No garden should be without the majestic, long-lasting woody shrubs known as tree peonies. Some types have plants that can produce fragrant flowers up to 10 inches in diameter and grow to heights of 45. Tree peonies are hardy from Zones 4 to 8, do well in the Northeast and Midwest, and flourish in climates with cold winters and hot summers. Tree peonies can be forced into dormancy by gardening in Zone 9: remove all foliage in November, leaving the woody stems, and do not water or fertilise. Hopefully, this will cause the plant to develop blossom buds.
Tree peonies may take three years to develop and begin blooming, so they are not a plant for the impatient gardener. Also keep in mind that it could take several seasons for a new plant’s flowers to bloom to their full potential. Having said that, there is nothing quite like a Tree Peony in full bloom; it is a breathtaking sight.
Before they blossom, Tree Peonies require some time to acclimate; it’s not uncommon for a plant to hold off until its third spring. Additionally, the first spring following planting, Tree Peonies may take longer to emerge from dormancy. Although your plant might appear to be dead while its neighbours are coming to life, it will soon reawaken.
Light/Watering: Flowers need some light protection from the sweltering afternoon sun. In China and Japan, little parasols are used to screen the plants from the sun. Plant tree peonies where they will be shielded from the winter and summer winds that can dry them out. Once established, Tree Peonies are exceptionally drought tolerant. Avoid overwatering plants, and keep them away from automatic irrigation systems. Prior to heavily watering, allow the soil to dry to a pH of 4. The roots will be killed by excessive watering, which is a common cause of failure.
Tree peonies require fertilised soil with a pH that is somewhat above neutral or close to neutral. When planting, add a few handfuls of lime if your soil is acidic. Remove the green plastic ribbon that is wrapped around the stem’s main portion before planting the plant at the depth specified by the ribbon. In order to stimulate the scion to develop its own roots if the ribbon has become dislodged, plant the top of the graft union, which is visible as a bulge on the main stem, approximately 46 below the soil’s surface. In the spring, topdress plants with an inch of aged manure or compost. During the growing season, foliar feeding with fish emulsion is beneficial.
Pests/diseases: On rare cases, you might discover a boring insect-caused hole in the wooden stem. Using a thin wire or by just cutting out the troublesome part, you might be able to kill the larva in the tunnel. Like Herbaceous Peonies, Tree Peonies may contract fungal infections that result in leaf blackening and wilting. As soon as unhealthy foliage is seen, it should be removed. In the fall, make sure to pick up any plant pieces that have fallen. Spray with a fungicide early in the spring and repeat the treatments for a few weeks if fungal diseases start to be an issue. Deadhead flowers regularly and avoid letting dropped petals get stuck in the plant or on the ground.
Companions for Tree Peonies are Hellebores, Alchemilla, Leucojum, Epimedium, and Siberian Irises. Underplant with bulbs that bloom in the spring if your plants have a tendency to be leggy.
Pruning: Unlike their herbaceous siblings, Tree Peonies should never be cut back to the ground. After plants have flowered, remove any broken or damaged stems by pruning. Once your plant has matured and is thriving, you might wish to make a small opening in the centre to promote flowering on the taller stems and improve airflow. When Tree Peonies are grafted into Herbaceous Peony roots, the rootstock will occasionally send up a shoot from the plant’s base. These need to be taken out right away.
Dividing/Transplanting: Tree Peonies do not require division, and it is impossible to do it with numerous plants. When dormant, young plants can be transplanted; when digging the plant, try to keep as much soil around the roots as you can.
End-of-Season Care: After a deadly frost, remove all leaves, including leaf petioles, and dump it elsewhere, not in the compost pile. Mulched new plants should also have burlap or another material wrapped around them to block winter winds in the coldest climates.
Topdress plants with an inch of old manure or compost in the early spring. Keep an eye out for symptoms of a fungus infection and administer treatment as necessary. Remove any shoots that appear from the rootstock.
Mid-Spring: Due to their heavy blossoms, certain types may require assistance. To increase airflow, thin out any foliage that is too densely packed inside the plant.
Avoid overwatering in the late spring. Deadhead blooming promptly, and take out old flowers and petals from the garden.
In the summer, water plants only when the earth has dried to a depth of four inches. Fish emulsion feeding of the foliage is preferred.
Fall: Tree Peonies are woody shrubs; do not cut them back. After the first frost, remove all foliage; do not compost. Mulch newly planted vegetation and vegetation produced in colder climates, and if brisk winter winds are predicted, wrap vegetation in burlap or another windproof material.
Where should a tree peony be planted?
The majority of tree peony are hardy in zones 4–8, although some cultivars are hardy as low as zone 3. They thrive best in regions with hot summers and cold winters for dormancy. Tree peony prefer some dappled to light shade from the sweltering afternoon sun while being typically listed as full sun plants. The lovely blossoms may fade and wither more quickly if there is too much bright sunlight.
They require sufficient drainage and love slightly alkaline soil. Additionally, tree peonies favour a location free from competing tree or shrub roots. With perennial companion plants, they thrive.
Instead of in the sweltering summer, new tree peony plants should be planted in the spring or fall. At initially, they may take up to three years to become established and begin to develop and bloom. Tree peony do not transfer well and may tolerate drought once they are established. A plant can live up to 100 years if it is placed appropriately and is happy with its surroundings.
Gardening for tree peonies is not any more difficult than gardening for herbaceous peonies. However, tree peonies should never be pruned back in the fall, unlike herbaceous peonies. Tree peony should never be trimmed or shaped; only dead, unhealthy, or infected wood should be removed.
They may benefit from a yearly feeding of iron sulphate and bone meal in the spring since they have high iron and phosphate requirements. A general-purpose fertiliser like 5-10-5, which is higher in phosphorus than nitrogen and potassium, should also be applied regularly to tree peony.
The best way to water tree peony is directly at the root zone because they can be vulnerable to fungus illnesses. Borers can also harm them, so be vigilant about looking for evidence of their activity in the wood.
How quickly do tree peonies grow?
Woody perennial shrubs called tree peonies are. After woodland peonies but before herbaceous peonies, they bloom in the early spring. They have enormous dinner-plate-sized flowers on up to 7-foot-tall stems that are supported by their woody structure. Tree peony may tolerate full sun, but they prefer dappled light to grow. After blooming, tree peonies provide the garden structure with their deep green summer foliage that turns bronze and purple in the fall. These deer-resistant plants are native to China and have been grown there for millennia. They do well in zones 4-9. In zone 4 during especially hard winters, some die-back might happen. A tree peony’s annual growth of new woody growth ranges from 1 to 6 inches. They need soil that drains well. a landscape-friendly plant. regal, uncommon, breath-taking blossoms, truly amazing.
What distinguishes peonies from tree peonies?
Tree peony are actually small bushes, not trees, and they bloom in May and June with stunning goblet-shaped flowers. Tree peonies are higher and maintain a constant framework throughout the year, in contrast to herbaceous peonies, which die back every year.
How to grow tree peonies
In the fall, plant tree peonies in wet, well-drained soil in a location that receives some to all of the shade. Except for those that remain quite moist over the winter or are on the acidic side, most soils are good. When buying, plant them somewhat deeper than the soil level in their container.
Cut off any suckers that you notice at the base of your tree peonies because they are growing from the rootstock and will look different from the rest of the plant.
All summer long do tree peonies bloom?
I have long been a collector of tree peony because I adore them. Across from my summer house, I have a tree peony border planted beneath a grove of enormous, shaded maple trees. Many of the specimens came from my Turkey Hill garden, which I transplanted. Some were newly planted last year from Cricket Hill Garden in Thomaston, Connecticut, while others were added more recently. Here on my property in Bedford, New York, all of them are still doing well.
The tree peony season is only seven to ten days long, yet despite this, I adore these enormous, frequently fragrant, white, pink, yellow, red, and burgundy blossoms. Enjoy these images of current blossoming plants.
I adore the tree peonies, Paeonia suffruticosa, that form my border. The full bloom of a tree peony is a tough competitor for most other plants. Although the season frequently fluctuates from year to year, they bloom around late April to early May.
Peonies were introduced to England by the Romans in the year 1200; they are native to Europe and Asia. Peonies have been used medicinally for thousands of years, including treating asthma, reducing labour pain, and treating headaches.
China’s national flower is the peony. Paintings of peonies are frequently found displayed on walls as charms.
The peony is regarded as the modest king of flowers and is a representation of fortitude, bravery, and good fortune in Japan.
Peonies were referred to by the renowned merchant and adventurer Marco Polo as “roses as huge as cabbages.”
Choose a spot for your tree peony that has good drainage, four to six hours of direct light, or partial sun and shade all day. A location with wind protection is also beneficial.
Select a location that can hold a mature plant in mind as most tree peony will grow between four and seven feet tall and between four and five feet broad.
Tree peonies enjoy open, breezy areas because air circulation around the plant protects it from fungi that cause diseases like peony wilt.
A plant may need two to three years to adapt before it begins to blossom profusely, but any gardener would agree that the wait is worthwhile.
More than one hundred flowers may be present on a mature plant, and each bloom may be 10 inches or more in diameter.
Tree peony require soil that is deep, rich, and loose, with a pH of 6.5 to 7.0; they really prefer a little alkaline soil.
Tree peony are drought tolerant plants once they are established. Don’t water until the soil is completely dry since too much water will suffocate the roots.
Although the tree peony’s blossoms are often larger than those of its herbaceous peony relatives, both varieties come in single and double varieties.
All shades of white, pink, magenta, and dark maroon are available in them.
Maroon flowers have less fragrance than pink blooms. They are also resistant to deer, which adds to their allure.
The optimum time to plant tree peony is in the fall since it promotes the growth of new roots and recovery for typical spring growth.
Because they consume a lot of food, tree peonies benefit from a substantial early-autumn top dressing of bone meal or rose fertiliser. The abundance of potash promotes the growth of flowers. In the spring, a small sprinkle of a general fertiliser can be used.
Tree peony set their buds in late summer to early fall, therefore any trimming that is necessary should be done immediately following flowering to preserve the blooms for the following year.
They don’t require much maintenance, but I frequently prune the tree peony by hand and have discovered that pruning to a height of approximately four to five feet produces a lovely eye-level view of blooms.
Large amounts of nectar produced by flower buds draw ants. In actuality, ants aid in the opening of flower buds and offer defence against dangerous insects. Flowers give out a soft, sweet scent that draws wasps and flies that help with pollination.
The peony is a perennial plant that, given the right cultivation circumstances, can live for up to 100 years. I hope to see these most beautiful blossoms for many seasons to come.
Should tree peonies be pruned?
With these easy tips, you can maintain the finest appearance for your adult tree peony:
- Remove any dead wood to get to a healthy bud first.
- Cut a few stems back to fresh buds at soil level, or to within 15 cm of the ground, to improve the shape of your tree peony or reduce its size.
- Leggy stems should be pruned by a third to encourage plants to grow more bushy growth.
- By cutting one or two old stems all the way down to the ground, elderly, neglected plants can be revived. To lessen the damage, spread this out across a number of years.
These pointers should help you maintain your tree peony in top condition so that it can continue to provide you with a stunning spring display for many years to come.

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 odours 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 favourable. 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 fertiliser. Before planting, till the soil thoroughly while adding compost and a small amount of fertiliser.
- Early summer, after the peonies have flowered and you have deadheaded the blooms, is the ideal time to apply fertiliser (such as bonemeal, compost, or well-rotted manure) to a soil that is deficient in nutrients. Keep fertilising 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
