It is an erect, slender, sparsely branched shrub or tree, which grows to 1.5 to 7m high

Skeletal soils over sandstone, basalt or quartzite. Ridges, stony hills, amongst rocks

Geographic distribution

A very interesting species, it is native from northern Western Australia, and is also found in the Kimberleys in the Northern Territory. It has been also introduced to West Africa


Beard’s Provinces: Northern Province. IBRA Regions: Central Kimberley, Northern Kimberley, Ord Victoria Plain, Victoria Bonaparte. IBRA Subregions: Berkeley, Mitchell, Ord, Ord-Victoria Plains P1, Pentecost, Victoria Bonaparte P1. IMCRA Regions: Cambridge-Bonaparte, Kimberley. Local Government Areas (LGAs): Derby-West Kimberley, Halls Creek, Wyndham-East Kimberley.

Identification

Large, falcate, glaucous phyllodes to 30 cm long by 20 cm wide, which grow on the trunk and persist for many years.

Golden ball flowers, 2 cm diameter most of the year.

Tolerant of extended dry periods but frost tender. Suitable for arid situations. It has the largest leaves of all the acacias, which grow on the trunk and persist for many years.


Alkaloid content

Other uses

A unique plant to grow for it distinctive phyllodes.

Recommended for its foliage. May be used as a feature plant.
