PLANT PROFILE
The Acacia mearnsii – Black Wattle is a fast-growing, evergreen native tree (6–10m H × 4–6m W) with a dense, rounded canopy and fine-textured, dark green bipinnate foliage. It looks excellent in rural landscapes, large native gardens, or along boundary lines where fast coverage, shade, or shelter is needed. Bright yellow, ball-shaped flowers appear from late winter to early spring, attracting pollinators and adding strong seasonal contrast.
Acacia mearnsii – Black Wattle thrives in full sun to part shade and adapts to poor, dry, or degraded soils. Drought-tolerant once established and ideal for windbreaks, erosion control, reforestation, and habitat planting.
Use where rapid establishment and resilience are priorities. Best suited to larger areas—avoid in confined or formal garden spaces.
