Imparting a strong sculptural presence, these selections are 3-year biennials that thrive in moderately moist well-drained spots. If you cut the blooms before the seed sets, you might be rewarded with flowers for 3 or even 4 years.
Painted in vivid tones of deep plum, the round buds open into extraordinary domed flowers that reach an astonishing 8 in. across and, set against burly, freely branching burgundy stems plus vigorous green foliage, possess a dark magnetism. Give this Korean native plenty of room as it rockets skyward. Penstemon ‘Blackbird’ provides an echo of bloom color while delivering vertical contrast.
Size: 4-1/2' – 5' 0" high x 2-1/2' wide.
Hardy to zone 5.
