Penstemons have a long flowering season, from midsummer till the first frosts. The Autumn flowering is spectacular and a bright show is guaranteed.
The snapdragon like blooms come in shades of blue, white, pink, red and purple.
An easy plant to grow, the Penstemon should be planted in a sunny/semi shaded site in free draining soil.
Penstemons are normally perfectly hardy in most parts of Great Britain and zones 5 and above in North America. As an insurance policy it pays to overwinter a few autumn struck cuttings in a cool, but frost-free area.
The following varieties are reliable.
Penstemon " King George V": Handsome crimson flowers with a white throat. 3 ft.
Penstemon "Appleblossom" : Baby pink and white" 3 ft.
Penstemon " Burgundy" : Deep red. 2 ft.
