Abundant Sky Blue Blooms - Penstemon Heavenly Blue produces elegant spires of soft sky blue, bell-shaped flowers that bloom repeatedly from early summer into autumn. The tall flower spikes add graceful vertical interest to borders and attract pollinators such as bees and butterflies.
-
Ideal for Sunny Borders & Cottage Gardens - This hardy perennial thrives in full sun and well-drained soil, making it perfect for mixed borders, cottage gardens, and wildlife-friendly planting schemes. Its airy growth habit pairs beautifully with ornamental grasses and other summer flowering perennials.
-
Low Maintenance & Long Flowering - Heavenly Blue is easy to grow and relatively drought tolerant once established. Regular deadheading encourages continuous flowering, providing long-lasting colour throughout the growing season with minimal care.
This plant can tolerate being plant in a South or West facing position in the garden in full sun to partial shade.
Regular watering
This plant is best planted in a sheltered area of the garden, in moist well drained soil. This plant requires protecting in colder areas over the winter using dry winter mulch.
