Acacia floribunda

Sally Wattle, Gossamer Wattle

Family: Fabaceae subfamily Mimosoideae

Acacia floribunda is a small tree / large shrub growing to 8 m tall. It is widespread in forests and woodlands in the sub-tropical and warmer temperate regions of eastern Australia from Victoria to Queensland.

It grows mainly in coastal eucalypt woodland communities in the coastal and tablelands subdivisions (i.e. in wet and dry sclerophyll forests) and is most commonly found in alluvial soils along watercourses.

It has naturalised in South Australia, Tasmania and Western Australia.

Phyllodes (modified leaves) are narrowly elliptic to linear, straight or slightly curved, to 15 cm long and 1 cm wide.

This wattle belongs to the group which have phyllodes and very small staminate flowers produced in cylindrical spikes. The spikes can be up to 8 cm long, with 1 or more produced in leaf axils and pale yellow in colour.

Seed pods are straight to strongly curved, raised over and constricted between seeds, to 12 cm long and 0.4 cm wide.

In the garden

Cultivated extensively and suitable for most sunny situations as it is quick growing hence its suitability as a hedge or screen plant. As well, it is useful for controlling erosion, especially in gullies.

Will withstand frosts to -7°C.

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.

Some people are allergic to A. floribunda pollen.

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
