Growing Guide: How to Grow Penstemon

If you are in search of a perennial that has high-impact, is long-blooming and easy to grow, then Penstemon is perfect for you. With blooms starting in early summer. you will have a showy display of colorful flowers.

How to Grow

Light: Full sun to partial shade.

Soil: Well-draining soil.

Water: The amount of water needed will depend on the water-holding capacity of your soil.

  • Find a sunny spot with sandy or gravel-like soil - avoid enriched soils, too much compost can shorten their life span.
  • Dig holes and plant the root just above the surrounding soil to avoid covering the crown of the plant.
  • Give the plants a good initial watering to settle.

How to Care

  • Water sparingly- Penstemon are not as drought-tolerant as succulents and cacti but they do not need to be watered often. Only water once the top inch of soil is completely dry when established.
  • Deadhead blooms occasionally.
  • Watch out for pests- snails, slugs and spider mites. Penstemons are fairly resilient but pests may appear.
