Peonies, a resilient and long-lived perennial, have a history of popularity as a garden plant. They offer big, fluffy, fragrant flowers available in a diverse range of colors, forms and sizes.


There are three types of peonies, here’s a comparison:

‘Pink Hawaiian Coral’.

  • Handsome foliage — deep green in summer, bronze and purple in autumn
  • Don’t like to be moved
  • A mature plant can be 4 to 7 feet tall and 4 to 5 feet wide
  • Grow about 6 inches per year

‘Garden Treasure’


Zones: 4-9
Bloom time: June
Exposure: 5-6 hours of full sun per day
Planting depth: ½” in warm zones, 1 ½” in cooler zones
Fast Facts:

  • Hybrid plants that blend the perennial habit of herbaceous peonies with the sturdiness, giant flowers, and color range of tree peonies
  • Herbaceous in nature, dying back to the ground when winter comes
  • Often called Itoh peonies
  • Attractive foliage through summer and into fall
  • Good at the front of the border because they are shorter than tree and herbaceous peonies
  • Showy and don’t need staking


Amy Hall of Peony Farm in Sequim, Washington advises peony shoppers to choose varieties suited to their areas, but avows that every state has microclimate “pockets for peonies.”

Here are the facts you need to know when selecting peonies for your garden:

Herbaceous peonies:

  • Need a certain amount of cold weather to flower
  • There are garden-worthy varieties for Zones 2 to 8
  • Southern gardeners should favor early bloomers

Tree peonies:

  • Hardy from Zones 4 to 9
  • Don’t demand below-freezing temperatures
  • Do require a dormancy period
  • In regions where winter is a nonevent, dormancy can be forced by trimming off the leaves
  • Winter protection with burlap and a 3 to 4 inch layer of mulch (pulled aside in the spring) is wise in Zone 4 and colder parts of Zone 5

Intersectional peonies:

  • Die back to the ground when winter comes
  • Can be hardier than tree peonies
  • Are more tolerant of heat and humidity


In most locations, peonies will bloom in April, May or June. Expect tree peonies to bloom first (around Mother’s Day), followed by herbaceous varieties (around Memorial Day) and then the intersectionals. If you include all three types in the garden—tree, herbaceous, intersectional—you can enjoy the blooms for up to seven weeks.

Keep the following in mind:

  • Peonies planted in the fall (prior to the first frost) will have the best chance of blooming the following spring.
  • If you plant in spring, you may not see blooms for two years or more.
  • Most peonies only bloom once a year. However, a few tree peonies have been known to rebloom, including ‘High Noon’ and ‘Alhambra’.
  • Hall says it can take two to three years for a newly planted tree peony to get settled and start blooming well.
  • Many peony flowers change color as they open, so make sure to check them daily to appreciate their shifting hues.

Here’s how long each type of peony bloom will last:

  • Herbaceous peonies bloom for an average of 7-10 days depending on the cultivar.
  • If protected from the hot afternoon sun, the blooms of a tree peony can last as long as 14 days.
  • Intersectional peonies can produce blooms for a period of 3-4 weeks.


Picking the right spot to plant your peony is essential to its success. If sited incorrectly, deep roots make transplanting of mature peonies difficult or impossible. Aside from the proper amount of sunlight and nutrient-rich soil, you’ll want to make sure peonies are planted in an area where you can enjoy their gorgeous flowers. Furthermore, because peonies hate wet feet (roots standing in water), “a slope or raised bed is preferable to a very flat site,” says Kasha Furman of Cricket Hill Garden. And don’t forget to plan ahead and give tree peonies plenty of room—most grow to five by five feet in their 10th year.


Many peony flowers are fragrant. Their scents can differ between cultivars—some are scented sweetly of lemons, some have enticing citrus smells, and some are described as slightly spicy. Words like delicious and confectionary are often used to describe the smell of a peony. Decide how strong you want the scent—some peonies are lightly scented, while others have a heady fragrance. For example, Chinese tree peonies have a stronger fragrance than Japanese tree peonies.


Most peonies are sun-lovers. “They require almost nothing but full sun and patience,” says Kathleen Gagan of Peony’s Envy in New Jersey. However, tree peonies are an exception.

Herbaceous and intersectional peonies should be planted in a spot with at least five to six hours of full sun per day. However, plants that produce single and anemone flower forms may benefit from some afternoon sun protection.

Tree peonies prefer light shade during the heat of midday, which encourages the blossoms to linger 10 to 14 days, rather than fading in a blink (two to three days) in full sun. In China, parasols are enlisted to protect the delicate flowers from sun.


Some gardeners have success growing peonies in their native soil, but most experts recommend amending with organic matter before planting. Proper soil preparation will make it so you don’t have to fertilize for the first few years of your peonies life. No matter what, ensure that the soil is well-draining, peonies will not do well with soggy roots.

Here are some tips for improving your soil:

  • Herbaceous peonies love potassium; a 5-10-10 slow release fertilizer is a good choice.
  • Peonies are heavy feeders and strongly prefer a sweet or alkaline soil, which may require adding lime or wood ash. “The plant does not uptake the nutrients as well if it’s in an acid environment,” Furman explains.
  • Additional trace minerals (such as Azomite®) will inspire tree peonies to increase their flower size, bud count and ratio of double flowers, and to intensify flower color.


The depth at which you plant your peony will depend on the type of peony and your climate.

Here are the planting depths for each type of peony:

  • Herbaceous peonies: Position these with their “eyes” (next year’s buds) ½ inch (in warmer zones) to 2 inches (in cooler zones) below the soil surface.
  • Tree peonies: Plant deeper than herbaceous peonies. Gagan suggests digging a hole 2 feet deep and 1 foot wide (after amending the soil with organic matter). Position with the graft 4 to 6 inches below ground level, so that the “nurse” herbaceous peony rootstock will die away.
  • Intersectional peonies: Plant them just below the soil surface, 1/2 inch in warm zones, 1.5 inches in cooler zones.


Unlike roses, peonies do not require precise pruning to thrive. Often pruning is only necessary in the event of damage or disease. Both herbaceous peonies and intersectionals should be cut back at the end of the growing season. Cut your herbaceous peonies all the way to the ground, but leave 4 to 6 inches of stem on your intersectionals.

For tree peonies, a dense snarl of branches can lead to doom. After five years, remove suckers from the center of the shrub to thin out growth and promote better air circulation. Do not cut back tree peonies until they are well established—they are slow growing, so every inch is precious. Pruning during the first two to three years will just hinder their progress and slight you on next year’s display. When pruning tree peonies, take care not to cut the woody stems—they bloom on old wood.


Peonies do not need regular division for successful blooming. However, if you’d like to have more peonies, you can divide your mature plants as a form of propagation. The best time for dividing peonies is in the fall when the plant is nearing dormancy. Roots cut into pieces with 3-5 eyes have the best chance of success.


Many peonies should be staked to support heavy blooms, especially if you live in a rainy climate. Herbaceous peonies can be supported with a peony ring, while tree peonies are more suited for the use of bamboo stakes and natural twine. If this sounds like too much hassle, there are many varieties of peonies that feature strong stems that don’t require staking.


Peonies are not overly thirsty plants—in fact, overwatering can lead to problems. Give your peonies excellent drainage and begin watering in spring if you go more than two weeks without rain. Then, provide weekly, deep watering throughout the dry summer months (one inch at each watering). Continue watering after flowering to ensure vigorous plants the following year. There is no need to water once they have gone dormant.


In very cold climates, peonies may benefit from a loose winter mulching with organic matter such as pine needles or shredded bark. Keep mulch a few inches away from the base of the plant. Remove the mulch in spring to allow new growth at the soil surface.


Peonies are happiest in the garden, but can be grown in pots if given the proper attention. Select a large container with plenty of drainage holes. In colder areas, bring potted peonies in for the winter to protect them from freezing temperatures; plants in containers are more susceptible to frost damage. Additionally, you will need to water more frequently during the growing season, as containers dry out quickly.


Many gardeners have difficulty understanding why their peonies don’t bloom. Here are the most common reasons:

  • They are planted too deeply
  • There isn’t enough sunlight
  • Your soil is heavy on nitrogen
  • The plants are still young
