Thanks everyone! I am happy to hear that it is a good performer, Tracey. Next year, I will let some flowers go to seed. I wonder what I would get if I cross this with Yaezakura which blooms at the same time as the JR TP.
LG, I bought this tree peony from a peony collector and grower who said that he purchased this from Roy Klehm at SongSparrow. So if you bought the semi-double form of the Joseph Rock TP from SongSparrow, then it will be the same as mine. He sold me a division of his TP so that may explain that I get the puff of pink petaloids in the center. The mature stems give me this form but the young stems give me the semi-double form.
