Acacia viscidula, Sticky Wattle


Acacia viscidula, Sticky Wattle, is an erect shrub reaching a height of three metres. Phyllodes are narrow, linear, and leathery with a small hooked point. No glands are visible on the phyllodes.

Flower heads are globular, pale yellow and appear from September to November. One or two flower heads are carried in the axils of the phyllodes on short peduncles. The flowers are numerous but very pale. The pods are straight, sometimes slightly curved.

We know the Sticky Wattle from when we lived on our property, Yallaroo, west of Armidale, on the NSW Northern Tablelands.

Once stock was removed from the property one of the native species to regenerate in large numbers was A. viscidula. It was one of seven wattles that occurred naturally on Yallaroo.

Sticky Wattle would be a useful addition to an informal hedge or screen. Light pruning, after flowering, would prevent plants becoming straggly. A well-grown, dense A. viscidula would provide safe nesting sites for small native birds.

A. viscidula is found on the Northern Tablelands, of NSW and southern Queensland.

The type specimen was named in the mid 1800’s from material collected on the banks of the Lachlan River by Charles Fraser.

Both species and common names means viscid or sticky and refers to the surface of the phyllodes

Propagation is by seed that should be soaked in boiling water before sowing. Cutting propagation should be possible. We never attempted to propagate this species because we already had a plethora of regenerating specimens.
