It seems to tolerate our clay soils and has withstood moderate frosts and the long drought very well. It performs well in full sun and part shade, has a lovely sweet perfume and is mobbed by the bees when in flower.
Genus: From the Greek akakia, the name of Acacia arabica, of tropical and Western Asia (from akis, a sharp point, as this is a spiny species).
