An unusual, bright white form of our native foothill penstemon that dazzles with dense blooms from spring to fall. Spring sees the emergence of soft yellow buds on this evergreen perennial, which then open as snowy fresh, tubular flowers. The showy flower stalks reach 18 inches to 2 feet and look spectacular cascading out of a container. A natural selection, its name is an abbreviation of Glendora Mountain Road, the area just north of Los Angeles where it was found. As beloved by hummingbirds and pollinators as the more common blue-violet form of this species and even more shockingly floriferous. Plant in full sun to very light shade where it will have good drainage, and provide occasional to no water. Thrives in large pots. Drought tolerant.
