Hesperocallis is a genus of flowering plants belonging to the family Asparagaceae. It is native to the deserts of the southwestern United States and Mexico. The most well-known species is Hesperocallis undulata, commonly known as the desert lily. This plant typically features long, narrow leaves and produces tall flower stalks adorned with white, trumpet-shaped flowers. Desert lilies thrive in arid environments and are adapted to survive with minimal water. They bloom in spring, attracting pollinators such as bees and butterflies. The plant's ability to withstand harsh conditions makes it an important part of its ecosystem, contributing to the biodiversity of desert habitats.
