Native Roots - Rocky Mountain Beardtongue (Penstemon)

Native Roots is the product-line label for this Rocky Mountain beardtongue selection of Penstemon strictus. It forms basal foliage and sends up blue to bluish-purple flower spikes; its nursery listing gives a mature size of 36–42 inches tall by 12–18 inches wide. ## Garden placement Use it in a sunny perennial bed, rock garden, or restoration planting with well-drained soil. The selection is listed as moderately drought tolerant. Rocky Mountain penstemon is a semi-evergreen western native; USDA guidance describes the species’ blue flowers and generally shorter 35–70 cm stature, while the [Native Roots seller page](https://plantsofthewild.com/product/native-roots-penstemon-strictus-rocky-mt-penstemon-3-5-pots/) provides selection-specific size and color information. The display label rounds the seller’s height range to 3–3.5 feet. ## Seasonal display Expect the blue flower spikes through summer. Their upright stems rise above the low basal foliage and add vertical color to a naturalistic planting. ## Maintenance Provide good drainage and water during establishment. After flowering, remove spent stems if a tidier finish is desired. Leave healthy basal foliage in place and trim damaged leaves as needed.
