Penstemon heterophyllus 'Heavenly Blue'

Penstemons produce foxglove-like flowers, which look fantastic in informal and cottage garden schemes, and are extremely attractive to bumblebees.

They thrive in full sun to partial shade, in moist but well-drained soil. Many penstemon varieties are hardy in all but the harshest winters, but do move plants under cover or take summer cuttings if you want to make sure your plants will last through winter.

Penstemon ‘Heavenly Blue' bears pretty, tubular flowers that are an intriguing blend of purple and blue, appearing from May to October. It’s ideal for growing at the front of a sunny border, or in pots on the patio.Plants may need protection in colder regions. Apply a thick mulch of well-rotted manure or compost in autumn to protect the roots. Plants can be propagated by seed but they won’t come true. For better results, divide Penstemon ‘Heavenly Blue’ in spring.
