Acacia obliquinervia

Mountain Hickory Wattle

Family: Fabaceae subfamily Mimosoideae

A medium-sized tree, growing to 15 m high, in south eastern NSW, ACT and Victoria in dry to moist sclerophyll forest, often on sandstone. In NSW, it grows from the Goulburn River Valley on the central western slopes, south through the tablelands.

Phyllodes (modified leaves) are obovate to narrowly oblanceolate, to about 15 cm long and to about 5 cm wide and grey-green in colour

Flowers are arranged in globular heads, to 8 mm diameter, with up to 30 very small staminate flowers per head, yellow in colour, occurring August to December. The heads are arranged in racemes or panicles, in phyllode axils, with up to 16 heads per raceme.

Seed pods are straight or slightly curved, to 15 cm long and to 2.5 cm wide.

In the garden

A suitable plant for ornamental foliage.

Hardy in well-drained soils. Needs reasonable moisture to thrive.

Bright yellow flowers standout well against the grey foliage.

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

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

Most wattles regenerate from seed after fire with some species exhibiting suckering from bases or trunks.

Acacia from Greek acis, meaning a thorn or “thorny”.
obliquinervia – refers to the oblique venation of the phyllodes

Not considered to be at risk in the wild.
