It should be watered deeply once a week, providing about 1 inch of water which roughly translates to 0.6 gallons per square yard of soil. Ensure the soil is well-draining to prevent waterlogging. During hot, dry periods, you may need to water twice a week. Reduce watering in the fall as the plant prepares for dormancy, and water sparingly in winter only if the soil is completely dry.

  • circleLife cycle

    Beardtongue 'Andenken an Friedrich Hahn' begins its life as a seed, which upon finding suitable conditions, germinates and grows into a seedling. The seedling then develops true leaves and establishes a root system as it enters the vegetative stage, during which it grows steadily. When mature and environmental conditions are favorable, usually in spring or early summer, the plant enters the flowering stage, producing tall spikes of tubular, deep burgundy flowers that attract pollinators. After pollination, flowers develop into fruit capsules containing numerous small seeds. As the growing season ends, the plant may die back, especially if it is grown in a colder climate, entering a period of dormancy. The cycle is completed when the plant resumes growth from the rootstock or seed the following season, depending on how it overwinters and the conditions of its habitat.

      Spring-Early Summer

    • The Penstemon 'Andenken an Friedrich Hahn', also known as Beardtongue, is commonly propagated through stem cuttings. This method is particularly popular due to its effectiveness and relative simplicity. To propagate Beardtongue using stem cuttings, you should ideally take cuttings in late spring or early summer when the plant is actively growing. The cuttings, which should be about 3 to 5 inches (approximately 7.6 to 12.7 centimeters) long, are taken from healthy, non-flowering stems. Each cutting should have several leaf nodes, and the leaves on the lower half of the cutting are removed. The base of the cuttings should then be dipped in rooting hormone powder to encourage root development and then placed in a well-draining soil mix. Provide consistent moisture and maintain a warm environment to help root formation, which typically takes several weeks. Once the cuttings have rooted, they can be transplanted into individual pots or into the garden.
