Penstemon 'Sour Grapes'

AGM. An upright semi-evergreen perennial with tubular purplish-blue flowers with a whitish throat, and glossy green, lance-shaped leaves. Flowers over a long period. Jun-Oct. H75cm S45cm. This is the true plant which is often mis-named.

Care Instructions

Penstemons prefer a fertile soil in a warm, sunny or lightly shaded spot. May need winter protection (a dry mulch is best) in colder areas. Removing faded flower stems regularly will prolong the flowering period. They should be cut back in late spring. Loved by bees.
