Dakota Burgundy Beardtongue (Penstemon digitalis 'TNPENDB')

Dakota Burgundy Beardtongue brings bold, dark foliage and a long run of soft, airy flower spikes to sunny beds without demanding constant care. The deep burgundy to purple-black leaves add season-long contrast, while the tubular blooms keep borders looking lively through summer. Its compact, upright habit fits easily into mixed plantings where you want strong color without a bulky footprint. Once established, it handles heat and short dry spells well, making it a reliable performer for real-world landscapes.

Distinctive Features

This selection stands out for its glossy, very dark foliage that holds color well through the growing season, topped by spikes of tubular flowers in lavender to violet shades. Bloom typically peaks in early to mid summer and can continue with additional flushes depending on conditions and cleanup. The stems are generally sturdy for a penstemon, giving you a cleaner, more upright look with less leaning. After flowering, darker seed heads can add extra texture into late season.

Growing Conditions

• Sun: Full sun to part sun for best flowering and the darkest foliage color.
• Soil: Well-drained soil is essential, and average to lean soils often produce the best form.
• Water: Water regularly to establish, then water occasionally; drought tolerant once established.
• USDA Zones: 3 to 8.
• Mature Size: About 12 to 18 inches tall and 16 to 18 inches wide, with flower spikes commonly reaching about 18 to 24 inches tall.
• Notable Traits: Attracts hummingbirds and pollinators, and is often tolerant of browsing once established.

Ideal Uses

• Focal Point: Use the dark foliage and violet-toned flower spikes as a focal point in a sunny border where contrast matters.
• Border Structure: Adds upright lines and clean shape among mounding perennials and ornamental grasses.
• Mass Planting: Plant in repeating groups for a bold foliage ribbon and a stronger summer bloom show.
• Pollinator Gardens: Supports bees and hummingbirds with tubular summer flowers.
• Containers: Works well in large pots where the dark leaves add depth and the flowers lift the arrangement.

Low Maintenance Care

• Pruning: Cut back old stems in late winter to early spring to encourage fresh, tidy growth.
• Deadheading: Remove spent flower spikes to keep the plant neat and encourage additional bloom.
• Watering: Avoid soggy soils, and water deeply only when soil has dried several inches down.
• Feeding: Keep feeding light, since overly rich soil can reduce flowering and soften stems.
• Spacing: Provide airflow and avoid overcrowding to support healthier foliage and stronger stems.
