Penstemon (Penstemon Strictus Rocky Mountain) - They are absolutely stunning in the xeriscape wildflower garden or in a naturalized setting! Grown from flower seeds, Rocky Mountain Penstemon is a fine source of a brilliant blue color, and it is a native United States plant that gardeners in many parts of the country have come to treasure for its beauty and water conservation. The plant has intensely colored blooms that are 1 inch across and shaped somewhat like a snapdragon. They open along sturdy, erect 24 - 36 inch stems giving you enough bloom spikes for cutting and bringing into the house for bouquets. Gardeners are not the only ones who enjoy Penstemon! Hummingbirds and butterflies will be visiting in droves to feed on the nectar.
Rocky Mountain Penstemon seed is considered a wild flower seed. It is recommended to directly sow these seeds outdoors into prepared beds in late fall. In the late fall, loosen the soil and scatter the seed thinly on top allowing spacing so that you can move the plants after they have developed if you need to. Put a very thin layer of coarse sand or potting soil over the flower seeds. They will lie dormant throughout the cold weather of winter, but the moisture and coldness is actually helping to soften the seed coat, and once spring temperatures come, they will begin to sprout. They will become drought tolerant, sturdy plants by mid-spring, and if you need to, the seedlings are easy to transplant to permanent locations at that time. Rocky Mountain Penstemon care includes deadheading the spent flowers to promote continued blooming.
Common Questions
Do I need to deadhead my penstemon flowers?
Yes, deadhead your spent blooms to encourage a longer bloom season.
Do I need to prune back my plants for winter?
Yes, cut back your plants in late fall or early spring to encourage new healthy growth.
Should I fertilize my plants?
Generally, penstemon does not need fertilized. However, giving it a light application in the fall can help boost growth and flowering.
Will deer eat my penstemon plants?
No, deer typically stay away from these plants.
Why did my plant not survive the winter?
Penstemon requires good drainage, as the crown is prone to rotting in poorly drained soils, particularly during winter. Additionally, we suggest providing extra winter protection in colder regions.
Does penstemon attract pollinators?
Yes, hummingbirds, and butterflies love these flowers.
Is penstemon drought tolerant?
Yes, once established the plants are drought tolerant.
How can I use penstemon in my garden?
Penstemon is great for cutting gardens, meadows, borders and pollinator gardens.

Penstemon (Penstemon Hartwegii Sensation Mix) - This 30 inch tall drought tolerant plant produces a wealth of brilliant scarlet, red, and pink tubular flowers with white throats. From June to September, this perennial also called Beardtongue, will reward you with non-stop blooming. Easily established from Penstemon seeds, it is a great addition to any xeriscape flower garden with its deep bronze-green foliage and various color blooms. Penstemon Beard Tongue is native to Mexico and does well in warm climates. It will grow as a perennial in frost free or mild winters and as an annual in other zones.
These flowers attract hummingbirds and butterflies into the garden. Beardtongue will tolerate and even thrive in poor soils, but it requires relatively good drainage. Full sun in cool climates and partial shade in the hottest areas is preferred. Penstemon Hartwegii care includes little water once established as it is resistant to drought.
Sow Penstemon seeds indoors in starter trays or small pots in late winter. Press the flower seeds into the soil but seed should be visible on the surface of the soil. After danger of frost has passed, harden off the seedlings and transplant them into the flower garden. To encourage bushier growth, pinch back the plant at time of transplanting.
