How to Sow and Plant Penstemon

Sowing Penstemon Directly in the Garden:

  • Direct sow in spring to early summer in full sun in a fertile, well-drained soil. Excellent drainage is essential for penstemon.
  • Remove weeds and work organic matter into the top 6-8 inches of soil; then level and smooth.
  • Sow seeds evenly and thinly and barely cover with soil.
  • Firm the soil lightly and keep it evenly moist.
  • Seedlings will emerge in 10-21 days.
  • Thin to stand 12 inches apart when seedlings are 1-2 inches tall.

Planting Penstemon in the Garden:

  • Select a location in full sun with a fertile, well-drained soil. Excellent drainage is essential for penstemon.
  • Prepare the bed by turning the soil under to a depth of 6-12, inches removing any debris, and lightly raking as level as possible.
  • The addition of organic matter (leaf mold, compost, well-rotted manure) benefits all gardens and is essential in recently constructed neighborhoods.
  • Plant on a cloudy day or in late afternoon to reduce transplant shock.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Unpot the plant and gently loosen the root ball with your hands to encourage good root growth.
  • Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.
  • Use the plant tag as a location marker.
  • Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.

How to Grow Penstemon

  • Keep weeds under control during the penstemon growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination.
  • Penstemon Perennial FlowersMulches can also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time.  Always keep mulches off a plant’s stems to prevent possible rot.
  • Careful watering is essential in getting penstemon perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry. One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.
  • Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary.  Good air movement is also important for penstemon plants.
  • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer, as higher rates may encourage root rots.
  • Cut back flower stalks to the ground after flowering to promote reblooming.
  • Remove and discard foliage after a hard frost in fall.
  • In colder regions, apply another layer of mulch (1-2 inches) after the ground freezes in fall. Evergreen boughs (from Christmas trees) provide additional protection. Remove this mulch in the spring.
  • Divide plants in spring every three years.

Penstemon Growing Tips

  • Many gardeners do not cut back perennial flower seed heads in the fall, but wait until early spring before the new foliage appears. This provides food for wildlife over the winter.
  • Tall flower spikes can last a week in a fresh arrangement.
  • When left to go to seed, stems with ripe, dry seeds pods are useful in dried arrangements.

Rated 1 out of 5 by from Didn't sprout I was really excited about this flower but it didn't sprout.

Rated 1 out of 5 by from No germination I'm sorry to say that I did not have one seed germinate. I've had great success with my other burpee seeds.

Rated 1 out of 5 by from Never Germinated The seeds never germinated despite being in good amended soil, being in the right zone, and following the germination directions. Very disappointed.

Rated 1 out of 5 by from None have Sprouted I bought this product several weeks ago and planted right away. Not one of the seeds have sprouted and I am very disappointed. I had wanted these for the hummingbirds that live in my area and now I will have to go a different plant that will do the same thing.

Rated 4 out of 5 by from Curb Appeal has slightly higher cost I bought 50 of these about a month ago, put them into the ground immediately when they arrived, setting them in Miracle Grow flower planting soil. The bed already had a good soil/peat moss/leafpro mix. They took off slowly, despite frequent watering and Miracle grow fertilizer. The ones set in a raised bed lagged behind significantly. The plants are now full height, filled out into a bed when spaced per Burpee recommendations. The color of red-pink and delicate grape size blooms are impressive because of the density of the number of plants. If spaced too far apart to save money would not give much of an impression due to height and size of bloom. The one key selection factor was drought resistance. Sorry, these are not and the blooms and stems quickly brown up after 3-4 days if not watered. A week ago I mulched them with 5-6" of a good dark mulch and this has helped a lot but I still need to water every other day. I am going to hold off final review until end of the summer and see if a deeper root network gives me more time between waterings.

Rated 5 out of 5 by from Very pretty flower. I planted this flower the day I received it and it has grown into a very pretty red flower. Kind of delicate but the hummingbirds are quite taken with it.
