Although originally native to Australia, the Black Wattle (aka. Early Green Wattle; Acacia decurrens) has naturalized and found now in many other regions, including North & South America, Africa, Europe, New Zealand, and Japan—so widespread that it is referred to as the “Green Cancer” in South Africa. Where it is naturalized, it is often found in disturbed areas, like roadsides.
The trees grow between 7-50 feet tall with a branching trunk, feathery green leaves and clusters of fragrant yellow flowers that look like “puffs” with their numerous stamens.
The tree itself is sometimes used in agroforestry situations as it grows quickly and can be used as a source of firewood, as a shelter tree or windbreak. The roots are also used to help stabilize soil.
The bark is useful as a source of tannins and used for leather tanning widely. The flowers have been used to produce a yellow dye, and they are also edible and sometimes used to make fritters. The seed pods that follow are also used for making a green dye. The wood is used for fuel and low-grade timber.
The Black Wattle flower is also used in foods as a flavoring. A gum can also be obtained from the Black Wattle that is useful as a substitute for gum Arabic, for use in foods. It is also used for soothing sore throats and as a mild expectorant. It is sometimes used in cosmetics, though less than other Acacia gums.
The bark has been used by the Aboriginal people of Australia for treating dysentery, diarrhea and skin ailments due to astringent properties.
Through scientific investigation, The Black Wattle has exhibited antimicrobial, antioxidant, anti-inflammatory, and astringent properties.
