The peony has the fattest, most delicious petals and rich green foliage, making it outrageously attractive when it is in bloom. From spring to summer, savor stunning floral displays. Learn how to care for, grow, and plant peony.
About Peonies
Peonies are a perennial that will steal your breath away every year. The plants may even outlive you—some have been reported to survive for at least a century.
When Is Peony Season? When Do Peonies Bloom?
Depending on your location and the kind you are planting, peonies bloom from late spring to early summer.
You may extend the peony season across several weeks and take use of those magnificent blossoms for as long as possible thanks to the abundance of nurseries that provide early, midseason, and late blooming types.
Peonies may thrive as far south as Zones 7 and 8, and they are hardy to Zone 3. The key to success in the majority of the United States is to provide full light and well-drained soil. Peonies even enjoy the winter’s coldness because it helps their buds grow.
Types of Peony Flowers
You can pick from six different varieties of peony flowers: anemone, single, Japanese, semi-double, double, and bomb. The odors of different plants also differ; some, like “Festiva Maxima” and “Duchesse de Nemours,” have seductive rose-like aromas, while others have a lemony scent or none at all.
Where to Plant Peonies
When planted as a low hedge or along sidewalks, peonies make excellent sentinels. As majestic and dignified as any flowering shrub, the peony’s bushy cluster of attractive glossy green leaves lasts all summer before turning purplish-red or gold in the fall.
Peonies work nicely with irises and roses in mixed borders and blossom alongside columbines, baptisias, and veronicas. Plant pink peonies with blue Nepeta or violets, then surround white peonies with yellow irises and a froth of forget-me-nots.
Peonies are not overly picky, but you should pick your place carefully because they dislike disruption and do not transplant well.
Although they can survive in partial shade, peonies like full sun, and they flower at their best in an area that receives 6 to 8 hours of sunlight per day.
Because of its huge flowers, peonies can become top-heavy in severe winds. Therefore, provide shelter. (If necessary, stakes can be used to hold them up.) Planting too close to trees or bushes will cause peony to compete with them for nutrients, sunlight, and moisture.
Grow peony in rich, wet, humus-rich soil that is deep, fertile, and well-draining. pH in the soil should be neutral.
When to Plant Peonies
As long as they are planted correctly and become established, peony plants require minimal upkeep. However, keep in mind that they do not adapt well to transplanting, so you should consider this when choosing your planting location.
- Plant peony in the fall: in the majority of the United States, in late September or early October, and even later in the fall in Zones 7 and 8. Your planting zone can be found here.
- If you need to move an established plant, the fall is the ideal season because the plant will be dormant.
- About six weeks before the ground freezes, peonies should be planted.
- While planting peonies in the spring is absolutely a possibility, the results aren’t always favorable. They often trail behind plants planted in the fall by roughly a year, according to experts.
How to Plant Peonies
- Peonies are typically offered as divisions of a 3- or 4-year-old plant, bare-root tubers with 3 to 5 eyes (buds).
- Peonies should be placed 3 to 4 feet apart to allow for enough air circulation. The development of disease can be facilitated by stagnant, damp air.
- In a sunny area, dig a generously sized hole that is about 2 feet deep and 2 feet wide. The inclusion of organic matter in the planting hole will improve the soil. Add additional compost to the soil to improve it if it’s sandy or heavy. Add about a cup of bonemeal to the ground. Find out more about soil improvements and getting the soil ready for planting.
- The roots should be positioned in the hole just 2 inches below the soil’s surface, with the root’s eyes facing upward on top of a mound of soil. Avoid planting too deeply! Choose early-blooming species, put them approximately 1 inch deep, and provide some shade in southern states.
- Backfill the hole after that, being careful to prevent soil settlement and a 2-inch root burying. Gently tamp the ground.
- Plant a container-grown peony no deeper than it was when it was in the pot.
- When planting, give everything plenty of water.
How to Care for Peonies
Young peony take time to develop, just like children. In order to establish themselves, blossom, and flourish, they typically require a few years. They eventually leave home on their own, fully grown and adjusted… No, that’s just kids, I suppose.
Peonies benefit from gentle neglect. They don’t require digging and dividing every few years like the majority of perennials do.
- Don’t use any fertilizer. Before planting, till the soil thoroughly while adding compost and a small amount of fertilizer.
- Early summer, after the peonies have flowered and you have deadheaded the blooms, is the ideal time to apply fertilizer (such as bonemeal, compost, or well-rotted manure) to a soil that is deficient in nutrients. Keep fertilizing to a few years at most.
- assist the stems Peonies’ stems, which occasionally are not strong enough to hold their enormous blossoms, are the only part of their structure that may be considered weak. Think of structures that allow the plant to grow through the middle of the support, like three-legged metal peony rings or wire tomato cages.
- Peony blossoms should be deadheaded as soon as they start to fade, cutting to a sturdy leaf so that the stem doesn’t protrude through the foliage. To prevent any infections from overwintering, trim the foliage to the ground in the fall.
- Avoid covering peonies with mulch. For the first winter following planting, you can VERY LOOSELY mulch with pine needles or shredded bark when the winters are bitterly cold. In the spring, get rid of the mulch.
Peonies bloom between late spring and early summer, but by planting a variety of cultivars, you may arrange your garden for a succession of blooms from mid-May to late June. Here are a few options:
- ‘Early Scout’ has red solitary flowers that open incredibly early.
- “Firelight”: very early-blooming, single, pale-pink flowers
- ‘Karl Rosenfield’: double, midseason bloomer with substantial crimson blooms
Where can you find peony in Zone 8?
Late February to early March is when tree peony often bloom. Around April 1st, herbaceous peonies begin to bloom.
Growers have had success with all varieties of peony, including tree, herbaceous, and intersectional varieties. Itoh hybrids are another name for intersection peonies.
All plants have been harmed by the exceptional heat wave in 2012 and the drought in 2011.
One gardener claimed that many of the well-established plants in her gardens did not survive the hardship of the summers of 2011 and 2012. These include certain tree peonies, contemporary rose hybrids, and hydrangeas. Tree peonies that had flourished in the ground for 6-7 years perished as a result of drought-related stress. Despite the drought, this extremely knowledgeable gardener stated that her “Snow Lotus” tree peony has performed exceptionally well. In fact, she claimed that it is the only tree peony that she would without a doubt advise gardeners in her region to grow. She has a specimen that is almost ten years old, 4.5′ tall, and produced 26 flowers the previous year.
In Texas, amid years of drought, the rockii tree peony ‘Snow Lotus’ has proven to be a particularly dependable grower.
It makes sense that ‘Snow Lotus,’ a domesticated variation of the wild species Paeonia rockii, can withstand dryness and stress better than other varieties of tree peonies that have undergone cross-pollination under more hospitable conditions. P. rockii’s natural habitat is in northwest China, particularly in the desert Gansu Province, where there is only an average of 12 inches of rain per year. This amount of precipitation is less than half of what Dallas, Texas, received during the 2011 drought.
This image was captured in May in the countryside near Lanzhou, in the Gansu province of northwest China. The P. rockii species of tree peony is native to this area.
The rockii or Gansu Chinese tree peonies are therefore suggested for growers in hot, arid regions of the country who are interested in growing tree peony.
Herbaceous peonies are extensively grown in this region and present no unique difficulties.
Site selection: It is recommended to plant peonies in warmer regions so that they can get some shade from the intense summer sun. We advise early sun and afternoon shade for all planting zones. If this is not feasible, place peonies close to a sizable shrub so they can receive some shade from the intense sun.
At least two deep waterings per week are recommended in the spring and summer, with any additional drinks needed in between. Particularly for newly planted peonies, this is crucial.
Additional advice: At the beginning of November, remove any lingering tree peony leaves. Cut the foliage of herbaceous peonies to the ground now as well. Make sure the “eyes” or buds are essentially at the surface when planting herbaceous peonies, with only a thin coating of soil or mulch covering them.
In what climate zone do peony thrive?
Now that you are aware of the distinctions between the two primary Peonies, let’s approach your choice based solely on the available information.
Location & Climate: If you reside in the extreme south or north, temperature and humidity may have a significant impact on your choice of peony.
Garden peonies will thrive if you are in a northern region with a shorter, cooler growing season. Garden Peonies are especially popular in Zones 3 through 8, where they may require a little more care.
- A tip for getting them to behave perfectly if you live in the deep south is to select an early-blooming type that will go into flower before the summer heat arrives.
- In the same way, a late-blooming Garden Peony is likely to succeed better in zone 3’s northernmost regions, where temperatures will have warmed up enough for it to flourish during their peak bloom period.
Available Sunlight: Unlike Itohs, which love dappled light and can even take part-sun, Garden Peonies require full sunlight. As a general rule, your garden will be exposed to more sun and humidity the further south you live. You should give your peony more room in hotter, brighter climates so they may receive more air circulation and perhaps a little less sun than usual.
What degree of heat can peony withstand?
While tree peonies and some early-blooming herbaceous and intersectional varieties do well in moderate areas, where they bloom from late April to early June, all peonies prefer lengthy, frigid winter temperatures. Festiva Maxima, a creamy white intersectional with pink undertones, and the rosy “Sarah Bernhardt” are two herbaceous early bloomers. “Bartzella,” a lemony yellow intersectional, will also fall dormant in climates where winter days are not frequently bitterly cold.
The majority of peony require prolonged winter chill, which is defined as periods of time when temperatures are between freezing and no higher than 45 degrees F. Most peony require 480 cool hours or more to achieve a suitable dormancy.
Herbaceous species of the three types of peony require the most hours of darkness. Herbaceous species are more likely to become dormant in mild climates if planted no deeper than 1 inch below the surface of the soil. There has to be considerably deeper planting of intersectional species and trees.
In Zone 8, when can peony be transplanted?
Peonies can be left in the garden unattended for a long time. But on occasion, it’s important to relocate established plants. To improve flowering, move peonies that are sheltered by tall trees or shrubs to a sunny location. The peony may need to be relocated in order to redesign a perennial bed or border. Plants that are large and robust can be dug up and divided for further growth.
The ideal month for transplanting established peonies is September. Cut the peony stems at or just above ground level to start. Next, thoroughly excavate each plant’s perimeter and its base. Keep as much of the root system as you can. Replant the peony right away in a sunny, well-drained area.
Large peony clumps must be divided in a number different ways. Shake the clump carefully to remove any loose soil from the root system after you’ve dug up the plant. Section off the cluster using a big knife. Each division needs to establish a strong root system and at least three to five buds (eyes). Smaller divisions will take longer to mature into beautiful plants.
The optimal conditions for peonies are full light and well-drained soil. Choose an area that receives at least six to eight hours of direct sun each day when choosing a planting site. Avoid standing in the shade next to big trees and plants. Compost, peat moss, or leaf mold used in significant quantities can typically improve poorly drained soils.
When planting a peony, make sure the hole is big enough to fit the plant’s root system comfortably. With the buds one to two inches below the soil’s surface, place the peony plant in the hole. (Peonies frequently don’t bloom successfully if the buds are deeper than two inches.) As you backfill the hole, compact the soil around the plant as you fill it with soil. then thoroughly rinse. Peonies should be spaced three to four feet apart.
Apply a four to six inch layer of mulch over the newly planted peonies in the late fall (mid-November to early December). Pine needles and weed-free straw are great mulching materials. Mulching keeps the soil from repeatedly freezing and thawing in the winter, which could lift the plants out of the ground. Early in the spring, before growth starts, remove the mulch.
Peonies that were transplanted might not bloom well the first spring. However, by the third or fourth year, the number of flowers should increase quickly.
Do peonies reappear each year?
Peonies may not bloom for as long as some other summer flowers, but when they do, they have a beautiful presence that will continue to return for 60 to 70 years without any effort.
Consider these aristocratic plants as a long-term investment for your flower bed ideas even though they are typically more expensive than roses, for example.
It is simple to understand why peonies have been grown in China for thousands of years and are considered the “monarch of flowers.”
Should peony be planted next to your home?
Is it true that ants are required to open peonies, or is this just an urban legend? Does anyone have a firm response to this? There is a lot of debate on the internet.
According to my own observations, you do require the ants to open the bud, at least until a few petals are visible. Ants are drawn to peony whether or not they are required. So I advise setting your peonies outside of the building. You will get an infestation if your plants are too close together. Not that I have any firsthand knowledge or anything…
Peonies aren’t particularly appealing to deer and rabbits, since we’re on the subject of animals. If those pests are a concern for you, plant without worrying about them getting devoured.
