Asia, Europe, and western North America are the native habitats of peonies. The peony was once regarded as the national flower of China (it is now officially the plum blossom). In the seventh century BCE, Tang Dynasty citizens in China started cultivating peonies in the royal courts. Early in the 11th century, Japan became a popular destination for them, and in the 18th century, France and England followed. Peonies started becoming increasingly well-liked in the United States in the late 1800s and early 1900s. In fact, the peony replaced the zinnia as Indiana’s official state flower in 1957.
Do peony grow naturally in the US?
North America has two native species of peonies. California peony (P. californica) is only found in the Pacific coastal mountains of California and Mexico, while Brown’s, or western, peony (P. browni) can be found from California to Montana.

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
Do peony grow in Japan?
No native tree peony species exist in Japan. According to historians, the tree peonies, or botan in Japanese, first appeared in Japan in the eighth century CE. It is generally agreed by historians that Buddhist monks—whether Chinese or Japanese—were in charge of delivering tree peonies to Japan. In this setting, tree peonies were viewed as significant medicinal plants rather than beautiful garden plants. The massive transfer of goods and concepts from China to Japan included tree peonies.
Some sources attribute the original introduction of tree peony to Japan to the great Buddhist scholar and monk Kb-Daishi.
Tree peony were cultivated as attractive plants in temple and court gardens throughout the following few hundred years, but it wasn’t until the Edo era (1603 to 1868) that their cultivation spread widely. The introduction of grafting as the primary method of multiplication during this time is primarily to blame for the rapid expansion of tree peony farming. Tokyo, Kyoto, as well as the western coastal prefectures of Niigata and Shimane, were the primary centers of cultivation and propagation.
Hyakken’s peonies
Utagawa Shigenobu’s 1866 woodblock print shows tree peonies in a well-known public garden in Tokyo.
Similar to China, tree peonies have deep cultural value in Japan. Tree peonies are a symbol of good fortune and a righteous and noble attitude in Japanese poetry and visual art.
Japanese tree peonies first appeared in western European botanical gardens in the middle of the 19th century. By the 1890s, a number of sizable nurseries with headquarters in Japan were shipping a significant amount of tree peony to both Europe and the US.
The Yokohama Nursery was renowned for its extensive collection of lilies, irises, and tree peonies. From the early 1900s to the eve of World War 2, this nursery sent goods to the United States.
A detail from a 1920s Yokohama Nursery catalog with gorgeous printing. The varieties displayed are, in order, “Peak of Mt. Fuji, also known as Fuji-no-mime, and Kasane Lion, also known as Kasane-jishi.
A side note: For those who think tree peonies are pricey, take into account that a rare book trader will charge you $5,500 for a vintage Yokohama nursery brochure. By comparison, the real Japanese tree peony on our website, which start at $79, are inexpensive!
There has been a lot of misunderstanding about the proper identification of Japanese tree peony among nursery experts and collectors since they were first brought to the United States more than a century ago. This annoyance was expressed by the grower John C. Wister in his 1962 book, The Peonies:
“Our difficulties [in correctly classifying Japanese tree peony cultivars] have been caused by some Japanese nurseryman’s negligence or dishonesty. From 1910 to 1925, the main exporters would provide a collection of fifty types under fifty different labels, and all but two or three plants would turn out to be identical. The very same company would provide fifty plants of a unique white kind, and the blooms would open in shades of pink, crimson, and purple.
Since then, unfortunately, little has changed; imported Japanese tree peony continue to frequently have incorrect labels. Whether they lived up to their reputation or not, Japanese tree peonies played a significant role in the hybridization of tree peonies by breeders like Prof. Arthur Saunders and Nassos Daphnis. To develop the stunning yellow and apricot tree peonies like High Noon and Marchioness, these brilliant hybridizers mixed Japanese tree peonies with the species tree peony P. lutea.

Japanese tree peonies frequently exhibit a number of morphological characteristics in both their flower appearance and their development habits. This homogeneity is likely a product of both the Japanese tree peonies’ relatively small genetic ancestry and the producers’ aesthetic choices. Japanese tree peonies commonly have huge blooms, 8–12 in diameter, upward-facing, open semi-double flower shapes, and intensely vivid colors, yet they are frequently less fragrant than Chinese tree peonies. When mature, most shrubs are 4 tall and wide. Compared to its Chinese counterparts, Japanese tree peonies are more erect and less bushy. Many of the highly divided leaves have a bluish green hue.
This plant serves as a good example of how Japanese tree peony tend to grow straight rather than bushy.
The majority of Japanese tree peony are semi-double, however there are some significant outliers to this rule. A few types are considered fine doubles, while a large group of semi-double blossoms are referred to as jishi or lion shape. There blooms are believed to resemble a lion’s mane, which is disheveled and tangled.

The Kan Botanor “Winter Blooming” tree peonies are a fascinating subgroup of Japanese tree peonies. Depending on the variety, this type of tree peony blooms in the spring and then reblooms from November to January. The plant only produces a few leaves and much tiny flowers in the winter. It is thought that these unusual varieties date back to the 1700s.
In Japan, straw mats are used to preserve tree peonies that bloom in the winter. At this picture, a tree peony in a park in Tokyo is flowering in December.
It appears that Winter Blooming Tree Peonies were created to thrive in particular temperatures in Japan. We are unaware of any American growers who have been successful in cultivating Kan Botan.
