Agave victoriae-reginae, the Queen Victoria agave or royal agave, is a small species of succulent flowering perennial plant, noted for its streaks of white on sculptured geometrical leaves, and popular as an ornamental.
Agave victoriae-reginae is a very slow growing but tough and beautiful Agave. It is consider the to be one of the most beautiful and desirable species. It is extremely variable with the very open black-edged form sporting a distinct name (King Ferdinand's agave, Agave ferdinandi-regis) and several forms that are the more common white-edged form. Several cultivars have been named with different patterns of white leaf markings or no white markings or white or yellow variegation. It is endemic to the arid lower elevations of the Sierra Madre Oriental Mountains in the state of Coahuila and south of Nuevo Leon in north-eastern Mexico.
