The Chaparral yucca (Hesperoyucca whipplei) belongs to Agavaceae (the Agave family). It is a small evergreen tree that is distributed from south-central to southern California in the United States, as well as Baja California in Mexico. It grows in chaparral (a biome consisting of evergreen shrubs that are adapted to hot, dry summers and cold, wet winters), coastal shrub belts, and oak forests, and its leaves are about 90 cm tall. The leaves are grayish-green and linear, with fine serrations along the edges. After five years or more, it will grow a scape 1 to 3 m tall, and will produce a spike with many white to purple flowers. The fruit is a winged capsule that splits open when it matures, releasing the seeds. DNA analysis has confirmed that this species is genetically distinct from the Yucca genus, and has been placed in the Hesperoyucca genus.
