Native to south-eastern USA (i.e. Alabama, Florida, Georgia, southern Louisiana, southern Mississippi, North Carolina, South Carolina and south-eastern Texas), Mexico and the Caribbean (i.e. Antigua and Barbuda, Guadeloupe, Jamaica and St. Lucia).
This species is widespread but scattered in Australia, and is mainly found in coastal districts. It has been recorded in south-eastern and central Queensland, in some parts of eastern New South Wales, in the ACT and in south-western Western Australia. It is also sparingly naturalised on Lord Howe Island.
Also naturalised overseas in other parts of the Caribbean (e.g. Puerto Rico and the Virgin Islands) and in New Caledonia.
Yucca (Yucca aloifolia) is regarded as an environmental weed in New South Wales and as a potential environmental weed or "sleeper weed" in other parts of Australia.
