Penstemon 'Dark Towers' (Beardtongue)

Penstemon 'Dark Towers' is a stunning perennial known for its combination of deep burgundy foliage and tall spikes of tubular, pale pink to lavender flowers. The glossy, dark leaves retain their rich color throughout the growing season, providing a dramatic contrast to the delicate blooms. Its upright growth habit makes it an excellent choice for adding vertical interest to borders, cottage gardens, and mixed perennial plantings.

Penstemon 'Dark Towers' thrives in well-drained, moderately fertile soils and is drought-tolerant once established. It attracts pollinators such as bees, butterflies, and hummingbirds, making it a valuable addition to wildlife-friendly gardens. Deadheading spent blooms encourages prolonged flowering, and cutting back in late fall or early spring promotes fresh growth. This versatile plant pairs beautifully with ornamental grasses, sedums, or contrasting sun-loving perennials like echinacea and rudbeckia for a bold and dynamic garden display. Its low-maintenance nature and rich foliage make it a standout in any garden.
