Penstemon 'Sour Grapes'

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.
