An erect or spreading shrub normally with multiple stems and reaching a height of 4 metres with a spread to several metres. The bark is smooth, grey or brown.
It occurs mostly on the central tablelands, central western slopes and north-western slopes in NSW, from south-east of Katoomba, to the Gulgong-Merriwa area. Then with some disjunct records west of Coonabarabran (Warrumbungle National Park), with a few scattered records further north-east.
It is found in dry sclerophyll woodlands, often on sandy soils and rocky sites.
Australian Wattles at least, can be broadly placed into 1 of 3 recognisable groups:
This wattle belongs to Group 1.
Phyllodes are linear, up to ten centimetres long, seven millimetres wide, bluish grey and slightly curved with a small gland near the base.
Flowers are held in globular heads with 12-16 individual staminate flowers in each head. The heads are arranged in racemes of up to 14 in leaf axils. Flowers are deep yellow and cover plants in spring.
Pods are straight to slightly curved, up to nine centimetres long and constricted between each seed.
The Tablelands Wattle is one of many “shrubby wattles” that could be used to create colourful hedges.
As the flowers fade cut off each branch behind the spent blooms. This will prevent plants becoming straggly, encourage bounteously blooming and prolong the life of the plants.
Can tolerate dry conditions once established. It is found naturally on rocky loams to sandy soils so may need such conditions to thrive. Very attractive foliage contrast with its blue-grey phyllodes.
Propagate from seed that should be treated with boiling water before sowing and possibly cuttings.
Most wattles will die in a fire and regenerate from seed. Some species exhibit suckering from basal parts and roots.
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 (eg: 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.
caesiella – Latin – derived from caesiellus meaning “blue-grey in colour” – referring to the phyllode colour.
This species is not considered to be at risk of extinction in the wild.
