I don't know what your definition of "reasonable" is, but Khlem's Song Sparrow sells this peony for $26.95. That may seem "unreasonable", but consider the fact that you will be buying the peony directly from the hybridizer (Khlem), which will guarantee you get the peony you want. They do guarantee their plants to be true to name, and all of the peonies I have gotten from them have bloomed their first spring.
