From Wikipedia, the free encyclopedia
Acacia decurrens (Acacia
bark, Early black wattle, Green
wattle, Sydney wattle, Wattle
bark) is a perennial tree or shrub native to the Greater Blue Mountains
Area, which is a World Heritage Site in the Blue Mountains of New South
Wales, Australia. It
is cultivated throughout Australia and the world, and has
naturalised in most Australian states and also in Africa, the Americas, Europe, New Zealand & the Pacific, the Indian Ocean area,
and Japan. It grows to a height
of 2-10m and it flowers from July to September.[2]
Uses
Uses for it include chemical products, environmental management
and wood.[1]
The flowers are edible and are used in fritters. An edible gum oozes out of the tree's
trunk and it can be used as a lesser-quality substitute for Gum
Arabic, for example in the production of fruit jelly. The
tree's bark has astringent properties, but it has to be stored for
a year before it can be made use of. It is used as an anti-diarrheal
medicine. The bark contains about 37-40% tannin. The flowers are used to produce yellow
dye and the seed pods are used to
produce green dye.[3] An
organic chemical compound called Kaempferol is what gives the flowers of
Acacia decurrens their color.[4]
