Acacia confusa
Also called Formosan Koa, Acacia Petit Feuille, Formosa Acacia, Formosa Koa, Taiwan Acacia
In Singapore: Formosan Koa, Fine Leaved Wattle, Taiwan Acacia (Grown in Singapore)
Acacia confusa is a fast-growing perennial tree from Taiwan and the Philippines, grown for timber and slope stabilisation and now invasive in many tropical Pacific areas including Hawaii. It needs full sun and warm, frost-free conditions.
Acacia confusa is a perennial tree native to South-East Asia. Some common names for it are ayangile, small Philippine acacia, Formosa acacia (Taiwan acacia), Philippine Wattle, and Formosan koa. It grows to a height of 15 m. Originally native to southern Taiwan's Hengchun peninsula and the northern islands of the Philippines, the tree has become very common in many tropical Pacific areas, including Hawaii, where the species is considered invasive.
The wood has a density of about 0.75 g/cm3. In Taiwan, its wood was used to make support beams for underground mines. Acacia confusa is challenging to work and for this reason was traditionally burned as firewood or turned into charcoal in Taiwan. In later years it was exported to China to be made into wood flooring for the American market. At its height Taiwan exported more than 1,000 containers of Taiwan acacia to China. More recently it has been used domestically to produce high value wood products like musical instruments, furniture, and bathtubs.
