Agave virginica, synonym Manfreda virginica, commonly known as the false aloe, American aloe, Virginia agave, and eastern agave, is a species of agave. Older references occasionally used rattlesnake master to refer to Manfreda virginica, though current usage of rattlesnake master primarily refers to Eryngium yuccifolium. It is native to the central and southeastern United States and northeastern Mexico, where it is found in prairies, upland rocky glades, and sandy open woods.
