|Is it possible for Peonies to regrow if they are covered during the winter months? I covered mine with grass cuttings once and when I went to plant some again the next year, I noticed they were coming up and the stems were quite healthy.
|Your herbaceous peonies are perennial plants, and will sprout anew each spring. Winter protection is a must in cold areas, and as you've discovered, grass clippings make a satisfactory mulch. Once the clumps of peonies have become established they resent being disturbed, so leave yours as they are and they'll bloom triumphantly this summer.
