General Description	A fast-growing species reaching up to a meter a year when young. It is considered to be somewhat invasive, and able to readily and rapidly colonise disturbed land, since it is able to fix nitrogen.
Landscape	It is used as a landscape ornamental, but also plays a major role in vegetation re-establishment on mine sites, dunes and disturbed land areas throughout its range and into Africa. In landscape restoration projects, it must be used in very controlled situations since it has the tendency to rapidly colonise areas and overwhelm native vegetation.

Pests	Acacia seed weevil.
