Acacia melanoxylon, commonly known as Australian Blackwood, is a fast-growing evergreen tree native to southeastern Australia, including Tasmania. It thrives in a variety of habitats such as coastal areas, riparian zones, and open forests, often in the company of eucalyptus. This species can reach up to 20 meters (66 feet) in height with a bole diameter of about 150 cm (59 inches). Australian Blackwood has a distinctive appearance, with dark, fissured bark and long, leathery phyllodes (leaf-like structures) instead of true leaves. The phyllodes are variable in size and shape, which contributes to the species’ adaptability. From July to December, it produces fragrant, pale yellow to nearly white flowers arranged in spherical clusters, each 5 to 10 mm in diameter, which are highly attractive to bees and other pollinators.

Australian Blackwood is valued for its dense, dark wood used in fine furniture and cabinetry, and as an ornamental tree for its lush foliage and attractive flowers. It is suitable for urban planting, as a windbreak, or for erosion control due to its extensive root system. In cultivation, it prefers full sun, medium water, and well-drained soils. While it can adapt to a range of soil types, it performs best in fertile, loamy soils. Gardeners should be aware that this species can become invasive outside its native range, and its vigorous growth may require regular pruning to maintain a desired shape.CC BY-SA 4.0
