Penstemon strictus | Rocky Mountain Beardtongue

$0.00

DESCRIPTION
Penstemon strictus produces upright spikes of tubular violet-blue flowers in late spring to early summer, creating a colorful display that attracts hummingbirds, bees, and other pollinators. Narrow, lance-shaped leaves are deep green and arranged along sturdy stems. The flowers open sequentially along each spike, extending the bloom period while adding vertical texture and movement to the garden.

Native to the Rocky Mountain region of the western United States, this species is adapted to open meadows and foothill landscapes. It is well suited to borders, naturalistic plantings, pollinator gardens, and meadow-style designs, where its colorful flower spikes and architectural form contribute seasonal interest and habitat value.
