These perennial plants form clusters that are roughly 2 to 4 feet height and the same width. By the time they reach maturity, they will require support from twine-tied stakes, deconstructed tomato cages, or metal rings on legs. Flowers come in a variety of hues, including white, cream, pink, and red. The reds could be bordering on chocolate brown in terms of depth. Blossoms come in a variety of shapes, including single, semidouble, double, and Japanese varieties with a single row of petals encircling a substantial core mass.
Blooms can range in size from 2 inches to 10 inches across, depending on the variety. In USDA plant hardiness zones 3 to 8, herbaceous peonies thrive in direct sunlight. Early summer and late spring are the peak blooming seasons. Not all types have scents, however the pink “Sarah Bernhardt” and white “Festiva Maxima” have an aroma evocative of vintage roses.
How tall are the peony flowers?
- Keep plants neat by deadheading and prune as needed (herbaceous only).
- When peonies become congested and produce fewer blooms, divide the plants.
- When the blossoms feel like soft marshmallows, cut the stems for bouquets. Water should contain Miracle-Gro for Fresh Cut Flowers.
When the peonies blossom, you can finally start to feel the arrival of summer. Around Memorial Day, when spring bulb flowers are starting to fade and summer blooms are beginning to emerge, these stunning perennials bloom profusely. Peonies are resistant to deer and rabbits, which is useful for gardeners who frequently experience issues with animals eating their plants. Peonies are frequently seen blooming despite years of neglect if you drive through old cemeteries or abandoned farmsteads. That is because to how simple peony are to grow!
How to Choose Peonies
Peonies come in four different varieties. They are forest peonies, tree peonies, herbaceous peonies, and intersectional peonies, in the order of blooming time. Herbaceous peonies, which thrive in zones 3–7, and tree peonies, which flourish in zones 3–9, are the two most popular varieties. Herbaceous plants often reach heights of two to three feet and spreads of two to four feet. With some types reaching heights of 7 feet, tree peony are more closely related to tiny shrubs. The type of peony you plant will depend on where you live and the style you’re going for because all peonies require similar maintenance. The focus of this paper will be on tree and herbaceous peony.
When to Plant Peonies
Fall is the ideal season to plant peonies. This is often when peonies purchased from a catalog will be delivered. It’s okay to plant peonies when you see them flowering and for sale in containers in the spring.
Where to Plant Peonies
Peonies require at least 6 to 8 hours of sunlight every day, though in zones 8 and 9, some shade from the sweltering afternoon sun is beneficial. Additionally, picking a location with sufficient air circulation is crucial to avoiding fungal illnesses.
How to Plant Peonies
In somewhat damp, well-drained soil, peonies thrive. Dig a hole, take the plant from the pot, and plant container-grown herbaceous peonies (the kind you buy in pots) so that the top of the root ball is level with the earth (any deeper and the peonies will not bloom). Fill up the area surrounding the plant by combining the discarded soil with an equal amount of Miracle-Gro Garden Soil for Flowers.
Before planting bare root herbaceous peonies, give them a brief dip in a basin of water to rehydrate them. Create a planting hole that is big enough to fit the roots, mix the soil as previously mentioned, and place a mound of the blended soil in the middle of the planting hole. Place the roots atop the mound and let them fan out and descend. Using the remaining blended soil, fill in the remaining portion of the hole, making sure that the “No more than 1 to 2 inches of soil should be present around the plant’s eyes (or growth buds) in order for it to bloom.
Deeper planting is required for tree peony. Unless they are grafted, peonies should be planted in the same soil combination as above, 2 to 4 inches deep at the crown (where the roots meet the stem). Check the label to see if the plant has been grafted, and then plant it such that the “The plant’s graft union, where the grafted top and rootstock are united, is located 4 to 6 inches below the soil line.
How to Stake Peonies
Peony stems are prone to toppling over after it rains, and the blossoms can become big and heavy. For herbaceous peonies, the best approach is to cover each plant in a peony cage in the spring, before the leaves begin to sprout (picture metal supports with rings for the flowers to grow up through). This is far more effective than attempting to hold each flower stalk separately, and it also looks nicer than wrapping the entire plant in string and cinching it in like a belt.
One stake can be used to stake tree peonies. Place the stake next to the stem in the ground, and then use a piece of twine to loosely secure the plant to the stake.
How to Water Peonies
When planting, give everything plenty of water. When the spring foliage begins to emerge and the flower buds start to show, give the plants another drink. Although peonies do not have a thirst, they will benefit from watering during dry spells for a year following the first planting.
How to Feed Peonies
Your peony will benefit from a powerful combination of care that includes excellent soil and the ideal plant food. Give peonies the nutrition they require by feeding them Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food in addition to the soil improvements indicated above for stunning color and more flowers than unfed plants. Peonies should be fed twice a year: the first time, right after they emerge in the spring (when the new shoots are 2 to 3 inches tall but before the flower buds are pea-sized), and the second time, in the middle of the growing season (about three months after the first feeding), to help them develop sturdy roots before the arrival of winter. Make sure you adhere to label instructions.
How to Help Prevent Problems with Peonies
Although mostly fuss-free, peonies occasionally experience fungal issues. Browning and failure to open flower buds are symptoms of botrytis. Brown patches on leaves are a symptom of some fungus illnesses. Infected blooms and leaves should be simply pruned off and disposed of (do not compost) in order to control these problems. Additionally, keep the plants neat, remove old foliage at the end of the season, and deadhead spent blooms. Peony blooms occasionally draw ants, but they won’t hurt the plants, so you can ignore them. (Contrary to popular belief, peonies do not require ants to blossom.)
How to Prune Peonies
Cut back each flower stalk on herbaceous peonies once all of the blooms have faded to just above a leaf, low enough so that the stem doesn’t protrude above the rest of the leaves. Unruly tree peony can be trimmed either in the spring or the fall (right before plants go dormant). However, any stems you trim back in the fall will not blossom the following spring (as you will be cutting off the flower buds). After blossoming in the spring, you can prune. Anytime you choose to prune, be careful not to take more than one-third of the plant with you.
How to Divide Peonies
It is ideal to leave tree peony alone (undivided) so they can flourish for many generations in the garden. If the clumps have become too large or the flowering has slowed, herbaceous peonies can be divided. Herbaceous peonies can be divided by digging up the entire clump and rinsing it off to reveal the plant’s numerous roots and eyes (or buds). Leave as least one large root and three to four eyes per clump after cutting the plant apart with clean, sharp pruners. Replant, adhering to the bare root peony planting directions above. The plants might or might not flower the first year after dividing, so keep that in mind.
How to Cut Peonies for Bouquets
Timing is crucial. Buds should feel roughly as firm as a soft marshmallow when squeezed, which is known as the “soft marshmallow stage.” Examining the bud’s coloration is another method for determining when to cut. The majority of the bud’s exterior should remain green, but you should be able to make out approximately half an inch of the flower’s vibrant petals. Although cutting the flowers at this point lessens the possibility of bringing ants inside with them, it is still advisable to inspect the flowers before bringing them inside. Plants should open up when stems are placed in a vase of water. For longer-lasting blooms, change the water every few days and apply Miracle-Gro for Fresh Cut Flowers (vs. water only).

Do peony propagate by themselves?
No, peony won’t naturally grow more plants or spread out. One day you may realize that your peonies have grown rather large and have spread out quite a distance.
If you want to grow more peony plants in this situation, dividing them is your best option. This is the finest approach to propagate herbaceous peonies and a way that you may aid in it.
Peonies can’t actually be encouraged to grow or anything like that. Simply put, it’s better to hold off on taking any action until the peony plant has grown larger.
Dividing peony plants is the only way to produce more of them. Although this method isn’t inherently difficult, you’ll want to become familiar with it so that you can carry it out correctly.
To get more peony plants, read on to find out how to divide existing ones. This will enable you to plant peonies in several garden locations if you so want.
When do peonies bloom?
In the majority of places, flowers bloom in April, May, or June. Around Mother’s Day, tree peonies should begin to bloom, then herbaceous kinds around Memorial Day, and finally intersectionals. Include all three varieties in your garden to get up to seven weeks of flowers.
Pests and diseases:
For peony plants, Japanese beetles can be an issue. They are also vulnerable to powdery mildew and botrytis blight. This can be avoided with good air circulation around your plants. The Missouri Botanical Garden’s guide to peony problems has more information on potential problems.
Do peony grow in size each year?
For generations, peonies have been a garden favorite. In fact, some of the provided types date back to the middle of the 19th century and are still in demand as garden or cut flowers today!
Herbaceous peonies are quite simple to grow as garden plants because they all die back in the fall and come back in the early spring each year. Peony plants dislike being moved once they are established. They can remain in the same place for more than 25 years! All they need is a sunny to partly sunny location with little to no prolonged standing water.
Peony plants can be planted in the early spring or the fall. We’ll send you a peony with at least three to five eyes while it’s bare root (grow points). If compost is available, plant the root in the pre-dug hole. Soil should be applied to the entire plant with the eyes (growth points) receiving no more than 2″ of soil coverage.
Don’t be disheartened if the peony only has one or two flowering stems the first year; this is typical. For the first two years, we advise against cutting the stems as this promotes the expansion of the underground root. You should expect 5-7 blossoms in the second year. Up to the sixth year, when certain kinds may reach up to 25–30 stems per plant, it should increase yearly.
In order for peonies to emerge from dormancy and blossom the next season, they require a cold (winter) time. As a result, they are grown in the southern states with very varied results (USDA zone 9B and higher). While dormant, they are extremely cold tolerant. Even in Fairbanks, Alaska, in the far north, they are successfully grown.
Diseases:
Despite the fact that peonies are relatively hardy in most areas, several (fungal) illnesses can harm them.
– Botrytis (grey mold): This can be a problem in more humid climates. Typically, just the freshly formed flower buds will be affected, not the entire plant. The fungus will brownize the buds, and they can miscarry. In extreme circumstances, it can sometimes harm the stem’s base, causing the stem to collapse there.
– Verticillium: This vascular disease causes the stem to wilt and die back by destroying the vascular cells at the base of the stem.
– Cladosporium (measles): Only the leaves are impacted; measles-like brown spots will form overnight (red varieties seem more susceptible than others). The plant will flower regardless of the measles.
Ice/frozen damage:
This only occurs when there is a heavy frost (28 or below) just as the flower buds are beginning to form. The young bud will develop poorly due to the frost and turn brown or black.
Early in October, we start sending out fall packages using U.S. Priority Mail (unless another method is requested). Spring shipments start in March (or whenever outdoor planting is appropriate in your location), and we continue shipping until May 10. (Crocosmias only sail in the spring.)
