Calico Beardtongue

Penstemon calycosus

Calico Beardtongue, also called Long-Sepal Beardtongue, is a perennial native to the eastern United States, particularly valued for its vibrant floral display and wildlife benefits. This species typically reaches 2 to 3 feet in height and features clumps of glossy green leaves. The plant's most notable attribute is its purple, tubular flowers, which are spotted with white on the inside, giving them a distinctive calico appearance. These flowers are borne on tall spikes and are highly attractive to pollinators, including hummingbirds and butterflies, making it an excellent choice for pollinator gardens, perennial borders, and naturalized areas.

Maintenance Tips

  • Drought-tolerant once established; water regularly during the first growing season and during prolonged dry periods thereafter.
  • Deadhead spent blooms to encourage additional flowering and prevent self-seeding, if desired.
  • Prefers well-drained soils and is tolerant of a range of soil types, including clay, if drainage is adequate.
  • Apply a light layer of organic mulch to conserve moisture, suppress weeds, and maintain a clean appearance around the plant base.
  • Monitor for pests such as aphids and diseases like powdery mildew, especially in humid conditions. Provide good air circulation and avoid overhead watering to minimize disease risks.
