Hairy acacia in not grown in the U.S. It can be planted against hot walls and tolerates rocky soil. Though drought tolerant, it benefits from occasional irrigation during hot, dry weather. Due to the spiny stems, plants should be sited away from traffic areas. This species is hardy to about 20° F (-6.5° C). Litter is minimal.
