Dear Jane, P.mloko may one of the most frustrating of species peonies to grow. Part of this is due to the repeated 'insistence' that flowers are 'picture perfect' 'moonlit yellow'. But the species is quite variable and Prof. Hong De Yuan is his most recent monograph on the genus has helped to clarify the mess. In the wild plants can be found bearing a rage of colors from picture perfect pale yellow to bright glowing pink and all combos in between. And there are a range of closely related forms all now in the species P. daurica. You may be familiar with some subspecies formerly considered true species such as P. d. macrophylla, P. d. wittmanniana, P. d. coriifolia and of course P. d. mlokosewitschii. Add to this the ease of which all these hybridize and the known effects of temperature ( possibly due to your recent move and change of climate) and plant age on flower color and you have a range. I have a friend in up state NY who grows a few different wild accessions together, gets all kinds of mix and match and refers to them as his 'Molly Mutts', an apt description. If you MUST have a good reliable pale yellow, you have to see the plant in bloom and buy from that seller. Or grow a lot of seedlings and select ruthlessly. Or have good luck in buying a small plant. In your area you might inquire from Paige Woodward of Pacific Rim Native Plants, Diana Reeck of Collector's Nursery, Carol Adelman of Adelman Nursery or just ask around as it is somewhat more available in OR and WA in the PNW. (Heritage Seedlings offer seedlings at a wholesale rate if you need LOTS). Fortunately any color it is a very nice plant. Best Jim W.
