Penstemon 'Heavenly Blue'
Penstemon 'Heavenly Blue' is a bushy semi-evergreen perennial boasting incredibly pretty, bell-shaped, electric blue with lilac undertones. Grows to a height of 40cm.
Penstemon are extremely hardy and a reliable performer in the heat of summer, plus they are frost tolerant, makes these beautiful cottage perennials suitable for a wide range of positions and soils.

Maintenance is simple, lightly prune at the start of each spring.
Excellent cut flower.
