Hesperocallis undulata A. Gray
Desert Lily, Ajo Lily
The Hesperocallis lily family is native to the North American southwest. (Hesperocallis comes from the Greek words hesperos (Ἓσπερος) and kalos (καλὸς), meaning “western beauty.”) Traditionally classified as lilies, these plants are actually more closely related to agaves.
Identification: Plants are 12-71" (30-180 cm) in height. Leaves are long 8-20" (20-50 cm) and narrow ¼-½" (8-15 mm), with undulating serrated edges. White, showy, trumpet-shaped flowers occur in groups of 4 to 18, each 4-12" (10-30 cm) long and about 3" (7.6 cm) in diameter. Each flower has six petals and yellow anthers.
Edibility: Desert lily bulbs, which can be quite large, have a garlic-like flavor, and may be baked or boiled, or eaten raw.
