Discovered as a chance seedling by the late Bert Wilson of Las Pilitas Nursery, this hybrid of Penstemon heterophyllus is longer blooming, longer lived and noted for its better adaptability to clay soil. Luminous, true sky blue, 1.5” snapdragon-like flowers appear in profusion on 18” stems from Spring thru mid-Summer, fading to rosy-purple as they age. Glossy blue-green linear foliage creates a nice evergreen mat to 2’ across. Unbeatable blue color for the dry, well-drained garden, rock gardens and containers. Dead-head to prolong bloom season. Hummingbirds! Deer resistant! Hardy to 10 degrees F.
