Hesperocallis undulata, commonly known as the desert lily, is a perennial plant native to the arid regions of the southwestern United States and northwestern Mexico. It typically grows in sandy or rocky soils and can reach heights of up to 3 feet. The plant features long, narrow leaves that form a rosette at the base and produces tall flower stalks adorned with white, trumpet-shaped flowers that bloom in spring. This species is well-adapted to its desert environment, thriving in full sun and requiring minimal water. Hesperocallis undulata plays a role in its ecosystem by providing nectar for pollinators such as bees and butterflies. Its unique appearance and resilience make it a notable plant in desert landscapes.
