About
Acacia melanoxylon, commonly known as blackwood, Tasmanian blackwood, hickory, sally wattle, black sally or mudgerabah, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It is a tree, sometimes a shrub, with hard, fissured and somewhat scaly bark, ribbed, usually glabrous branchlets, narrowly elliptic or lance-shaped phyllodes, spherical heads of creamy pale yellow to white flowers, and strongly curved to openly coiled pods.
Where it grows
Blackwood is widespread and often common, found from the Atherton Tableland and south through the highlands of Queensland, New South Wales, the Australian Capital Territory, Victoria and Tasmania. It is also found in the Mount Lofty and Flinders Ranges in South Australia and is sometimes naturalised in Western Australia. It grows in a variety of habitats, favouring fertile valley soils and flats in mountainous areas, often and forest and cooler rainforest, sometimes in drier eucalypt forest and woodland. In Tasmania, it is often the dominant tree in forested seasonal swamps.
Uses
Indigenous Australians use many parts of A. melanoxylon for a variety of purposes. Seeds are harvested and consumed as a common bush tucker food, and leaves can be used as a soap or fishing poison. The bark is either harvested to make string or prepared as a traditional analgesic, while wood is often used to make clap sticks, spear-throwers and shields.
