Description

Penstemon x mexicali ‘Psmyers’ Shadow Mountain® (Beardtongue) is a unique variety with striking flowers. Abundant flower spikes rise above a mound of attractive glossy green narrow leaves, with blooms lasting for months from summer to fall. This cousin of Plant Select’s RED ROCKS® and PIKES PEAK PURPLE® Penstemons, was discovered at Welby Gardens in Denver, CO.

This Penstemon is tolerant of many different soil types and can be grown in full sun as well as light shade. While SHADOW MOUNTAIN® does very well grown in a xeric situation, it blooms heavier and more continuously with moderate watering. However, avoid frequent, heavy watering as this will make it floppy. Deadheading will prolong bloom. Cut back each fall for a fresh new look in spring. Seedlings may not be true to variety color.

Planting & Care

Tips for growing Penstemon (Beardtongue)

Penstemon are generally evergreen and have beautiful flowers that are very attractive to hummingbirds. Most varieties are rabbit resistant.

  1. They need “elbow room,” maximum sun, heat and don’t like to be crowded by other plants.
  2. Plant only in well-drained soils; clay soils and Penstemon are incompatible.
  3. Avoid overly enriched soils; too much compost and fertilizer will shorten their lifespan.
  4. They establish quickly and the amount and frequency of watering needs to be reduced after about 8 to 10 weeks to create dry conditions.
  5. When using drip irrigation, be sure to put the emitter off to the side of the plant, not right on top of the root ball to avoid overwatering the plant.
  6. Plant high, leaving the top of the rootball just above the surrounding soil to avoid burying the crown of the plant.
  7. Mulch with gravel or pine needles in arid climates. No mulch is needed where conditions are moister. Always avoid bark, grass clippings, or compost as mulch materials.
  8. Allow some of the plants to set seed (don't deadhead all of the flower spikes)*.
  9. Fertilize sparingly. One time each year in the fall is enough. Apply a light application of an organic or natural fertilizer such as Yum Yum Mix as a top dressing around the plants. Don't use high nitrogen water soluble fertilizer like Miracle Grow.

*To keep penstemon that have finely textured or matted evergreen foliage looking their best, you'll want to 'deadhead" them. Shear off the fading flowering spikes just as the plant is going out of flower. Gently bunch the flower spikes together with one hand and cut them off at the point where they go down into the mat of foliage with your clipper in your other hand. Recommended for the following varieties: P. pinifolius types (‘Compactum', ‘Mersea Yellow', ‘Nearly Red', ‘Magdalena Sunshine' and ‘Tall Orange Mix'), as well as Penstemon linarioides v. coloradensis and Penstemon virens ('Blue Lips').
