Native to southern USA (i.e. south-western Kansas, Oklahoma, New Mexico, Texas, Arizona, southern California and southern Nevada) and Mexico.
This species is widely naturalised in Australia, but has a scattered distribution. It is present in many parts of Queensland and well as in northern Western Australia and south-western New South Wales.
Also naturalised overseas in southern Africa, western Asia (i.e. Saudi Arabia), the Indian Sub-continent (i.e. India and Pakistan), south-eastern Asia (i.e. Burma) and tropical Southern America.
Honey mesquite (Prosopis glandulosa var. glandulosa) is regarded as an environmental weed in Queensland and Western Australia, and as a potential environmental weed or "sleeper weed" in many other parts of Australia. In addition to this, the mesquites (Prosopis spp.) are one of the 20 Weeds of National Significance (WoNS) in Australia.
Honey mesquite (Prosopis glandulosa var. glandulosa) is listed in the Global Invasive Species Database (GISD), and is regarded to be among the top 100 of the world’s worst invasive alien species.
