This short-trunked desert perennial is often mistaken for yucca. A 9-15 ft. flower stalk, bearing a 2-3 ft. spike of yellowish flowers, is subtended by a basal cluster of dark, bluish-green leaves with evenly-spaced spines and a wide, cupped base. The leaf cluster is 1 1/2-2 1/2 ft. tall.
Trunks split open during dry spells, allowing wildlife access to the spongy interior and leaf bases
