It is often grown as an ornamental plant, and is native to the southeastern United States, from coastal southeastern Virginia south through Florida and west to Texas.

Yucca × schottii is a plant species in the genus Yucca, native to southern Arizona, southwestern New Mexico, and the northern parts of Sonora and Chihuahua. The common names are Schott's yucca, hoary yucca, and mountain yucca. The "×" in the name indicates that this is a nothospecies, regarded as being a natural hybrid between two other species. In this case, Yucca × schottii is believed to have originated as a hybrid between Y. baccata and Y. madrensis. Yucca × schottii is firmly established and does reproduce freely in the wild.

Yucca declinata is a species of the genus Yucca, family Asparagaceae. It is known only from the vicinity of Bacanora, in the Mexican state of Sonora. Botanist Howard Scott Gentry first collected the species and mentioned it in print, noting the differences between this population and the closely related species Y. grandiflora H. S. Gentry and Y. arizonica McKelvey. He did not, however, describe it as a new species. Later examination of his descriptions and his material led to the recognition of this as a new species.

Yucca baileyi is a plant in the family Agavaceae. It is native to Utah, Arizona, New Mexico and Colorado but has been cultivated elsewhere. Much of its native range is within the boundaries of the Navajo (Diné) Reservation, hence the common name "Navajo yucca." The Navajo people make extensive use of yucca fibers to make a wide assortment of useful and ceremonial items. They also use the roots as soap. It is not considered to be threatened, as it has a large range and an overall stable population.
