Such a unique color for a peony!  This elegant selection produces an attractive array of large 8”, semi-double to double flowers that start out soft copper rose and age to soft gold with a deep burgundy flare in the center.  Both flower colors are present on the clump at once and flowers are produced on both the top and sides of the clump .  These strongly fragrant blossoms are wonderful in fresh bouquets. 

Its healthy green foliage similar to that of a tree peony forms an impressively sturdy clump that is substantial enough to be grown in place of a small shrub in the landscape.

Intersectional peonies are a relatively new class of Paeonia created by crossing herbaceous garden types with woody tree types.  They are often called “Itoh Peonies” because the original cross was first made successfully by Japanese nurseryman Mr. Toichi Itoh in 1948.  Sadly, he passed away before ever seeing one of his crosses bloom.  Since that time, other hybridizers have continued his work including American breeder Roger Anderson.

Intersectional Peonies offer the best qualities of both garden and tree peonies combined including:

  • Very large, tree peony-like flowers in colors not previously 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; makes a 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 vigor

Homeowner Growing & Maintenance Tips:

The most critical aspect of planting peonies is proper planting depth. For intersectional peonies, the crown should be planted 1½ - 2 inches below soil level. If the eyes have already begun to grow, they may stick up above the soil a bit after planting the crown below soil level.

A permanant, sunny or partly shady site is ideal for intersectional peonies. Protection from afternoon sun and from harsh winds will help to prolong the lives of the the exotic flowers. Peonies will perform best in well-drained, evenly moist, rich soil with a pH near neutral and they are drought-tolerant once established.

An annual topping of compost is recommended each fall. Though peonies may be slow to establish, you can be assured that they are developing a deep, substantial root system which will help to produce flowers that are well worth the wait. Once established, peonies can live 50 years or more.
