Intersectional Peonies
Paeonia x 'Bartzella'. Bartzella is one of the earliest of the intersectional or Itoh Peonies to come on the market some 10-15 years ago (it was introduced in 1986 but didn't become readily available until much later). The intersectional Paeonies are a cross between herbaceous peonies and tree peonies. They offer the hardiness, vigor, and ease of care of herbaceous peonies while also offering the tremendous range of colors available in the tree peonies. Intersectional Paeonies can be found in every shade and color ranging from rich orange/yellow through deep purple - colors that were formerly unavailable in herbaceous peonies. They also have exceptional form and structure, with strong stems that hold the flowers upright.
When they first came on the market these intersectional/Itoh peonies were hard to find and prohibitively expensive, but each year makes them more accessible to the everyday gardener.
These are tremendous plants that I believe deserve a spot in every sunny garden.
