Got this sent to me. Don’t know which cultivar or species but if I were to guess I’d say ‘High Noon’. That Lutea hybrid cultivar has the ability to give some rebloom in some years.
“I wanted to share a photo I just took of a re-blossoming peony on a peony bush that normally blooms in late May or early June. Two new buds emerged this week. This also occurred with just one blossom on the same bush at the same point in time 5 or 6 years ago.
Best,
Jennifer”
