Acacia gunnii grows to 1 metre high and wide in dry sclerophyll communities, in various soil types. Widespread in New South Wales (western areas of coastal subdivisions, tablelands and western slopes), as well as South Australia, Victoria, Tasmania, Australian Capital Territory, and Queensland.
The phyllodes (modified leaves) shape is very variable, ranging from semi-trullate (brickies-trowel shape), lanceolate or broadly to narrowly triangular, to 15 mm long and 5 mm wide.
Cream to pale yellow flowers are produced in globular heads, with up to 30 very small, staminate flowers per head. Heads are produced singularly in leaf axils, in June to October.
Seed pods are curved or coiled, to 40 mm long and to 5 mm wide.
Recommended as a rockery plant for its attractive foliage. Requires a well-drained position in full sun to grow at its best and will tolerate some shade.
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.
Most wattles regenerate from seed after fire.
Acacia – from Greek akis, meaing a thorn or “thorny”.
