Itoh hybrid peonies are an intersectional cross of woody stemmed peonies (“tree peonies”) and herbaceous peonies. Itoh hybrids retain traits of both of their parents but can be cultivated much the same as herbaceous peonies. They are traditionally grouped together with the tree peonies and listed in this catalog with tree peonies. They come in vibrant, unique colors and some of the best yellow varieties are still found with the Itoh hybrids.
