Hairy Beardtongue
Penstemon hirsutus
The soft, downy stems that give this compact native its name are just the beginning — lavender-throated flowers from May to July make it one of the most valuable bumble bee plants in the eastern garden.
Hairy Beardtongue takes its common and scientific names from the distinctive downy texture of its stems, a feature that readily separates it from the many other beardtongues of the genus. Native to the dry woods and rocky fields of eastern Canada and the northeastern United States, it produces upright clusters of lavender to violet, trumpet-shaped flowers with whitish lips from May through July, blooming from several stems rising from a shared rhizome.
This species has a particular affinity for thin, well-drained, and often dry soils, conditions that suit the rock garden or a dry bank planting especially well. It tolerates both full sun and partial shade. Cut spent flower stems back after bloom to keep the planting tidy, and expect modest self-seeding that fills gaps without overrunning neighbors. Bumble bees show a strong preference for the flowers, making it a worthwhile addition to any pollinator planting.
