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.

What distinguishes a tree peony from a bush peony?
In USDA hardiness zones 5 through 9, the little shrub known as tree peonies (Paeonia suffruticosa) can reach heights of up to 10 feet. They grow considerably more slowly than garden peonies and prefer sites with partial sunlight. Unlike garden peonies, which die back to the ground in the winter, tree peonies do not require as much water or fertilizer. When they awaken in the spring, they will carry on growing on their wooden stems.
How can I tell a tree peony apart?
Do you have a tree peony that also blooms as a herbaceous peony, or a chimera peony, in your garden? Actually, the herbaceous peony understock, or rootstock, of the tree peony has emerged in this situation, which is not some uncommon mutation.
A “Souvenir du Maxime Cornu” tree peony that was grafted with herbaceous understock has sprouted and is in bloom in our garden. In this instance, the tree peony and the herbaceous understock are in full bloom at the same time.
Grafting is the most frequent method of producing new tree peony. In a nutshell, this is a technique for multiplying peonies in which a cutting from a tree peony is fused to the root of a herbaceous peony. In its early years of development, this serves as the tree peony’s “battery.” Last year, I described this procedure in detail.
Unhealed tree peony graft with a rubber band holding the tree peony scion to the herbaceous peony understock.
The roots of this tree peony are starting to spread on their own. The bulbous part of the root is the understock of the herbaceous plant. To ensure that the tree peony continues to spew its own roots, this plant must be planted quite deeply if it is to grow successfully.
A tree peony cannot develop its own roots if it is planted too shallowly. Both sprouted understock and general plant weakness may result from this.
It was improper to place this tree peony so close to the graft union. The tree peony won’t be able to develop its own roots in this situation. More earth should be piled around the plant in this situation.
If a tree peony has sprung herbaceous peony understock growing on it, the herbaceous peony will eventually overtake the tree peony and kill it out if the situation is not dealt to. To prevent this, the herbaceous rootstock must either be removed from the tree peony at the root in the fall or below the soil line in the spring. The plant that has to be preserved is the tree peony since it is more rare and valuable. Cutting back the herbaceous peony foliage BELOW the soil line and then piling up six inches of soil around the tree peony’s base is the simplest procedure. This can be done at any time and will prevent the herbaceous peony from sprouting again while promoting the development of the tree peony’s own roots.
Wait until the fall to plant the herbaceous peony if you really wish to save it and move it to another area of your garden. When it comes time to dig and divide peonies in a few months, I will write a follow-up piece that will show how to divide a tree peony’s herbaceous understock.
We talked about how to recognize the herbaceous peony understock emerging on a grafted tree peony a few months ago. This frequently happens when grafted tree peonies are planted too deeply. It’s time to dig up and remove undesired herbaceous understock and replant the tree peony now that the time for transplanting peonies has come. This must be done because, if not stopped, the herbaceous peony would eventually suffocate and suffocate the tree peony. You can replant this and let it grow out if you enjoy how the herbaceous understock blooms.
If you have a tree-herbaceous hybrid peony, now is the time to dig it up, remove the undesired herbaceous peony suckers, and replant the tree peony deeply enough for it to develop its own roots and survive for many more years.
The leaves of herbaceous peonies can easily be distinguished from those of tree peonies. While the leaves of herbaceous peonies are elliptical and pointed, those of tree peonies are dissected and three-pronged.
You can always look at the stems to determine whether the leaves are different. Herbaceous plants are green, while tree peonies are woody.
Digging up the peony requires first removing the leaves. In order to prevent them from spreading dangerous fungus throughout the garden, dispose of these in a hot compost pile or outside.
Digging up a huge peony cautiously is the best approach. Start by excavating around the plant’s perimeter, about 18 away from the drip line. Finally, gently pry the plant out of the ground after removing some of the soil from around its roots.
There are very few tree peony roots in this plant; most of its roots are herbaceous peony roots. The little white buds that have developed at the base of the herbaceous stems this year are the herbaceous peony’s “eyes.”
The tree peony would die or become weaker if all the herbaceous roots were removed right once because this plant has so few tree peony roots. Trim these pink or white buds to get rid of the herbaceous peony ‘eyes’ as soon as possible. The tree peony should be deeply replanted so that it can develop its own roots over the ensuing few years. Where the herbaceous peony roots first appear, or about 4 above the graft union, is where to plant the tree peony. Use this chance to add the right soil amendments for the tree peony. Shovel one or two shovelfuls of compost into the planting hole. If your soil is acidic, mix in a cup of limestone dust while you backfill. As you fill the hole, add a couple additional shovelfuls of compost and a cup of azomite to provide the plant with extra minerals.
Water the soil/compost mixture in as you back fill to help it settle nicely around the roots. If you still have some compost on hand, top dress the soil by tamping it down and adding a shovel’s worth. For their first winter in the ground, newly planted or replanted peonies should have mulch used to assist prevent the soil surrounding the roots from freezing and thawing abruptly, raising the roots above ground.
In our USDA zone 6, tree peony can be transplanted at any time between now and early November. Making sure that the roots do not dry out while they are out of the ground is crucial. Don’t forget to plant in an area that is sunny, well-drained, has rich soil, and has a pH of at least 6.5.
How can I tell if my peony is herbaceous?
In peonies, true red might be difficult to find. Frequently, when you believe you have located it, the plant is actually magenta. Similar to coral peonies, there is a superb group of herbaceous hybrids that provide exceptional true red cultivars. These flowers typically have simpler forms. They either have the contrasting bright yellow centers or the anemone flower shape’s spiky inner petals. These cultivars have light flowers on strong stems and stand straight in the garden without the need for staking. They are the ideal plants to give the garden some color.
These varieties, like coral peonies, have a dramatic appearance when planted in lots of them. This can be a collection of just one cultivar or a variety of cultivars that are all in this true red color range.
We advise planting a row of classic white herbaceous peonies, such Festiva maxima, in the back and a row of a real red herbaceous peony in the front for a spectacular appearance. This combination will definitely dazzle.
Do tree peonies require pruning?
The ideal time to prune a mature tree peony is in the early spring. In the zone 6 area below, the best time to do this is after the buds have started to swell but before new growth has started. Pruning can be done in the fall or winter in zones 7 and above when there is little risk of winter damage.
Once the buds have started to swell a bit, prune tree peony. In this manner, it is clear whether a bud is alive or not. This often happens in late March in New England.
A pair of bypass pruners and a small pruning saw are suggested tools. Ensure that they are precise!
Cut off the branch at the nearest live bud when pruning a branch that still contains some healthy buds. Just above the first living bud, the incision should be made with an angle that slopes away from the bud. This makes it easier for water to flow off and promotes faster healing.
shoddy pruning cut The dead wood above the bud is sticking out too far. This does not encourage effective recovery.
Examine the plant’s base after you’ve cut back the upper branches. Spindly inner growth frequently passes away, and this dead wood needs to be removed.
After all the dead wood has been taken out, check the plant for any small, spindly growth. These incredibly tiny side branches should be cut off if the plant is healthy and growing nicely. They are often located within the plant. They won’t grow flowers and only obstruct airflow.
Finally, eliminate all pruning from the garden since they can contain fungus spores.
How big can you grow tree peonies?
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.
