Wasatch Beardtongue (Penstemon)

Wasatch beardtongue (Penstemon cyananthus) is a blue-flowered native perennial of Utah’s Wasatch region and nearby western mountains. Its slender stems carry dense clusters of tubular flowers above bright green leaves, and the plant is suited to sunny, sharply drained sites. ## Garden Use The species occurs across habitats from sagebrush grassland to alpine settings. In gardens it can bring a naturalistic vertical accent to a rock garden or native planting; size and bloom timing vary with elevation and local conditions. [The Utah Native Plant Society profile](https://www.unps.org/plant%20data%20base/plant%20sheets/penstcyanan.html) describes its regional habitat and blue flowers, while the [RHS plant profile](https://www.rhs.org.uk/plants/218827/penstemon-cyananthus/details) confirms the botanical name and Wasatch beardtongue common name. ## Growing Conditions Give it full sun and well-drained soil. It is cold hardy and drought hardy in its native region; on the Wasatch Front, established plants need little or no supplemental irrigation. Avoid heavy, persistently wet soils. Hardiness varies with provenance, so choose plants suited to the local elevation. ## Maintenance Water new plants until established, then reduce irrigation according to rainfall and site conditions. Allow some seed to mature if naturalizing is desired, or remove flower stems before seed dispersal.
