Acacia mangium
Acacia mangium is a single-stemmed evergreen tree or shrub that grows to 25-35 meter in height. Young trees have smooth, greenish bark; fissures begin to develop at 2-3 years. Bole in older trees branchless for up to 15 meter, fluted, up to 90 cm in diameter; Branchlets acutely triangular. This product is best for growing trees and shrubs which enhance the beauty of garden, landscapes, commercial crops, etc.
Long, hebe-like sprays of fragrant creamy yellow flowers open on branches clad in large leathery leaves. Native to north eastern Queensland in Australia, the Western Province of Papua New Guinea and also the eastern Maluku Islands where it is used mainly for environmental management and timber, when a mean annual height increase of 3 to 4 meters will be obtained if grown near the equator. Its success is down to its extremely vigorous growth rate and its tolerance of highly acidic, low nutrient soils, and also its relative freedom from disease.
