Penstemon heterophyllus 'Catherine de la Mare'
Height x Spread: 45cm x 60cm
'Catherine de la Mare' has gorgeous bell-shaped tubular flowers throughout summer, which are a blend of blue and purple. It is a semi-evergreen perennial with blue-green narrow linear foliage and a low spreading growth habit.
Do not be tempted to cut this perennial down before the winter, leave the top growth to protect it. In spring, after the last frosts have passed, cut the plant back hard. It can be used in a variety of situations including gravel gardens, coastal regions and rockeries. When planting in your flower borders ensure you choose a sunny location with a free-draining soil. A sheltered spot will encourage it to flourish.
