Acacia adunca (Wallangarra Wattle) is a small evergreen tree that is native to inland regions of Queensland, New South Wales and Victoria. The Wallangarra Wattle is a fast-growing low-maintenance native that produces yellow flowers, year-round foliage and adapts to a wide range of conditions.
Suitable for Temperate, Dry, Semi-Arid and Sub-Tropical climates.
The Wallangarra Wattle is also known as the Cascade Wattle in reference to the cascading nature of its branches.

Growth
Acacia adunca is a native tree that grows to a maximum height of up to 6 metres (20 feet) and a maximum width of roughly 3 metres (10 feet). Like most Acacia species, it has phyllodes rather than traditional leaves and these bright green phyllodes grow to around 14cm (5 inches) long and 1cm (less than half an inch) wide and finish with a long point.
A fast-growing tree, the Wallangarra Wattle can begin flowering in 2-3 years. Flowers bloom from late winter into spring, are lemon yellow in colour and hold tight in cylindrical clusters that are about 2cm (under an inch) in diameter. Seed pods follow in the Summer, which can be harvested from the tree or collected off the ground.

FACTS ABOUT ACACIA ADUNCA (Wallangarra Wattle )
There are two theories as to how the botanical term Acacia was named. The first is that it may be from a Greek word meaning to sharpen. A term given due to the prickly nature of the first species discovered. Another theory refers to the name Egyptians give a thorny species (akakia) that produces a gum.
A prominent location to view Wallangarra Wattles in their natural habitat is just north of the New South Wales-Queensland border. The Girraween National Park (40 minutes south of Stanthorpe) is home to many specimens where they have adapted to poor soil conditions and sub-zero temperatures. The common name of the Wallangarra Wattle refers to the town on the nearby border of New South Wales and Queensland.
