Notable characteristics: Orchid-lavender petals are accented by dark burgundy central flares. Large, matte green, foliage is similar to that of many hybrid tree peonies.
Bill Seidl of Manitowoc, Wisconsin was a prolific breeder of hybrid peonies. 'Ann Marie' is unique in that both its parents were yellow peonies. Bill thought so highly of this plant that he named it after his mother. This cultivar readily sets seeds when hand pollinated and is of particular interest for future tree peony breeding.
