Acacia amblygona

Acacia amblygona

Family: Fabaceae subfamily Mimosoideae

Acacia amblygona is a small shrub reaching a maximum height of 1.5 metres.

In Western Australia it is native to an area along the south coast near Ravensthorpe in the Goldfields-Esperance region of Western Australia where it grows in stony soil.

It is found in coastal and inland parts of New South Wales north from Lake Cargelligo and extends into southern parts of Queensland. The species is common in the Pilliga Scrub, central NSW. 

All forms have dark green, rigid, almost triangular, prickly phyllodes. 

Flower heads are golden and globular. Flowers cover the plants between July and October. The seed pods are coiled or curved and constricted between the seeds. All forms are very showy particularly the prostrate form.

In the garden

A hardy wattle good for rockeries and to control erosion. 

Prefers well drained soils in a sunny position and is spectacular in flower.

Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these occurring.

Propagation

Propagation is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.

Other information

The prostrate form of A. amblygona (sometimes sold under the name ‘Winter Gold’) has been in cultivation for many years. It is a reasonably hardy ground cover which can spread to about 1-1.5 metres in diameter. and is very spectacular when in flower. The upright forms are rarely seen in cultivation.

Most wattles regenerate from seed after fire.

Acacia from Greek acis, meaning a thorn.
amblygona from Greek amblys (αμβλύς) gonia (angle) – meaning blunt-angled, possibly referring to the shape of the phyllodes.

Not considered to be at risk in the wild.
