Additional comments: Unlike other Yucca species, Chapparal yucca is monocarpic, living for a number of years without flowering and then dying after it does flower. Chapparal yucca is naturally pollinated solely by the California yucca moth (Tegeticula maculata). Chapparal yucca has many ethnobotanical uses. Because of its monocarpic habit, Chapparal yucca is less desirable as a Phoenix landscape ornamental than other Yucca species that flower annually.
