List of Yucca species
This is a list of the species in the genus Yucca. They are commonly called yuccas in English, but are also called Adam's needle or Spanish-bayonet.
Plants of the World Online and World Flora Online both list 50 valid species. In addition, POWO lists three other species, Yucca jaegeriana, Yucca muscipula, and Yucca pinicola, that WFO lists as unchecked or as a synonym of another species. There are also two natural hybrids, Yucca × schottii, which was formerly listed as a species under various names, and Yucca × quinnarjenii.
