Intersectional Peonies are hybrids between woody Tree Peonies and herbaceous Garden peonies. These hybrids are relatively new creations, with the first successful intersectional crosses being made in 1948. These hybrids are called “Itoh peonies” after Mr. Toichi Itoh, a Japanese hybridizer who created the first intersectional Peony. the result is a disease resistant plant with a longer blooming season, due to their ability to produce preliminary and secondary buds once the plant is established. Its lower compact habit and sturdier stems allows it to support up to 30 flowers per well-established plant.

Intersection, or “Itoh” Peonies are very easy to grow in full to part sun in well-drained soil. Make sure the crowns are planted 1 to 2 inches deep and no deeper. If peonies are planted too deep, they may not bloom.

Planting Peonies

Adding peonies to your garden is easy. Plant in full sun in most regions. In colder regions, planting peonies in shade will result in weak stems and less flowers. In warmer regions or where spring is hot and dry, choose a site with afternoon shade. Plant in average or well-draining loamy soil. Peonies prefer soil that provide moisture, but isn’t water logged. Add compost if needed before planting.

Planting Steps for Herbaceous and Intersectional (Itoh) Peonies

  1. Choose a site with well-drained soil away from any competing roots. Peonies thrive if left to grow undisturbed in the same location for years.
  2. Dig a hole 12" wide and the length of the roots. This is the time to add any compost in the bottom of the hole. Plant the roots 1" to 2" below the soil level with the eyes (buds) pointing up. If you are planting more than one, plant 2-3 feet apart to allow enough space. If planted to deep, the peony will lack blossoms. Visit our planting guide for a detailed description
  3. Slowly back-fill around the roots, not allowing any air pockets, adding pressure to compact the soil.
  4. Once planted, gently water around the plant. Add a light mulch or chopped leaves to reduce weeds and to regulate soil temperature and moisture. Water every day for 5 days in the morning or evening, unless it rains or there is lots of moisture. Be sure not to over water, as the roots will rot.

Planting Tree Peonies

Planting tree peonies is different than herbaceous and intersectional itoh peonies.

  1. Choose a site with well-drained soil away from any competing roots. Tree peonies thrive if left to grow undisturbed in the same location for years.
  2. Dig a hole the length of the roots roughly 2 feet deep and dig it wide enough to accommodate the roots with some room to grow, roughly 1 foot wide. This is the time to add any compost in the bottom of the hole. If you are planting more than one, plant 2-3 feet apart to allow enough space.
  3. Slowly back-fill around the roots, not allowing any air pockets, adding pressure to compact the soil.
  4. Once planted, gently water around the plant. Water when needed, the best practice is when the soil has dried out and or it hasn't rained. Tree peonies need water to generate root growth, but if over watered, they will rot.

Aftercare

The first year of growing peonies, expect the roots to products 2-5 leave shoots and 1-2 flowers. Year two brings a plant double the size and double the blossoms. By the fourth or fifth year peonies will be full and bushy, with lots of foliage and blossoms.

Staking

Itoh and tree peonies don't require staking, but most herbaceous peony once established, produce heavy flowers that often are too heavy for its stems. You don't have to stake them, but if you don't, you're going to have big beautiful flowers nodding down. So once you have a healthy clump, use peony rings to keep them upright. The rings are simply wheel-like wire arrangements that stand up over the peony like a little wire table as the plant sprouts in the spring. With upright supports, the peony ring is placed so the shoots will grow up through the round wire bale. Of course, the foliage quickly hides the ring, and you have a beautifully-supported clump well before the flowers open. Where to find Peony Rings? We recommend Gardeners Supply.

Pruning/Trimming

For herbaceous and (itoh) intersectional peonies after blooms have passed, clip expired blooms down to the where the foliage meets the stem. Leave the foliage for the remainder of the growing season. As fall arrive and temperatures cool, the leaves will turn yellow and then wilt. For herbaceous peonies trim back all foliage to about 3" from the ground. This keeps the plant tidy and allows new growth to come up without damaging it. In the fall itoh peonies need to be treated similar to herbaceous and tree peonies since they are a hybrid of both. Once the plant has matured its best to trim back so that the herbaceous portion of the stem is removed and the hard wood portion remains. Its best to leave the peonies alone in there first year of growing so that you tell the difference between the herbaceous green stem from the hard wood portion as the leaves die back. Usually mature itoh peonies will leave 4-5 inches of hard wood above ground.

Tree peonies require different trimming techniques. Cut the stem just below the expired blooms. If you trim the stem to far, it will hinder next year's growth. This years green shoots will become next years woody branch. So in the fall, do not trim back or cut to the ground, leave the shrub as is. If you have a mature tree peony and it needs shaping, the best time to prune, is right after it blooms. Make sure to not take to much off the tree as it can really hurt the shrub.

Fertilizer

Peonies don’t need to be fertilized every year. Its best to plant them with plenty of nutrients. Apply bonemeal, compost or well-rotted manure in early summer, after peonies have bloomed every couple of years.

          USDA Hardiness Planting Zones

          To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

          • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
          • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
