Intersectional Paeonia hybrids, common name Itoh’s are getting more and more popular. These peonies are produced by crossing herbaceous garden peonies with tree peonies, initially to create herbaceous peonies with pure yellow flowers.
Intersectional peonies offer the best qualities of both garden and tree peonies combined, including:

  • very large, tree-peony like flowers in colours not previous seen in herbaceous types
  • healthy, herbaceous foliage similar to tree peonies, but with a robust bushy habit that does not require staking
  • strong, herbaceous stems that hold the flowers upright even after a heavy rain and makes better landscape plant than older herbaceous peonies
  • a longer bloom time due to additional flowers being produced on side shoots
  • extreme winter hardiness like herbaceous types but with increased vigour
