Penstemon speciosus (Royal Penstemon) is a clump-forming perennial with several ascending to erect stems boasting charming wands of sky blue flowers, 1.5 in. long (4 cm), in late spring to mid-summer. The blossoms attract bees, butterflies, and numerous pollinators. Arising from a branched caudex, the stems are clad with oppositely arranged, narrow, spoon-shaped leaves, up to 6 in. long (15 cm). Royal Penstemon is a good plant for water-wise landscaping, rock gardens, desert gardens, and other ornamental plantings. Royal Penstemon is also chiefly used in wildlife habitat enhancement projects and restoration efforts.
