  • water dropWater

    Beardtongue requires watering that allows the soil to dry out slightly between waterings; overwatering can lead to root rot. In general, give the plant about 1 inch of water once a week during the growing season, but adjust based on rainfall and temperature. Water the plant at its base to avoid wetting the foliage, which can lead to fungal diseases. During the winter, reduce watering to whenever the soil is completely dry to a depth of an inch. It's best to water in the morning to allow any moisture on the leaves to dry out over the course of the day.

  • sunLight

    Beardtongue thrives in full sun situations, where it can receive at least 6 to 8 hours of direct sunlight daily. It can also tolerate partial shade, but too much shade can lead to weak growth and fewer blooms. The ideal spot is an area that is shielded from the hottest, most intense late afternoon sun.

  • thermometerTemperature

    Beardtongue prefers a temperate climate and can typically survive in temperatures ranging from 10°F to 90°F. However, the ideal growing temperature is between 60°F and 70°F. It's important that the plant is protected from harsh winter conditions, especially if temperatures dip below the survival range.

  • scissorsPruning

    Prune Beardtongue to remove spent flower stems, encourage bushier growth, and stimulate additional blooming. Pruning is often done after the first flush of blooms in the late spring or early summer. Deadheading throughout the growing season can also promote more flowers. Periodically check for and cut away any damaged or diseased foliage to keep the plant healthy.

  • circleLife cycle

    The life cycle of Penstemon 'Razzle Dazzle' begins with seed germination, often in late winter to spring, requiring well-draining soil and warmth to sprout. Once germinated, the young seedlings grow into vegetative plants, developing a rosette of leaves at the base and erect stems. Through the spring and summer, vegetative growth continues as the plant matures and produces lanceolate leaves along the stems. Flowering typically occurs from late spring to early summer, presenting vibrant pink flowers that attract pollinators such as bees and hummingbirds. After pollination, the flowers develop into seed capsules that mature by late summer or fall, dispersing seeds to complete the reproductive cycle. The plant may either die back in the winter, behaving as a herbaceous perennial, or persist in mild climates, preparing to enter the next growing season.

      Spring-Early Summer

    • The Penstemon 'Razzle Dazzle', commonly known as beardtongue, is typically propagated through seed or by cuttings, with the most popular method being through stem cuttings. To propagate beardtongue by stem cuttings, one would typically take 4-6 inch (10-15 cm) cuttings from soft, new growth in late spring or early summer. The cuttings should be snipped just below a node, and the lower leaves removed. Dip the cut end in rooting hormone powder to enhance root development and insert the cutting into a moistened mix of perlite and peat. The pot should be covered with a plastic bag or placed in a greenhouse to maintain high humidity. Roots usually develop within a few weeks, after which the cuttings can be transplanted to individual pots and grown on before planting out in the garden.
