Propagating Husker's Red Penstemon
You can propagate 'Husker's Red' simply by gently pulling the stalk away from the mound and replanting. If there is resistance water the penstemon and they should pull away very easily. The group of plants you see in the above picture started as 4-5 small sprigs that were removed from another location in the yard. I spaced them at about 8 inches apart and let them merge together around a bird feeder in the front garden. I wrote a post about this propagation technique for 'Husker's Red' Penstemon two years ago if you would like more information on propagating this penstemon.
Do you have 'Husker's Red' Penstemon in your garden?
