Intersectional Peonies with Above Ground Buds
I received this question from Joy in zone 8a:
"First and foremost, thank you for having a most informative website on one of my most loved flowering plants."
"I am writing to you today, as I’m just now getting out into the garden and tidying up my peonies, which I usually cut them back in the fall. I noticed that my Itoh Peony Julia Rose (I have 2 and planted them in 2012) have developed eyes on last years dead stems and as normal, eyes also stemming from the ground. I’ve never seen this before and thought perhaps that it was a result of not cutting them back in the fall. I’m not sure how to proceed with spring clean up and thought to seek your most valuable advice."
"Thank you for your time and look forward to your guidance."

Actually intersectional (also called Itoh) peonies can grow and bloom from woody stems grown in previous years (especially in our warmer Southern climates). I actually did an experiment to see what would happen with those stems, 2011 Peony Experiments - Intersectional Blooms. So when you are cleaning up your intersectional peonies that have woody stems in place, be sure to keep those stems where you can visibly see a red growth bud at the top. Then just pick off any old leaves or foliage from that stem. For all of the other stems, cut them back to the first red growth bud that you see. You can make the cut a little above the growth bud, leaving an inch or a half inch or so.
I usually wait to cut back my intersectional peonies later than the rest of my peonies, usually late winter (sometimes early spring if I'm really behind). It is possible that some of those above ground stems could get killed over the winter and some may not. By waiting to cut them back later in the winter season, you'll then know which ones will grow and which ones were killed. That way you can cut back any that didn't make it. If I do happen to cut my intersectional peonies back early (in late fall), then I generally leave all stems with buds on them, cutting them back to the first pink bud. Sometimes they don't all make it through the winter, though.
I hope you enjoy your 'Julia Rose' Intersectional Peonies this spring! Take Care and Happy Growing!
