Hesperoyucca whipplei is a species of a flowering plant closely related to a yacca and formerly was included in the genus Yucca. It is native to central California east to extreme south-west Arizona and south into Baja California where it occurs mainly in chaparral, coastal sage scrub, and oak woodland plant communities at altitudes of 0–2500 m.
Hesperoyucca whipplei is a dense rosette-forming plant with rigid, stemless, silver-grey leaves that are margined yellow or brown and have a very sharp tip. The leaves are >90 cm (rarely >125 cm) long and are >2 cm wide with edges that are finely saw-toothed.
Hesperoyucca whipplei usually after 5+ years reaches maturity and then during mid-spring to summer it flowers and then it usually dies. Flowering occurs as a single a stout stalk which grows extremely fast and will reach a height of 0.9–3 m.
The flowering spike bears hundreds of 3 cm diameter, drooping, fragrant, bell-shaped creamy-white flowers that are sometimes tinged with purple. The densely branched panicle is >70 cm broad and covers the upper half of the spike.
The fruit is a dry winged capsule, which splits open at maturity to release the seeds.
