An Itoh or intersectional hybrid peony is a cross between a tree and an herbaceous peony. The foliage and flowers reveal their tree peony ancestry. Their growth pattern, however, is similar to the herbaceous peony. Foliage remains healthy until the first frost. The Itoh peony is an asset for every garden.
