Australian blackwood is a fast-growing evergreen timber tree that adapts to a wide range of soils and climates, thriving in full sun to light shade with moderate water. It produces attractive pale yellow flowers in spring that support pollinators, and is valued for its extremely high-quality, beautifully figured hardwood. Note that this species can become invasive outside its native Australia, so check local regulations before planting.
