Penstemon ‘Prairie Dusk’ is a hardy hybrid beardtongue with bright green, lance-shaped foliage and upright spikes of rose-purple to violet-purple tubular flowers. It blooms in early summer and may continue periodically into late summer, especially with deadheading. This selection is commonly listed as Penstemon barbatus × strictus ‘Prairie Dusk’, and Plant Delights notes it was developed by Dale Lindgren at the University of Nebraska.

Mature Size: 12–24 in. wide × 18–30 in. tall
USDA Zones: 3a–8b
Form: Upright clump with basal foliage and vertical flower spikes
Light: Full sun
Soil / Water: Average to lean, well-drained soil; low to moderate water once established
Bloom Time / Length: Early summer, with possible repeat bloom into late summer
Wildlife: Attracts hummingbirds, bees, and butterflies

Features & Landscape Uses:
Excellent for sunny perennial borders, pollinator gardens, prairie-style plantings, cottage gardens, rock gardens, xeriscapes, and mass plantings. The rose-purple flowers give strong vertical color and combine well with ornamental grasses, yarrow, salvia, nepeta, coreopsis, coneflowers, sedum, and other sun-loving perennials. Several nursery references describe it as a low-water, long-blooming perennial suitable for borders, rock gardens, and hummingbird plantings.

Care:
Plant in full sun and well-drained soil. Avoid wet, heavy winter conditions, which can shorten the life of penstemons. Deadhead after the first flush of flowers to encourage tidier growth and possible rebloom. Cut old flowering stems back after bloom or in early spring.
