This native plant can form a striking clump of bright-yellow flower plumes in extremely arid sites and in the nastiest soils. It is found in most of Wyoming and prefers barren hills and flats with selenium-rich soils. Because desert prince’s plume concentrates selenium in its tissues, it can be toxic to livestock. In some locations, plants may be short-lived, but moderate reseeding does occur. Though available only from select nurseries, prince’s plume is easy to propagate from purchased seed.
