Penstemon: Direct Sow or Potted Plant Perennial

How to Sow and Plant

Sowing 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 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

  • Keep weeds under control during the 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.
  • Mulches 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 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.
  • 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 such as Garden-tone, 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.

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.

Penstemon, Carillo Red is rated 2.3333 out of 5 by 3.
Rated 5 out of 5 by from Absolutly Beautiful! I bought this last year and upon arrival it didn't look like much (only a few leaves and stems). I put it in the ground in the front of my house that gets a ton of afternoon sun and it took a few months for it to take a good hold but once it did, oh my! It is at least 4 times as big as it was last year and did wonderful through the winter. The hummingbirds loved the flowers last summer and it was so nice to have flowers in the summer-fall. Awesome plant!!

Rated 1 out of 5 by from Here today Gone the next Had just the place for this beautiful plant; arrived before my areas last frost date. Sure enough the freeze came and the plant is gone. Of course it is now out of stock; really defeats ordering in January to avoid this issue.

Rated 1 out of 5 by from Sad Plant Wow...I just don't know about ordering live plants from Burpee. I've ordered a few, and haven't had much luck. This plant arrived Friday as scheduled. I immediately took it out of the box, the plant and container appeared to at one time to have been wrapped in paper. The paper was a bit loose, and there was some soil loose in the box, not much, just a sprinkling. I took the paper off of the "potted" plant, and the plant fell out with the soil, the container was still in the paper. The soil was completely dry, the plant came out of the soil, nothing clinging to the roots, and the plant was on the verge of being crispy. I took it in the house, repotted it in the same pot, same soil, and gave it a huge drink. I hoped for the best, put it on my kitchen (west facing) window ledge, and checked it for the past 2 days, the plant IS now crispy, gray green, it appears to be dead, much like a weed that was pulled and left out in the sun. I'll give it a few more days to see if it recovers, but the quality of this plant leaves much to be desired. I will update soon hopefully with better news. But for now, I wish I had just checked out my local nursery for this plant or another like it, at least for the price I would have gotten a gallon plant and a green hydrated plant.
