Intersectional hybrid peonies are produced by crossing herbaceous peonies with tree peonies. Intersectional peonies are also known as ITOH hybrids – named after Mr. Toichi Itoh, the first to successfully cross tree peonies with herbaceous peonies.
Intersectional peonies exhibit tree peony flowers and foliage on plants that are herbaceous in habit. They come in many colors and shades, but yellow is the most common color. Intersectional peonies are cut down in the fall and generally treated in the garden as herbaceous peonies.
They generally have strong stems and a full rounded habit so they do not need staking. The flowers tend toward semi-double and many are fragrant. These showstoppers are rugged, deer-resistant, drought-tolerant and more difficult to propagate than herbaceous peonies, hence the relative price.
