Leaves of hesperocallis undulata
grow only around the base of the thick, rigid stem, which can reach a height of 6 feet and bears many large, funnel-shaped flowers; each has 6 petals which are mostly pure white but have a greenish-yellow band underneath. At the center is a cluster of yellow anthers and white stamens. The plant inhabits the hottest, driest regions of the Southwest, flowering after the infrequent rainfall. The bulbs are edible, and have a taste similar to garlic. Hesperocallis is a monotypic genus, and the sole species has similarities both to the lily and agave families.
