This is an older pic, have more current ones on my phone, but shows how the peonies are doing in the mix as I described. I'll try to post a pic I took in the spring where I moved all of the tree peonies and Itohs to a different spot, more grouped to make sure all of those get planted this fall. This pic shows other perennials as well. Some of those perennials are just in normal soil, just depends on what I had on hand when I dug those.
