I'm almost positive that this is Rocky Mountain Penstemon, but would like another opinion, just to make sure. If it is, I'll be thrilled! I found this growing wild a couple of miles from my house, and would love to take some cuttings from it. I just don't know how to go about doing that. What I found online said to take soft stem cuttings in early summer. I'll be going back to look for seed later, but would love to get started before then! There were a few dried seedheads, but no seeds in them from what I could tell.
