An open shrub to 3 m high.
It is naturally found mainly on the central tablelands and central western slopes in NSW, from near Coolah in the north, south to Katoomba and Burrinjuck. Possibly occurs in the Bowral to Wingello area in the southern highlands.
It grows in heath and dry sclerophyll forests.
Australian Wattles at least, can be broadly placed into 1 of 3 recognisable groups:
This wattle belongs to Group 1.
Phyllodes (modified leaves) are obovate to elliptic, straight to 3 cm long and about 1.5 cm wide, blue-green to blue-green-grey (glaucous).
Flowers produced in globular heads, to 7 mm diameter with up to 10 very small staminate flowers per head. The heads are produced in racemes in phyllode axils with up to 15 heads per raceme. The flowers are bright yellow with the buds tinged reddish. Flowering is from August to September.
Seed pods straight to slightly curved, to 8 cm long and less than 1 cm wide.
No recorded cultivation notes, however it would be frost tolerant.
It would make an attractive wattle with its glaucous foliage and bright yellow flowers. Usually found naturally on sandy soils so may need a free-draining soil to do well.
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.
Most wattles will regenerate from seed after fire with some species exhibiting suckering from the base.
Acacia is a highly diverse genus, with over 1500 recognised species (placing it in the top-10 most-diverse plant genera) occurring in most continents except for Europe. Australia has about 970 spp., most of which are endemic. There are also about 10 exotic species. NSW has about 235 recognised species. Some species have become weeds in other states outside of their natural range (e.g., wattles from Western Australia into NSW and vice versa).
Acacia – from Greek Akakia – which refers to an Ancient Greek preparation made from one of the many species; the name of which derives from akis, meaning “thorn” – referring to the thorns of species in Africa.
leucolobia – from the Greek lefko (Gk. λευκό) meaning “white” and lobia (λοβια) meaning “beans” referring to the white wax or granules on the seed-pods (a term called pruinose).
This species is not considered to be at risk of extinction in the wild.
