Hi Teresa, just sent a treemail, got my daylilies today! Thanks again!
I haven't deliberately grown any tree peonies from seeds but I did notice 3 tiny seedlings from Phoenix White this year. None of my other tree peonies have bloomed before this spring and only had a few blooms, no seed pods at all on those. I actually bought peony seed from the APS annual convention last year, the guy manning the desk gave instructions on planting them outside which is what I did. I haven't had any of the tree peony seeds sprout yet but I planted them in big plastic pots with the bottoms cut out so I can see exactly where they are. I'm waiting for at least another year before I call it a total failure on the tree peony side, have had several herbaceous sprout from that same group. If you plant outside put them in a shadier spot than you'd plant a peony in typically, then move it after the 2nd or 3rd year after sprouting. You can plant the same fall you collect the seed.
