A year or so ago all of my peonies had nice red pips showing as we headed into winter. Many other growers reported the same thing. None were hurt and all bloomed the following year. I have four roots with 6" stems that I stuck in a pot last fall. All four had pips which is what prompted me to do so. They have gotten a bit larger over winter in the dark crawl space which has held at 55 and now down to 50 (weather has finally gotten cooler - in the teens and low 20's) as the outside temp affects the crawl space temp despite insulation around the edges and closing up the vents. I store dahlia tubers down there and last year one pot of lilies which insist on growing. drat.
