Jerry, would you remind me what your soil formula is? I finally purchased some species and fernleafs and know I need to amend my soil for success. I have had a hybrid fernleaf for five or so years but it doesn't have the fine leaves. More like a regular peony. I got it from Adelman's and it was simply called "fern leaf hybrid.' We have two at the botanical garden that I think are mislabeled. I will take pics this spring and post. Perhaps you can help us get the right labels on them.
