Rocky Mountain Beardtongue

Penstemon strictus

Honeybees forage on Rocky Mountain beardtongue for nectar and pollen, though bumblebees are the primary visitors due to the tubular flowers. Peak bloom hits in late spring to early summer (May-July), offering mid-season support in its native range. Drought-tolerant and low-maintenance, but ensure well-drained soil to prevent root rot in wet conditions.
