- Gold Dust Wattle is found growing locally on sunny banks often under red box. It can colonise an otherwise inhospitable site and provides a low growing splash of spring lemon yellow colour. This local plant can be trimmed to keep it compact and bushy and promote suckering. Without trimming the Gold Dust Wattle can grow to 2 metres with a straggly look. A good plant for embankments, rockeries and anywhere that receives full sun or dappled light. Good drainage essential. Drought and frost tolerant. Good habitat for small birds and as with other wattles; fixes nitrogen in soil.
