Intersectional peonies are a hybrid cross between a tree peony and a herbaceous bush peony. Their flowers are similar to tree peony flowers and their growth habitat is that of a bush peony. They grow every spring and are cut back to ground level in the fall. They never need staking and are exceptional garden and landscape perennial plants. It is not uncommon to have 70 or more blossoms on a mature plant. Most are pleasantly fragrant!
They are commonly referred to as Itoh peonies - Mr. Toichi Itoh was the first successful breeder of these intersectional peonies.
