Acacia fimbriata (MIMOSACEAE) Brisbane Wattle, Fringed Wattle

Plants to Plant

Fast growing, profusely flowering wattle native to South-East Queensland and Northern NSW. Good screen plant, gap filler. Hardy in most situations. Usually a bushy shrub or small tree to 4-6 m high with attractive, weeping light green foliage. New growth is paler, sometimes reddish. In a revegetation site, Brisbane Wattle grows fast and responds well to being trimmed of lower branches, which concentrates growth in the canopy and makes it easier to prevent exotic, suffocating vines from taking hold. Acacia fimbriata is also known as Fringed Wattle because of the microscopic hairs along the phyllodes.
