For the Northwest garden, Swansons provides a variety of Peony types. Peonies need full sunlight, healthy soil that drains well, and regular feeding. Your peony will bring years of beauty and enjoyment with just a little maintenance and appropriate placement.
Planting instructions
The optimum time to plant peonies is in the fall, any time between late September and early December. When purchasing a potted plant in the spring or summer, it is better to wait until fall to transplant the plant. To ensure good drainage, you can temporarily bury the entire pot where it will be planted, covering the soil beneath it with a few inches of gravel.
Make a deep hole that is at least 18″ wide and 24″ long in the fall. Rich, humus-rich soil as well as a lot of compost, composted manure, or peat moss should be used to fill the hole’s bottom. Add 1-2 cups of organic all-purpose fertilizer. This combination and water should be well-tamped. Remove the plant from its pot with care, being sure to untangle any circling or tangled roots. Place it there and backfill the hole with the same soil mixture as you go. When planting is finished, make sure the top of the plant’s bud “eyes” is no lower than 2 inches below the top soil level, taking into consideration any additional mulch layer you’ll add. The final step is to add water to the well.
Care for established plants
Top dress with an all-purpose organic fertilizer 6″–12″ from the plant’s crown the following spring after planting.
Once grown, peonies are reasonably drought tolerant. To promote adequate bud growth, however, care should be made to water during the spring and late summer active growth periods.
Peonies are solely susceptible to botrytis. It can be identified by its withered flower buds and drooping, scorched-looking foliage. Remove any evidence of unhealthy tissue from the plant, wiping your pruners with a solution of rubbing alcohol between each cut. Diseased material should not be composted. Apply a copper-based fungicide to the plant to help manage the illness.
Cut the browning foliage to the ground after your peony’s spectacular fall color display and mulch with a few inches of compost. While you wait for a plant that will be even more gorgeous next season, sit back and unwind.

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

Peonies: do they grow in Washington?
SEATTLE
One of the toughest perennials for gardens is the peony. Every spring, they create luxuriant floral displays. These beloved perennials come in a wide variety of hues. Peonies come in a variety of colors, including white, yellow, pink, red, and others.
Every peony prefers full sun and soil that drains properly. If they are planted in an area with poorly drained soil or are crowded, they are vulnerable to fungus disease.
There are several variations of each of the three basic types of peony. Herbaceous peonies usually reach heights of 2 to 4 feet. They grow in the landscape as a shrubby mound with attractive flowers and dark green foliage. The blossoms emerge during the transitional period from spring to summer. Herbaceous peonies typically make a statement when spring bulb flowers are starting to fade and before summer perennials get going. Typically, flowers survive a week to ten days. The blossom festival can be extended to almost six weeks by combining a variety of early, mid, and late flowering cultivars.
Herbaceous peonies can live for 50 to 100 years on their own. They are a perennial that may add years of color to a garden.
Peonies that are herbaceous never require division. These long-lived plants flourish and blossom for years with little care if they are in the proper conditions. However, there is a misunderstanding that they cannot be parted. Nothing is more false than it is. Once they die back in the fall, peonies are simple to divide, and it’s a great way to create new plants. Just be certain that every division has three to five growth eyes (buds) in addition to three or more thick, strong roots. When replanting, pick a sunny spot with well-drained soil and add lots of compost to the planting hole and surrounding area. Make sure the buds are facing up and sticking just above the earth when you plant the divisions. If your new plants don’t blossom for a few years, don’t be disappointed.
Peonies don’t have a pressing need to flower and start a family because they can survive for over 100 years. Once they start flowering once more, they’ll keep putting on a show every spring for many years to come.
Tree peonies are a different variety of peony. The national flower of China is the tree peony. The spectacular flowers provide beauty and structure to the mixed border and can grow to be as large as dinner plates. The best part is that tree peonies can live incredibly long lives. In China, tree peonies have reportedly survived for more than 200 years. It goes without saying that appropriate planting and care are essential if you want your tree peony to enjoy a long life. Start by planting your herbaceous peony and tree peonies separately. As opposed to herbaceous peonies, which tend to bloom best when planted no deeper than when they were potted. However, because tree peonies are grafted onto herbaceous peony roots, they need to be planted much deeper. The purpose of the herbaceous roots is to give the tree peony stems enough time to establish roots before they rot.
Since the herbaceous root stock will survive and a never-ending stream of herbaceous peony suckers will grow into your tree peony, tree peonies should be planted so the graft is 4 to 6 inches below the soil surface. Tree peony don’t like to compete, so they should be planted in an area with plenty of space, direct sunlight, and well-drained soil. Add a cup of organic flower food and a half-handful of bone meal to the planting hole. Work a cup of alfalfa meal around the drip line right after planting and then every April after that to promote blooming. When determining where to put your tree peony, be selective. They dislike being transplanted after being established. Then, have patience, as it might easily take 3 to 5 years before it starts to bloom. That doesn’t seem like a long time to wait, especially because you’ll be able to enjoy blossoms every year for the following 200 years. Don’t be afraid to prune your tree peony if it is growing too tall, is too thin and lanky, or simply won’t branch out. Spend some time on the project. No more than one or two branches should be trimmed each year. The trimming can be done in the spring before growth begins, but it also works well if you do it right away after the blooming season is through. Naturally, there is no assurance that it will benefit your peony. Remember that we learn from our mistakes and that the best plant experts are those who have killed the most plants if my advice kills your pricey plant.
Peony blooms are excellent cut flowers, but if you intend to use them in centerpiece bouquets at a dinner party, you should rinse them off with the hose before bringing them inside. Nothing will make you feel worse than if your dinner guests find unwelcome guests hiding among their plate of brussels sprouts casserole! Ants that are drawn to a delicious substance on the buds frequently hide in the blooms.
Can I plant peonies after Labor Day?
Peonies are enduring garden favorites that are well-known for their lavish, early-summer blossoms. They are dependable plants that bloom for generations with little care and have an extraordinarily long lifespan. Peonies are unmatched as cut flowers. They are beautiful in their natural beauty and have a soft, enduring perfume, whether they are grown alone or in mixed bouquets.
Start with a Better Bulb
It’s simple to discern quality differences between two peony plants when you compare them side by side. Grade #1 peony, as displayed at far left, are provided by Longfield Gardens. Right on this page is a peony of grade #2. The larger root requires less time to mature into a robust plant that bears several blossoms.
Plan for Success
Peonies are low maintenance and incredibly simple to grow. Here are some pointers to assist you achieve the greatest outcomes.
Peonies thrive in the sun and perform at their best when they receive at least 6 hours of direct sunlight each day. It is preferable to put your peonies in the most sunny area possible because the more sun they receive, the better their blooms will be.
Zones 3–8 are suitable for peonies’ winter hardiness. Cold winter climates are excellent for their growth and flowering. Zones 8 may be difficult for them, while zones 9 and warmer are not advised for them. Check your hardiness zone now. The USDA Hardiness zone map can be found here.
Soil: Loose, fertile, well-drained soil is ideal for growing most plants, including peony. By incorporating compost and an all-purpose fertilizer at planting time, you can enhance the quality of your soil. Planting should not be done in wet or compacted soil.
When to Plant: Spring or fall are both suitable times to plant bareroot peonies. The plants can withstand frost, so you can plant them two to three weeks before the last day of frost. You can plant potted peonies at any time of the growing season.
Make a 12-by-12-inch hole. Compost and general-purpose granular fertilizer should be added after loosening the soil at the bottom of the hole (follow package directions).
Place the peony root in the hole with the eyes (the growth points) no lower than one inch below the surface of the soil. Peonies that are planted too deeply may continue to grow but not blossom. Add soil over the root and water as necessary.
Planting Tips for Peonies
Peonies need full sun in order to produce a profusion of blossoms. Even though certain types may withstand moderate shadow, fewer flowers bloom in general when there is less light.
Peonies should be planted in soil that is fertile, well-drained, and has a pH range of neutral to slightly alkaline. They will eventually grow a substantial root system and become challenging to relocate. Spend some time placing your peonies in a location where they can flourish for many years. The plants are reasonably drought resistant once they are established.
Continual Gardens Perennial gardens work well with peonies. Their year-round gorgeous dark green leaves. Peony leaves occasionally turn crimson or gold in the fall.
Fence lines and hedges To create a low hedge for enclosing a space, defining one side of a garden, or edging a walkway, peonies can be planted in a row. They also look fantastic when planted at the bottom of a chain link or split rail fence. As a sturdy fence will restrict airflow around the plants and increase their susceptibility to foliar diseases, avoid growing them next to one.
Plantings for the foundation and shrub borders The presence of a peony is comparable to that of a tiny shrub. Peonies may grow practically anyplace in your landscape as long as they are planted in well-drained soil, receive enough light, and have sufficient air circulation.
What to Expect from Peonies
All peonies bloom in the first few weeks of summer, however each cultivar blooms at a different period. The peony season can be prolonged by a month or more if you plant a mixture of early, mid, and late season bloomers. Other early summer perennials like iris, alliums, and roses pair well with peonies. The greenery keeps borders looking full and gives other flowers a lush background.
Most peony mature at least three feet tall and three feet wide, depending on the type. Therefore, it’s crucial to provide them freedom to expand. Peonies will maintain their flowers straight if a support cage is placed all around them. Use a pre-made peony support or create your own from steel or mesh reinforcing wire or wood slats. Early in the spring, before the plants reach a height of 12 inches, supports should be installed.
Carefree peony plants that hardly ever experience insect or disease problems. A young peony plant needs two to three years to become established, but once it does, it will reliably blossom each year.
Fantastic cut flowers are peonies. The majority of cultivars are also incredibly fragrant, and they remain for days in a vase. When the buds are in the “marshmellow” stage, peony stems can be removed and kept in water in the refrigerator for a few weeks. After many days, the buds on the stems brought into room temperature will begin to open.
Caring for Peonies are they Bloom
Use scissors to cut off the wasted flower heads and the top six to eight stems once the blossoms have faded “that stem. This will prevent the plants from forming seed heads and keep the plants looking tidy. The plants will be able to produce the energy they require for the blossoms of the following year if as little foliage as possible is removed.
When the leaves start to turn yellow in the fall, trim all the stems to within an inch or two of the ground.
When the stems are about 6 inches long in the spring, fertilize peonies “tall. Around the base of each plant, dispense roughly a half cup of all-purpose granular fertilizer. To avoid having the eyes buried too deeply, remove any mulch or other debris from the plant’s crown.
How to Divide a Peony
Peonies can stay undisturbed for several years in the same location. If the plants must be moved, do so in the fall when they are beginning to enter dormancy rather than in the spring when they are just starting to grow again. Trim the leaves, which may be up to three feet wide, then carefully remove the entire root ball. Dig carefully, avoiding uprooting any roots, and dig deeply. Replant right away, and give it lots of water.
Plant division can be done in the fall or very early in the spring. One method is to remove the entire root ball as previously said, then place the clump on a tarp. After cutting the clump into sections with a sharp knife, quickly replant each section. Work swiftly and gently, causing the fewest potential injuries to the fleshy roots.
The alternative is to cut one or more portions of root from the mother plant using a sharp spade. Once more, plant these divisions again right away, and during the first growth season, irrigate as necessary. Though you may often anticipate losing at least one season of blossoms, plants will recover more quickly the less the roots are touched.
