Hesperaloe parviflora Coral Glow PP#29,626 (Texas Yucca) blooms all summer with six-foot tall spikes of glowing coral-orange flowers. A cross between a yellow and red flowered plant, ‘Coral Glow’ has been an outstanding performer in founder and chief horticulturist David Salman’s Santa Fe garden. It's ever-blooming because the plant is essentially sterile, putting all its energy into growing flowers instead of seeds. Hesperaloe will often take 2 to 3 years to reach blooming size. So be patient and protect it from deer who love to eat the succulent leaves. A High Country Gardens Introduction.
