Roger Anderson 1986. Itoh. Large 9″ semi-double blooms. Lemon yellow with touches of red in the center. In three years you will marvel at the bud count. The first yellow peony we saw on the market was named Garden Treasure and it routinely sold for $125-$150. It’s still the standard for yellow although there are other yellows now. We do not sell Garden Treasure but do sell Lemon Chiffon as well as Bartzella featured here.
