Acacia gordonii is a shrub potentially reaching 1,5 m tall, growing in dry sclerophyll forest and heath on sandstone outcrops in New South Wales between Bilpin in the north to Faulconbridge in the south in the foothills of the Blue Mountains. It is a rare and endangered plant in the wild.
Phyllodes (modified leaves) alternate or sometimes irregularly whorled or clustered, to 1.5 cm long and only 0.1 cm wide.
Flowers are produced in globular heads, to 8 mm in diameter. Each head can have up to 35 very small, staminate flowers. Heads are produced solitarily in leaf axils, between August and September.
Pods are straight or flat, to about 6 cm long and 1.5 cm wide
This species is not commonly cultivated but is available. Sutherland members have sourced them from regional meetings – see Youtube video link: (https://www.youtube.com/watch?v=DJ2sPlGcT4w). Grows well in pots.
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 is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.
This species may be confused with A. baueri subsp. aspera which mas sessile (no peduncle) flower heads).
Most wattles will regenerate from seed after fire.
Acacia – from Greek akis, meaning a thorn or “thorny”.
gordonii – named in Honour of Eric Gifford Gordon about who not much is known but who apparently found the plant near Bilpin in 1961.
A. gordonii is listed as threatened and classified endangered under the NSW and Commonwealth legislation.
