Chinese for “tree peony,” or “mudan,” these long-lived, woody, deciduous shrubs are indigenous to China and may be grown in USDA zones 4-9. The cultivated tree peony, Paeonia suffruticosa, is genetically descended from a number of wild species. The size, color, and scent of tree peony’ mid- to late-spring blossoms are unmatched. A mature tree peony, despite its fairly slow growth, can produce over fifty 8–10″ flowers that bloom for around two weeks. Once grown, tree peonies are reasonably drought tolerant and resistant to deer. Plant on healthy soil with good drainage and 5 to 6 hours of sun. Tree peony do not receive an autumn pruning and instead bloom on “aged wood.” For additional details on tree peony maintenance and their lengthy history as cultivated plants, see our Learn section.

Are tree peonies fragrant?
Peony flowers offer a brilliant burst of color to the environment and are beloved by most gardeners for the beauty of their magnificent petals and their bold foliage that changes colours with the seasons. One of nature’s most beautiful perennials, they are practically careless once established, produce some of the nicest cut flowers, are deer resistant, and survive for years.
Furthermore, Mother Nature has been extraordinarily kind to the Paeonia species, as many of the peonies are also beautifully scented, which adds even another benefit to your enjoyment of cultivating this wonderful garden perennial!
- Peonies have a variety of scents, from pink and sweet to lemony and peppery.
- Some peonies have strong scents that can be enjoyed at a typical viewing distance, while others have milder scents that need to be smelled closer to the flower to be appreciated. These mildly scented peonies might be used better inside, where their scent won’t be overpowering.
- The age of the flower, temperature, and humidity can all have an impact on how the smell changes throughout the day. Early in the morning, when the sun first warms the blossoms, they are frequently at their most fragrant; later, when the day heats up, they may become just moderately fragrant or even completely unnoticeably fragrant as the flower’s volatile essential oils evaporate.
- The majority of single and red peonies lack aroma, with a few outliers, whereas double, white, and pink peonies typically have the strongest fragrance.
Here are some fragrant peonies that are great for cutting and bringing within, as well as being the star of your spring garden.
What distinguishes a peony from a tree peony?
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.
Why don’t my peonies have a scent?
Adrian Higgins, a gardening journalist for the Washington Post, responded to inquiries recently in an online chat. An modified excerpt is below:
Q: My peony have not smelled for the previous two years. They are dated plants that have undergone numerous divisions. That might be the cause.
A: As long as the bud is not hampered by moisture or disease as the bloom develops, there is no evident reason for a previously fragrant peony to change its spots. Many flowers only smell good at specific times of the day.
My two Rosa carolina wild rose bushes are, well, wild. I’ve read that I should leave them alone, but would it hurt if I cut them back a little (or a lot)? Should I wait until late winter to prune them, or may I do it in the summer after they have lost their bloom?
A: Since these plants only bloom once (I believe), they can be severely clipped after blossoming. Put on long sleeves and heavy gloves! And I have indeed become your mother.
A: To prevent weed growth, my landscaper suggested that I spray Preen over my garden beds. Is this harmful to the environment or the other plants? Although I prefer to hand-pull weeds and use a lot of mulch, the weeds are quickly taking over.
Preen is a pre-emergent, meaning it won’t stop those that have already started to grow, but it will stop new growth. They use corn gluten to create an organic version. The drawback is that it would obstruct the growth of biennials and annuals that you wanted to germinate.
A: How should petunias be deadheaded correctly? My mum advises cutting the stem just before it connects to the main stem. I decided it was acceptable to simply remove the deceased flower’s base.
A: To encourage bushiness, either pinch the flower with your finger or clip it back more.

The duration of tree peony blooms
Gardeners simply can’t get enough of peonies’ enormous, sultry flowers, which are a mainstay of perennial borders. It’s understandable why we would wish to prolong the blooming season of these exquisite charmers if they also had a nice, seductive aroma.
Peonies are incredibly resilient to pests, have a long lifespan, and need little maintenance to produce vibrant flowers. The only issue peony farmers have is that they wish they had more time to enjoy those magnificent flowers. Let’s look at several ways to prolong peony blooming in your garden.
Peonies can bloom for over a century, almost by magic. Every plant will produce several flowers, and each bloom lasts for about 7 to 10 days. Planting kinds of peonies that bloom at various times during the about 6-week period of proficient flowering is the easy trick to extending peony blooming in your garden. Since different varieties bloom at various periods of the year, we have neatly categorized them as early, early-mid, mid, and late season. So now that you have mastered prolonging the peony blooming season, let’s take a closer look at each type.
How big 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.
What distinguishes an Itoh peony from a tree peony?
The Itoh hybrid peony are the newcomers to the garden. Peonies from the Itoh region are a hybrid of tree and herbaceous varieties. It took decades for these hybrid peony, which were first created by Japanese horticulturist Toichi Itoh in the 1960s, to be made widely accessible to the general public. Due to their hybridization of herbaceous and tree peony, these flowers are also known as intersectional peonies. Due to their fantastic features, Itoh peonies are more common in nurseries and online merchants.
Itoh peonies have many characteristics with herbaceous peonies, such as big, spectacular, and frequently fragrant blossoms. The leaves and stems of these Itoh hybrid peony die back to the ground over the winter months, just like herbaceous peonies do. Itoh peonies get qualities from their other parent, the tree peony, such as their robust stems, which keep flowers from drooping after a lot of rain. Itoh hybrid peonies also bloom later in the growing season and often begin blooming when the herbaceous peonies are wrapping up their season-long blooming. Itoh hybrid peonies also take a little longer to bloom than herbaceous peonies do. Itoh peonies will occupy around the same amount of space in your garden as herbaceous peonies due to their similar spread and height of 2-3′. The Itoh hybrid peonies have gorgeous, dimensional color ranges that I have noticed. Many varieties, including Hillary Itoh Hybrid Peony, feature hues of coral, peach, pink, and orange. Purple Heaven Large solitary flowers measuring 6 across are present on Itoh hybrid peony. Cora Louise The single, beautiful, pale pink blooms on the Itoh Hybrid Peony have a brilliant pink center and are fragrant. It is understandable why Itoh peonies are sweeping the gardening world by storm with their wide variety of hues and later, longer bloom time.
