I got some tiny penstemons a few years ago from an T&M, size of my thumbnail. Two maybe three years later, I've got some lovely pushy plants now. I moved mine last year and think I cut them back hard in the Winter/early Spring.
Good news on your cuttings Matt. I've taken cuttings for the first time this year. The new growth on yours sound promising No growth on mine,but they haven't keeled over and died so I'm hopeful
