Purchased this peony from G.H. Wild & Sons in 2011 (on sale for $15).
It is supposed to be a RARE pale yellow single, 28 inches tall and a very early bloomer.
It opens with a slight pink tint, fades to pure white, 42 inches tall and blooms in midseason. All of my "early" peonies bloomed a couple of weeks ago.
I brought this to the attention of G.H. Wild last year and sent them photos. They responded that it looked like 'Claire de Lune.' Since this is a 1954 White - Wild & Son introduction, you would think they would get this right.
