Acacia juncifolia

Rushed-leaved Wattle

Family: Fabaceae subfamily Mimosoideae

Acacia juncifolia is an erect to spreading shrub to 3 m high, in dry sclerophyll forests and woodlands, in sandy soils. It grows in north-eastern NSW, on the central and north-western slopes as well as the central and north coast subdivisions, extending into QLD. Curiously, it is not known to grow on the northern tablelands. It grows north from the Glenbrook area in the lower Blue Mountains.

The phyllodes (modified leaves) are rigid, very narrow and linear, to 20 cm long and about 1 mm wide with an acute apex. They are 4-angled in cross-section.

Flowers are produced in globular heads, up to 6 mm diameter which are solitary in the phyllode axils; yellow to deep yellow. Each head can have up to 30 very small staminate flowers.

The seed pods are 10 cm long and 3 mm wide, straight to slightly curved.

In the garden

Not a lot is known about its cultivation but reported to be cultivated (see resources). It is an interesting architectural plant with its long narrow upright phyllodes. Reported to need a well-drained soil.

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.
