Plant in full sun to filtered shade where once established it is frost tolerant and moderately drought tolerant. Hardy to 15-20 degrees F. As with many in the genus, it is relatively short lived for a tree but for 30 years or so makes a dramatic statement in the garden as a trained-up street or patio tree or left with lower branches as a large shrub or low branched tree. A great plant for slopes.

Matt Ritter in his A Californian's Guide to the Trees Among Us in his listing for Acacia baileyana notes that "This species is popular as a shapely, midsized street tree in cooler coastal cities". It has been identified as invasive in other mediterranean climate regions of the world and documented to have reseeded in areas within California, so is best not used near the urban–rural interface or close to sensitive wildland habitats.

Acacia baileyana has a very restricted natural distribution confined to the vicinity of Cootamundra in southern New South Wales, Australia where it is commonly called the Cootamundra Wattle. The name Acacia comes either from the Greek word 'akazo' meaning "to sharpen" or from the Egyptian word 'akakia', a name given to the Egyptian Thorn, Acacia arabica. The specific epithet honors the Frederick Manson Bailey (1827-1915), Australian botanist and son of colonial botanist John Bailey (1800-1864). The species, Acacia baileyana was first introduced into California in 1903 by Dr. Francesco Franceschi (Emanuele Orazio Fenzi). The purple leafed cultivar Acacia baileyana 'Purpurea' cultivar that we grow came into cultivation in California around 1935, both it and the species received the Royal Horticultural Society's Award of Garden Merit in 1993.  This description of Acacia baileyana is based on our research and our observations of this plant growing in the nursery, in our own garden and in other gardens. We would appreciate getting feedback of any kind from those who have any additional information about this plant, particularly if they disagree with what we have written.
