Itoh peonies (also known as intersectional peonies) have a mix of traits of two Peony varieties: the hardiness of traditional garden peonies, and the upright growing style and prolific blooms of tree peonies. Peony Itoh All That Jazz is a deer-resistant peony and a prolific bloomer growing 50 flowers per plant at times. The magenta-speckled petals are a customer favorite, and the fact that they are very low maintenance helps matters, too! Full sun to light shade is best for these beauties. They definitely make you want to sing and dance!
