Penstemon 'Arctic Fox'
Penstemon ''Arctic Fox' is an upright perennial to 60cm tall, with lance-shaped leaves and clusters of small upright bell-shaped pure white tubular flowers. This hardy evergreen plant is best left until early spring after the risk of harsh frosts has passed before pruning back any dead stems and excess growth, although can be pruned by a third in early autumn if likely to be damaged by winter winds. Will tolerate any well drained soil, in sun or part shade. In colder areas protect with a dry mulch in winter.
