Acacia decora is a small to large shrub, often under 2 metres in height but sometimes to 5 metres tall.
This species is widespread west of the Dividing Range in Queensland, New South Wales and Victoria from Cooktown in the north to the Warby Range in Victoria. It is found on sandy and stony soils usually in eucalypt woodlands. It is also a wattle that regenerates along rural roadsides.
The phyllodes are lanceolate, to about 50 mm long and only about 7 mm wide; blue-green in colour.
Like many wattles, globular flower-heads are produced which can have about 30 tiny flowers in each head. These heads are about 4.5 to 6 mm across. The heads are then clustered in terminal (end of braches) and axillary (leaf axes) groups (racemes). It flowers from April to October.
Seed pods are straight to shallowly curved about 5–10 cm long.
This is a hardy, showy species which is tolerant of a wide range of conditions. It prefers well-drained soils in light shade to full sun.
A. decora is a worthwhile addition to gardens in many areas of Australia as it is one of the showiest wattles.
Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these pests 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 will die in a fire and regenerate from seed. Some species exhibit suckering from basal parts and roots.
Acacia is a highly diverse genus, with over 1500 recognised species (placing it in the top-10 most-diverse plant genera) occurring in most continents except for Europe. Australia has about 970 spp., most of which are endemic. There are also about 10 exotic species. NSW has about 235 recognised species. Some species have become weeds in other states outside of their natural range (eg: wattles from Western Australia into NSW and vice versa).
Acacia – from Greek Akakia – which refers to an Ancient Greek preparation made from one of the many species; the name of which derives from akis, meaning “thorn” – referring to the thorns of species in Africa.
decora – from Latin decorus meaning “graceful in appearance”.
This species is not considered to be at risk of extinction the wild.
