Dark Towers Beardtongue

Dark Towers Beardtongue (Penstemon 'Dark Towers')

Dark Towers Beardtongue brings rich, dark foliage and soft pink flower spikes to sunny beds for a look that feels bold but still refined. The deep wine-purple leaves hold their color well through the season, giving you contrast even when the plant is not in full bloom. Pale pink tubular flowers rise above the foliage in late spring into summer, adding height and pollinator activity without making the border feel heavy. It is a reliable perennial for gardeners who want strong color, tidy structure, and easy performance in heat.

Distinctive Features

This beardtongue is prized for its glossy, burgundy to purple foliage and upright spikes of pale pink, tubular flowers that create a clean vertical accent. The clumping habit stays more controlled than many tall summer bloomers, making it easy to tuck into mixed borders without crowding neighbors. Flowers are especially attractive to hummingbirds and butterflies, and the plant often keeps a dark, dramatic presence from spring through fall. In well-drained soil, it offers strong durability with a modern, high-contrast look.

Growing Conditions

• Sun: Full sun for best flowering and the darkest foliage color.
• Soil: Well-drained soil is essential, and average to lean soils often produce the strongest stems and best bloom.
• Water: Dry to medium moisture, water to establish, then water occasionally during extended dry periods.
• USDA Zones: 3 to 8.
• Mature Size: About 2 to 3 feet tall and 1 to 2 feet wide.
• Notable Traits: Attractive to hummingbirds and butterflies and often tolerated by deer.

Ideal Uses

• Focal Point: Use the dark foliage and pink flower spikes as a focal point in a sunny border where contrast can anchor the view.
• Border Structure: Adds upright lines and a clean silhouette among mounding perennials and ornamental grasses.
• Mass Planting: Plant in repeating groups to create a ribbon of dark foliage that looks intentional all season.
• Pollinator Gardens: Supports hummingbirds and beneficial insects during its bloom window.
• Cut Stems: Provides sturdy flowering stems that add height and softness to summer arrangements.

Low Maintenance Care

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