    Beardtongue, which is the common name for Penstemon 'Pensham Louise Wilson', prefers evenly moist soil during its growing season; avoid letting the soil completely dry out. It is best to water this plant deeply once a week, providing about 1 inch of water each time. During hotter, drier periods, you may need to water twice a week, but always check the soil moisture first to avoid overwatering. In cooler weather or if there has been sufficient rainfall, you can reduce the watering frequency accordingly. A good indicator that Beardtongue needs water is when the top 1 inch of soil feels dry to the touch.

  • sunLight

    Beardtongue thrives best in full sun to partial shade conditions. Ideally, the plant should receive at least 6 hours of direct sunlight each day. An east- or south-facing location that offers morning sunlight and some afternoon protection is optimal for encouraging strong growth and vibrant blooms.

  • thermometerTemperature

    Beardtongue is hardy and can tolerate a range of temperatures, but it performs best when the daytime temperatures are between 60 to 75 degrees Fahrenheit. It can survive minimum temperatures down to about 0 degrees Fahrenheit, but growth will be inhibited below this point. Maximum temperatures for healthy growth should not exceed 90 degrees Fahrenheit.

  • scissorsPruning

    Pruning Beardtongue encourages more robust growth and can prevent disease by improving air circulation. After the first bloom, deadheading the spent flowers can promote a second bloom. It is also recommended to prune the plant back in late fall or early spring before new growth begins. This can be done annually, and the best time for a major cutback is when the plant is dormant.

  • circleLife cycle

    Penstemon 'Pensham Louise Wilson' begins its life cycle as a seed, which upon germinating in spring develops a small rosette of leaves at soil level. As the plant matures, it develops a sturdy stem and elongated leaves, with the foliage becoming denser and more robust. In early to mid-summer, it reaches the flowering stage, producing tall spikes adorned with tubular bell-shaped flowers, usually in shades of purple or violet, attracting pollinators such as bees and hummingbirds. After the flowering period, it sets seeds which can be collected or left to self-sow, completing the reproductive cycle. As a perennial, the above-ground portions of the plant die back during fall or early winter, but the root system remains alive, allowing the plant to regrow the following spring. Over time, the plant can become woody at the base, may become less vigorous, and might need to be divided or replaced to maintain its ornamental appeal.

      Spring-Early Summer

    • Penstemon 'Pensham Louise Wilson', commonly known as Beardtongue, is commonly propagated through softwood cuttings. The best time to take these cuttings is in late spring or early summer when the plant is actively growing and the new growth is mature enough but still soft. To propagate, select a healthy, non-flowering stem and make a cutting about 4-6 inches (10-15 cm) long. The lower leaves should be removed, and the cut end may be dipped in rooting hormone to encourage root development. The cutting should then be placed in a well-draining soil mix, ensuring that at least one node (where the leaves were removed) is beneath the soil surface. The cuttings need a warm environment and consistent humidity, which can be maintained by covering the pot with a plastic bag or using a propagation dome. After a few weeks, roots will form, and the new plants can be gradually acclimatized to normal conditions and eventually transplanted.
