Similar to A. jucunda which has narrower phyllodes with shorter hairs and a more prominent gland. It is named after the resemblance of the foliage to the South African genus Podalyria. A widely grown and attractive species with bluish-silver foliage and masses of bright yellow flowers in late winter, but it is rather short lived. It should not be grown near natural bushland due to its invasive nature, and has become troublesome in some areas.
