Red Rocks Beardtongue

Red Rocks Beardtongue (Penstemon x mexicali 'Red Rocks')

Red Rocks Beardtongue is a long-blooming perennial that adds bright rose-pink flower spikes and a clean, mounded form to sunny beds. It is a strong choice when you want dependable color through summer without a fussy routine, especially in well-drained soils. Hummingbirds and other pollinators find the tubular blooms irresistible, bringing more life to the garden. Once established, it handles drier stretches well, making it an easy fit for waterwise borders.

Distinctive Features

Upright stems rise above a dense mound of narrow, glossy green leaves, carrying showy tubular flowers in rose-pink tones, often with lighter throats, from early summer well into late summer and sometimes toward fall. The habit is slightly mounding and upright, giving the plant structure even before bloom begins. Foliage can be semi-evergreen in milder climates, helping the plant hold presence beyond the flowering window. Mature size is commonly around 12 to 18 inches tall for the foliage mound, with flower stems reaching about 24 to 36 inches, and a spread around 15 to 24 inches.

Growing Conditions

• Sun: Full sun to partial shade, with best flowering and strongest stems in full sun.
• Soil: Well-drained soil, including sandy or average soils, and avoid soggy winter conditions.
• Water: Low to moderate, water to establish, then provide occasional deep watering during extended drought.
• USDA Zones: USDA Zones 4 to 8.
• Mature Size: About 12 to 18 inches tall for foliage, 24 to 36 inches tall in bloom, and 15 to 24 inches wide.

Ideal Uses

• Focal Point: Use as a focal point in a sunny border where the rose-pink flower spikes can rise above companions and carry color through summer.
• Pollinator Gardens: Plant where hummingbirds and bees can work the tubular blooms throughout the season.
• Waterwise Borders: Use in well-drained beds and xeric-style plantings for strong color with less irrigation once established.
• Rock and Gravel Gardens: Tuck into sharp-draining sites where the mound stays tight and the flowers stand out.
• Cut Flower Beds: Grow for bright stems that add vertical color and texture to summer arrangements.

Low Maintenance Care

• Drainage: Prioritize sharp drainage, especially in winter, since wet soils can shorten longevity.
• Watering: Water regularly during the first season, then reduce to occasional deep watering during prolonged drought.
• Deadheading: Remove spent flower spikes to encourage continued bloom and keep the plant looking clean.
• Pruning: Cut back old stems in late winter to early spring before new growth begins.
• Transplanting: Plant where you want it long-term, since mature plants can be difficult to move once established.
