Classification of the genus Acacia (in the wider sense) has been subject to considerable debate. It is generally agreed that there are valid reasons for breaking it up into several distinct genera, but disagreement in the way this should be done. Some authorities have wanted to transfer this species to the genus Racosperma, but the latest decision (in 2011 and still not fully accepted) is that it remains in Acacia[

Acacia verticillata is a thorny, evergreen shrub or a tree with a spreading crown; it can grow up to 10 metres tall[
]. Although it produces leaves as a seedling, llike most members of the genus the mature plant does not have true leaves but has leaf-like flattened stems called phyllodes[
The plant is sometimes harvested from the wild for local use as a food and dye. Grown as an ornamental it can be used as a hedge.

Acacia verticillata is a plant of the warm temerate zone of southeast Australia. It can be grown out of doors in areas with mild winers, being somewhat frost-tolerant and able to tolerate occasional temperatures down to between -5 and -10°c[
Prefers a sandy loam and a very sunny position[
]. Another report says that it needs some shade[
]. Succeeds in dry soils and is found wild on saline soils[
]. Succeeds in any good garden soil that is not excessively limey[
]. Most members of this genus become chlorotic on limey soils[
A fast-growing tree, frequently flowering in a few years from seed[
This species is notably resistant to honey fungus[
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
Flowers - cooked[
]. Rich in pollen, they are often used in fritters.
Plants are heavily armed with thorns and make a good screen or hedge in warm temperate areas[
A yellow dye is obtained from the flowers[
A green dye is obtained from the seed pods[
Seed - best sown as soon as it is ripe in a sunny position in a warm greenhouse[
]. Stored seed should be scarified, pre-soaked for 12 hours in warm water and then sown in a warm greenhouse in early spring. The seed germinates in 3 - 4 weeks at 25°c[
]. As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in a sunny position in the greenhouse for their first winter. Plant them out in late spring or early summer, after the last expected frosts, and consider giving them some protection from the cold for their first winter outdoors.
Cuttings of half-ripe wood with a heel, mid summer in individual pots in a frame[
]. Overwinter in a greenhouse for the first winter and plant out in their permanent positions in late spring or early summer. Fair percentage[
