Acacia decora

Showy wattle, western silver wattle

Family: Fabaceae subfamily Mimosoideae

Acacia decora is a small to large shrub, often under 2 metres in height but sometimes to 5 metres.

The phyllodes are lance-shaped, to about 5 cm 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 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.

In the garden

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

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