Acacia dealbata (Silver Wattle) is a species of Acacia, native to southeastern Australia in New South Wales, Victoria, Tasmania, and the Australian Capital Territory.

It is a fast growing evergreen tree or shrub growing up to 30 m tall, typically a pioneer species after fire. The leaves are bipinnate, glaucous blue-green to silvery grey, 1–12 cm (occasionally to 17 cm) long and 1–11 cm broad, with 6–30 pairs of pinnae, each pinna divided into 10–68 pairs of leaflets; the leaflets are 0.7–6 mm long and 0.4–1 mm broad. The flowers are produced in large racemose inflorescences made up of numerous smaller globose bright yellow flowerheads of 13–42 individual flowers. The fruit is a flattened pod 2–11.5 cm long and 6–14 mm broad, containing several seeds. Trees generally do not live longer than 30 to 40 years, after which in the wild they are succeeded by other species where bushfires are excluded.

Cultivation

Acacia dealbata is widely cultivated as an ornamental plant in warm temperate regions of the world, and is naturalised in some areas, including southwestern Western Australia, southeastern South Australia, Norfolk Island, the Mediterranean region, and California.
