Acacia dealbata is characterized by its greyish-green foliage, differing from A. mearnsii in having prominent raised glands at the junction of each pinna pair but not between them, and from the naturalised A. decurrens by its hairy, greyish-green coloured, crowded pinnules. It apparently hybridizes with the naturalised A. baileyana.
Fast growing and sometimes cultivated. A source of gum arabic substitute.
