended for council planting, rural shelterbelts, and soil improvement zones where long-term resilience is required.
