Penstemon Midnight puts on a great show of
dark purple flowers from mid Spring through Fall. The plants are at
their best for two to three years but they do a tremendous job of quickly
filling in a young garden or a newly opened space. I trim off the
dead flowers and cut Penstemon Midnight back heavily in the late winter. If
the plants air-layer on their own they get a new lease on life. Penstemon
Midnight
will survive Winter temperatures down into the low teens. I have sometimes had
trouble with mites and have cut off the affected portions to fairly good success.
Penstemon Midnight blooms best in full Sun.
