Hymenocallis pimana, named in 1990, was discovered in the Mexican Sierra Madre Occidental mountains in the states of Chihuahua and Sonora. In the wild, Hymenocallis pimana is found in large colonies near waterways at 6,000' elevation. Pima spider-lily is one of the showiest spider lilies we grow. The tight, but fast-offsetting clump is topped with hundreds of white, nocturnally-fragrant flowers in mid-June (NC) held atop 18" tall scapes. Despite its wet origins, we grow it in our desert garden around agaves, where it thrives. The Pima people of Pimana also use the bulbs for food, but only after boiling them in lye to remove the natural toxins...perhaps a reason for the paucity of remaining Pima tribe. We recommend them for ornamental use only.
