Jim McKenney wrote that his Paeonia lutea died after being moved. I suspect that a mature seed-grown plant of this species would not take kindly to being moved. Even the young seedlings, 10-12 inches tall, that I move from under the big ones don't always survive the experience. I have this species in several sites, including volunteers in perfectly awful places such as the root zone of a big Douglas fir. It seems to flower best in half shade, but even a plant in full shade up against the north side of my house blooms and sets seed. It's definitely hardy to zero F or a bit below. Regarding herbaceous peonies that can grow from bits of root left in the soil, the pretty variety 'Coral Charm' is well known for doing this. I have a bunch of them popping up among the branches of a prostrate pine that I planted after moving (I thought) the peony. Jane McGary Northwestern Oregon, USA
