As far as I know, Coral Sunset, Coral Charm, Cytherea, and Joker have readily formed eyes from blind root pieces for me. These peonies produce eyes in less than a year's time. Coral Sunset even bloomed within a year from newly formed eyes if the roots were large to begin with. I had some Alexander Woollcott blind root pieces that I buried from last fall. I will report back if any of these roots produce eyes.
