Bartzella is a cross between a herbaceous and a Tree Peony (known as Intersectional or Itoh Peonies), a horticultural feat that has proved remarkably difficult to accomplish. As a result, the Peony Bartzella, is a stunningly beautiful variety whose deep sulphur yellow flowers, each with red flames at the center, are carried on a plant that looks and behaves like a very big, healthy herbaceous Peony. Bartzella has huge flowers on strong stems, above rich green foliage.
There are very few yellows in the herbaceous Peony world, and none can compare with 'Bartzella' in beauty or performance.
