(formerly listed as O. coryi) This easy to grow Yucca Do introduction was found in Coahuilia Mexico at 6500'. The clumping basal rosette has narrow flat leaves. From the rosette emerge flowering stems that lie on top of the ground, each terminating in upward facing large 2"+ flowers of bright yellow. As the day progresses, the flowers change to a gorgeous peach color...great for the rock garden. Unlike many other members of the clan, this evening primrose does not spread by runners!
