Acacia parramattensis is known as the Sydney Green Wattle or Parramatta (western Sydney) Wattle and is a spreading tree that may reach a height of 15 metres.
The leaves are bipinnate and dark green. There is a large gland at the base of each pair of pinnae and sometimes a smaller gland between pinnae (see thumbnail). Ball-shaped cream flowers are displayed in summer and winter. Pods are linear and clothed with fine hairs that are pressed close to the surface. Plants may sucker.
The Sydney Green Wattle is a widespread species and occurs on the central coast and tablelands as well as the central west slopes of New South Wales.
Acacia parramattensis has proved to be hardy, free flowering, drought resistant and frost tolerant. The species flowers out of the “normal” spring wattle season.
Acacia parramattensis is a hardy, reliable garden species.
Propagate from seed that should be treated with boiling water before sowing.
The type specimen was collected in Hazelbrook, the Blue Mountains in 1960 and named by Mary Tindale.
The Parramatta Wattle has been confused with A. decurrens. This latter species has high, distinctive ribs on the branchlets.
