A spreading shrub or tree to 5 metres in height. The ferny, bipinnate leaves are usually grey-green or slightly bluish in colour. These leaves are retained throughout the life of the plant and are not replaced by phyllodes. The large, globular, golden-yellow flower heads are produced in dense clusters and produce a spectacular display. These are followed by broad, flat pods. A pale waxy bloom often covers the stems and young pods of the plant.
