Propagation Methods of Penstemon wherryi Pennell
Penstemon wherryi Pennell, commonly known as Wherry’s beardtongue, is a beautiful flowering plant that belongs to the family Plantaginaceae. The plant is native to North America and usually grows in mountain meadows, rocky slopes, and open woodlands. If you are planning to propagate this plant, there are several methods you can choose from.
Seed Propagation
Seed propagation is the most common method used for propagating Penstemon wherryi Pennell. The plant produces small, black, and shiny seeds that can be collected in the fall after the flowers have faded. To increase germination rates, you can scarify the seeds by rubbing them with sandpaper or soaking them in water for a few hours before planting them.
You can start the seeds indoors in flats or sow them directly in the garden. If planting directly in the garden, make sure to prepare the soil by removing weeds and adding organic matter. Plant the seeds about 1/16 to 1/8 inch deep and keep them moist. Germination usually takes about two to three weeks.
Cuttings
Another common propagation method for Penstemon wherryi Pennell is through stem cuttings. Take cuttings from the plant in early summer, making sure to use a sharp and clean knife or scissors. Cut a stem about four to six inches long and remove the lower leaves, leaving only a few near the top.
Dip the cutting into rooting hormone powder and plant it in well-draining soil. You can place the cutting in a greenhouse or sheltered area until it starts to root. Keep the soil moist and make sure the cutting is not exposed to direct sunlight.
Division
If you have an established Penstemon wherryi Pennell plant, you can propagate it through division. Dig up the plant and gently separate the roots into two or more sections. Make sure each section has some leaves and roots.
Replant the divisions in well-draining soil and keep them moist until they become established. Division is best done in spring or fall when the plant is not actively growing.
By using one or more of these propagation methods, you can easily expand your collection of Penstemon wherryi Pennell plants.
