Perennial peonies called herbaceous peonies fade back to the ground every year. The plant stems push up in the spring while the roots remain dormant beneath the dirt. Woody, deciduous shrub peonies are called tree peony. They shed their foliage in the fall, but unlike herbaceous peony, their woody branches do not die back to the ground. Itoh peonies are a hybrid cross between herbaceous and tree peonies; while they do die down to the ground in the fall like herbaceous peonies, they exhibit tree peony-like growth and flowering traits.
Before they became beloved ornamentals, tree peony, which are native to China, were prized as a therapeutic plant. A tree peony can reach a height and width of up to five feet (1.5 meters) in around ten years and is a larger, woodier relative of the ordinary herbaceous peony. They are widely coveted for their huge, prodigious blooms, which can reach a diameter of up to 10 inches (25+ cm).
These blooms occur in single or double shapes and bloom from late spring to early summer. They are great cut flowers. Tree peony do not produce the sweet honeydew sap that herbaceous peonies do, which is what draws ants to their flower buds.
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.
How tall can a tree peony grow?
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 fertilize. 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 neighbors 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 fertilized 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 center 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?
Autumn is the ideal time to grow tree peony, but planting in winter or early spring is also acceptable. Avoid planting in the summer and late spring since the hot, dry weather will make it difficult for plants to establish.
Where to plant
- Place your plant in a sunny or gently shaded area.
- Although tree peony are fairly resilient, avoid late frost pockets because they can harm the leaves and bloom buds.
- To avoid wind damage to flowers and foliage, choose a sheltered area.
- Although they will tolerate slightly acidic or slightly alkaline soils, tree peonies prefer neutral, humus-rich, well-drained soils. Most soils can be sufficiently improved by adding organic matter, such as garden compost or well-rotted manure, but those that are too acidic or alkaline may continue to be unsuitable.
What distinguishes a peony tree from a peony bush?
Because of their woody stalks, tree peonies get their name. The woody stems of tree peony remain intact above the ground even after the leaves fall off of them in the fall. Compared to the bush peony, they typically bloom earlier and with larger flowers. They often grow gradually.
What is the lifespan of a tree peony?
Inquiries concerning tree peony maintenance in UK gardens are frequent.
What makes it the best? When should tree peonies be planted, and how should they be cared for? Below, we share our wisdom and expertise on how to take care of these magnificent plants.
The UK Tree Peony Care
Date of Planting The best time to plant new trees and shrubs in your yard is in the fall. It is simple to dig because the dirt is damp. Additionally, it is warm below the surface, which will provide the greatest possible start for your seedlings. Autumn weather, which is typically wetter and gradually turns colder than other seasons, is best for plants entering into dormancy for the winter.
If plants are planted in the autumn, they will have built a root system by the following spring and will be ready for the more challenging variable hot, cold, and dry weather conditions in early summer. The seasons will soon change, the days will get shorter, pumpkins will be available in stores, and your garden will experience a period of transition.
A common illustration of a plant that grows best in the fall is Tree Peonies. Before the ground freezes solid, usually in late December or early January, plants planted in the autumn gradually grow and settle their roots.
The Tree Peony, also known as Moutan, is a deciduous shrub that originated in China and is not, despite its name, a tree. The Tree Peony is a bigger variety that keeps its exquisite wooden stem or bark throughout the winter, in contrast to the more typical herbaceous peony that dies back in the winter.
Despite having a delicate appearance, Tree Peonies are remarkably tough and bloom for 50 to 80 years. These powerful plants have a remarkable past; they were initially cultivated in China 2,000 years ago and have survived tremendous climate variations.
Tree peonies are prized for their exquisite flowers, and for the finest blooms, they should be planted in full light.

The Tree Peony Attitude
Get your tree peony settled and acclimated before the winter frosts and cold because they are notorious for not wanting to be moved about much. Planting in the fall allows the Tree Peony ample time to grow roots before the ground freezes, which is important because Tree Peonies acquire their nutrients from the roots. This will assist in promoting springtime development. Although tree peony are robust, long-living plants with stunning spring blooms, they grow slowly until they are well-established. Tree peonies can thrive in either direct sunlight or light shade. Give your tree peony plenty of room to grow, don’t place it too close to other plants, and don’t move it once you’ve planted it. Tree peonies can grow up to 2 meters in length and keep their stems through the winter. However, after planting it, you must give it some time to grow.
Location, place, place
In a protected area with good drainage and full sun to moderate shade, tree peonies thrive. The soil must be loose and deep. Mulching the soil after planting is advised to maintain moisture levels and stop soil from drying up.
We grow Tree Peonies in our own yard beneath Japanese Acers in lush, healthy soil. Give the Tree Peony some room so that air may flow around it without being overly exposed and subjecting it to harsh prevailing winds.
Vanity and grooming
Pruning is not very necessary for Tree Peonies. If seeds are wanted, cut back just above the new growth in the summer or the fall to remove flowering shoots. After the leaves have fallen in the autumn, cutting old stems off at the base will promote bushier growth. To promote new flowers, feed the peony in early autumn and once more in late spring.
You are sure to find the ideal color complement for your landscape, from the double-flowering, two-tone Dao Jin Tree Peony to the brilliant yellow Tree Peony Hai Huang.
Are tree peonies leafless in the winter?
These primarily spherical shrubs are broader than they are tall, and they have attractive leaves that highlight the lovely flowers. P. delavayi has a vase-like form and is erect. In the winter, tree peonies lose their leaves.
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.
What flora thrives beneath peonies?
There are numerous peony design and planting alternatives. Additionally, we’ve compiled a list of peony and plant combos that can both work and look fantastic. While there are various floral combinations that can be used with peonies, that is not the only one. There are actually tons of wonderful plant options to match with peonies! Consider growing some of these alongside your peonies:
bushes that grow slowly Ideas for evergreen shrubs to pair with peonies:
Peonies go well with miniature rhodies, evergreen azaleas, and evergreen viburnums. Just make sure to correctly plant each one.
A herbaceous peony is likely to grow shorter than a small evergreen shrub. If you want the evergreen to shine through the winter while the herbaceous peonies take center stage from spring through October, place the shrubs behind them. This is effective because you’ll probably mow this type of peony down for the winter. And once the peonies have awakened from the winter dormancy, several evergreens make a lovely backdrop.
Site the shrub in front of a tall tree peony because it will likely grow much taller than a little evergreen bush. In this manner, the tree peony and the little evergreen will both shine out throughout the year. Alternately, choose a larger evergreen bush to place behind your tree peony. When the peony is leafed out and in bloom, this might serve as a backdrop. Additionally, even when the peony is dormant, the evergreen ought to be evident.
Heavy, floppy peony flowers can also be supported by strong shrubs like these. especially when the spring rains weigh them down. To completely realize this support plant, though, you might need to surround peonies with a few little shrubs.
Also keep in mind that plants like these have a blooming season. Make sure the shrub blooms at a different time from the peony if their bloom colors don’t match precisely.
Evergreen Grasses and plants that resemble grass that go well with peonies:
To complement your peonies, grassy plants like Carex ‘Cappuccino’ can offer year-round interest and a fluffy texture. They also don’t spread very quickly. Evergreen grasses look great when planted next to a peony. However, they won’t be able to support any droopy peony blossoms very well.
ferns that thrive next to peony
Deer ferns that are smaller and evergreen look lovely put behind flowers. While your peonies are dormant, evergreen sword ferns and shield ferns provide interest to your landscape. Your regenerating peonies and evergreen ferns will both sprout new growth in the spring. In addition, ferns complement your tree and herbaceous peonies well when they are in bloom.
Planting groundcovers beside peonies:
Care should be taken when choosing these. Under peonies, creeping Jenny and other groundcovers with vivid colors look fantastic. But be ready to thoroughly and painstakingly winnow away unwanted groundcover roots a few times every year.
Along with peony, cultivate these perennials:
Come back. Combining herbaceous plants with peonies is a lot of fun. Consider choosing perennials that bloom far in front of peonies, such as evergreen hellebores. Alternatively, combine peonies with summer-blooming perennials. When combined with penstemons and agastaches in flower in the summer, peony summer and fall leaves creates a stunning backdrop.
Alternatively, put your peonies’ backs to taller summer perennials. When designed in this fashion, peonies stand in front of tall summer bloomers like marshmallow, hollyhock, or sunflowers like a lovely evergreen shrub.
