Intersectional 'Itoh' Peonies

The Japanese nurseryman Toichi Itoh was the first to succeed in hybridizing tree peonies with herbaceous peonies in the 1960s. From this new hybrid group, also known as Itoh peonies, a vibrant palette of colors emerged. A few American hybridizers have been exceptionally successful in making these difficult crosses. We are pleased to offer a selection of these unique American hybrid peonies. Intersectional peonies possess many attributes which make them highly desirable landscape plants. The leaves and flower forms resemble those of tree peonies, while the growth habit is similar to that of herbaceous peonies. Flowers are held upright on top of the bush and never require any kind of support. In the fall, after the frost, intersectional peonies are cut back to ground level, and the plants come back larger each spring. Most bloom with the mid to late season herbaceous peonies,usually peaking in our USDA zone 6a garden in the first week of June. Proven to thrive in USDA zones 4-9, intersectional peonies require well-drained fertile soil and full sun. See the Learn section for complete planting and care instructions.
