There’s nothing quite like a peony in full bloom: those big, fluffy flowers look like they were made for daydreams and wedding bouquets. Whether you’re wooed by their romantic petals, heavenly scent, or the fact that they can live longer than most humans (seriously!), peonies are a gardener’s dream come true. 

In this guide, we’ll show you how to grow peonies that come back stronger each year, plus where to plant them, how to extend their bloom season, and why they’re the floral royalty of any garden bed.

Peonies are flowering perennials best planted in autumn for those outrageously beautiful flowers that bloom from spring to summer. They make magnificent cut flowers and also bear lovely foliage that stays green. 

Planting

Where to Plant Peonies

Peonies make fine sentinels lining walkways or a lovely low hedge. After their stunning bloom, the peony’s bushy clump of handsome, glossy green leaves lasts all summer and then turns purplish-red or gold in the fall. It is as stately and dignified as any flowering shrub.

In mixed borders, peonies bloom with columbines, baptisias, and veronicas and combine well with irises and roses. Plant white peonies with yellow irises and a froth of forget-me-nots; set off pink peonies with blue nepeta or violets.

  • Peonies are not too fussy, but choose your location wisely as they resent disturbance and do not transplant well.
  • Peonies like full sun, and though they can manage with half a day, they bloom best in a sunny spot that gets 6 to 8 hours of sunlight each day. In southern states, provide some shade.
  • Provide shelter from strong winds, as peonies’ large blooms can make them top-heavy. (Use stakes to hold them up, if necessary.) Don’t plant too close to trees or shrubs, as peonies don’t like to compete for food, light, and moisture.
  • When growing peonies, plant in deep, fertile, humus-rich, moist soil that drains well. The soil pH should be neutral.
  • They are cold hardy, so any place you need an overcoat makes them happiest—they require a cold period for bud formation, a frustration to some southern gardeners.

When to Plant Peonies

Peony plants require little maintenance as long as they are planted properly and establish themselves. Note, however, that they do not respond well to transplanting, so you should plan your planting site accordingly.

  • Plant peonies in the fall: in late September and October in most of the U.S., and even later in the fall in Zones 7 and 8 (Find your planting zone here).
  • If you must move a mature plant, fall is the time to do it—specifically, when the plant has gone dormant.
  • Peonies should be settled into place about 6 weeks before the ground freezes.
  • Although it’s certainly possible to plant peonies in the spring, spring-planted peonies don’t do as well. Experts agree: they generally lag about a year behind those planted in the fall.

How to Plant Peonies

  • Peonies are usually sold as bare-root tubers with 3 to 5 eyes (buds), divisions of a 3- or 4-year-old plant.
  • Space peonies 3 to 4 feet apart to allow for good air circulation between the plants. Stagnant, humid air can be a recipe for disease to develop.
  • Dig a generous-sized hole, about 2 feet deep and 2 feet across, in well-draining soil in a sunny spot. The soil will benefit from the addition of organic material in the planting hole. If the soil is heavy or very sandy, enrich it with extra compost. Incorporate about one cup of bone meal into the soil. Learn more about soil amendments and preparing soil for planting.
  • Set the root so the eyes face upward on top of a mound of soil in the hole, placing the roots just 2 inches below the soil surface. Don’t plant too deep! (In southern states, choose early-blooming varieties, plant them about 1 inch deep, and provide some shade.)
  • Then, backfill the hole, taking care that the soil doesn’t settle, and bury the root deeper than 2 inches. Tamp the soil gently.
  • When planting a container-grown peony, cover it no deeper than it grew in the pot.
  • Water thoroughly at the time of planting.

Growing

When Is Peony Season? When Do Peonies Bloom?

Peonies bloom from late spring through early summer, depending on your location and the variety of peonies you’re growing.

Many nurseries offer early, midseason, and late-blooming varieties, allowing you to extend the peony season over many weeks and enjoy those lovely blooms for as long as possible!

Peonies are hardy to Zone 3 and grow well as far south as Zones 7 and 8. In most of the U.S., the rules for success for growing peonies are simple: provide full sun and well-draining soil. Peonies even relish cold winters because they need chilling for bud formation.

How to Care for Peonies

Like children, young peonies take time to develop. They usually need a few years to establish themselves, bloom, and grow. And soon enough, they venture out on their own, mature and well-adjusted… Wait, no, that’s just children.

Peonies thrive on benign neglect. Unlike most perennials, they don’t need to be dug and divided every few years.

  • Spare the fertilizer. Work the soil well before you plant, mixing in compost and a little fertilizer, and that should be enough.
  • If your soil is poor, apply fertilizer (bonemeal, compost, or well-rotted manure) in early summer after the peonies have bloomed and you have deadheaded the flowers. Don’t fertilize more than every few years.
  • Help the stems. If peonies have any structural weakness, it’s their stems, which are sometimes not strong enough to support their gigantic blossoms. Consider metal peony rings or wire tomato cages that allow the plant to grow through the center of the support.
  • Deadhead peony blossoms as soon as they begin to fade, cutting to a strong leaf so that the stem doesn’t stick out of the foliage. 

Fall Peony Care

  • After peony leaves begin to fade, side-dress plants with a balanced, slow-release fertilizer; avoid fertilizing with high nitrogen.
  • After frost, the foliage will die back completely. Cut the plant to the ground in the fall to avoid overwintering diseases.
  • Don’t smother peonies with mulch. Where cold temperatures are severe, for the first winter after planting, mulch VERY loosely with pine needles or shredded bark. Remove mulch in the spring.

Dividing Peonies

While peonies don’t require regular division like some perennials, fall is the best time to divide or transplant them, especially if your plants have become too large, are producing fewer blooms, or you simply want to share them with friends. Begin by cutting back the foliage to just an inch or two above the ground. Then, using a spade or garden fork, carefully dig a wide circle around the root system to avoid damaging the thick, tuberous roots.

Once you’ve gently lifted the plant from the soil, brush or wash off the dirt so you can clearly see the root structure, the most important part to identify is the “eyes”—these are the small, pink or white growing buds that resemble the eyes of a potato. Each healthy division should contain at least 3 to 5 eyes and a good portion of strong roots to support new growth. Fewer than three eyes may delay blooming by a few years.

When replanting, choose a location with full sun and well-draining soil. Plant the peony divisions so that the eyes sit no more than 1 to 2 inches below the surface. Planting too deep is a common reason why peonies fail to bloom. Water thoroughly after planting and mulch lightly to protect the roots over winter.

Harvesting

Keeping Peony Flowers in a Vase

Peonies make wonderful cut flowers and last more than a week in a vase. For best results, cut long stems in the morning when the buds are still fairly tight; look for the “marshmallow” stage, when buds are soft but not fully open. Use clean, sharp pruners and snip just above a set of healthy leaves to encourage continued growth on the plant.

To store cut peonies for later use, wrap the stems in a damp paper towel and place them in a plastic bag in the refrigerator. They can be stored this way for several days to even weeks. When you’re ready to use them, recut the stem ends at an angle under running water or submerged in water. Then, place them in a clean vase filled with lukewarm water to help the blooms rehydrate and open fully.

Keep your vase in a cool spot out of direct sunlight and change the water every couple of days to prolong the blooms’ beauty. See more tips on keeping cut flowers alive longer.

Pests and Problems

Peonies are generally very hardy. Plus, peonies are also one of many deer-resistant plants you can grow in your garden.

However, they are susceptible to:

FAQ

Why are there ants on my peonies?

Many gardeners wonder why so many ants crawl on the peony buds. Don’t worry! They are just eating the peony’s nectar in exchange for attacking bud-eating pests. They are attracted to the sugary droplets on the outside of flower buds or to the honeydew produced by scale insects and aphids. Never spray the ants; they’re helping you by keeping your peonies safe!

Why are my peonies not blooming?

There are a few reasons why your peonies fail to bloom. If it is planted too deep (the eyes should only be about 2 inches below the soil), it will lead to beautiful foliage but very few flower buds. Depending on your fertilizing schedule, it may be receiving too much or too little fertilizer. Also, remember not to remove the foliage too early in the season. Wait for the foliage to die back naturally before removing it after the first frost. 

Peonies need a certain amount of cold weather in the winter to set buds and to flower. If you live in a warmer location, your peonies may be getting just enough cold weather to produce the buds, but not enough to make them flower. 

Bud blast can also be the cause since it results in buds turning brown and shriveling up. The best thing to do is to make sure it has the ideal growing environment in terms of sun, fertilizer, cold winter temps, and proper planting depth.

Can I plant the seed pods on my peonies?

The pods that remain on your peonies will contain seeds. You can collect the seeds when the pods turn dark brown and slightly crack open. To make sure that you don’t lose seeds to birds or weather, tie nylon or small mesh bags around maturing seed pods before they split open to catch any seeds that may fall. Ripe seeds can be planted immediately after collection. 

Peony seeds require a warm/cold cycle to produce their first true leaves in the spring. In nature, seeds are dispersed on warm late summer to autumn days and quickly germinate. By winter, they form small roots. They are then dormant during the winter before emerging in the spring. Press peony seeds into the ground at no more than a 1/2 inch depth. Then cover with an inch of wood chips to provide protection. 

You can certainly dry and save seeds for future planting, but dry seed takes longer to hydrate than fresh seed, and dormancy is more difficult to break.

 Can I grow peonies indoors?

Yes, you can, although they are best grown outdoors. Inside, you’ll need to provide enough light (about 6 to 8 hours); if you don’t have enough natural daylight, a grow light can help. It is also necessary to give them a period of cold (about 3 to 6 weeks, depending on variety, of temperatures between 32 and 40 degrees F) over winter, which is needed for flowering. If you live in a cold climate, this can sometimes be done by leaving the pot in a cool garage or shed, with the top of the soil covered with straw to protect the roots once plants are dormant; remove the straw at the first sign of growth in spring. 

Select a variety of peony that is shorter (not those that can grow to 4 to 6 feet, for example); if you live in a warm climate, choose a variety that does not need as long a period of cold (aka “chilling hours”) over winter. Plant in fall or spring. Choose a heavy pot (ideally, not terracotta) that is about 18 to 24 inches wide and deep, with drainage holes, and fill with rich, well-draining potting soil. Keep soil evenly moist but not soggy; when plants are established, you can let the soil dry out a tiny bit before watering deeply.

How long will it take my peonies to bloom?

Peonies typically take 2 to 3 years to bloom after planting, especially if planted from bare roots. The first year is focused on establishing strong roots, and blooms are usually sparse or absent. By the second or third year, you’ll see more consistent and fuller flowering.

Types

In the 1930s and 1940s, plant catalogs listed only three peony choices: white, crimson, and rose pink. Today, thousands of varieties are available.

There are six main peony flower types: anemone, single, Japanese, semidouble, double, and bomb. Fragrances vary as well—some plants, such as ‘Festiva Maxima’ and ‘Duchesse de Nemours’, have intoxicating rose-like scents, while others are lemony or have no scent at all.

There are six different types of peony flowers.

Peonies bloom between late spring and early summer, but you can plan your garden for a successive display of flowers from mid-May to late June by planting various varieties. Here are some choices:

  • Anemone (an advanced Japanese form)—‘Laura Dessert’: cream/pale lemon to white; strong fragrance; early-season
  • Single (one row of petals)—‘Sparkling Star’: deep pink; early- to midseason
  • Japanese (decorative centers)—‘Carrara’: white, with soft yellow centers; fragrant; midseason
  • Semidouble (five or more guard petals and prominent centers)—‘Pink Hawaiian Coral’: pink to coral rose form; slight fragrance; early-season
  • Double (large petals, needs support)—‘Candy Stripe’: white, with red streaks; slight fragrance; mid- to late-season
  • Bomb (large, like a scoop of petals)—‘Angel Cheeks’: soft pink; slight fragrance; midseason
  • Consider, too, the Itoh peony: Named after its developer, Japanese botanist Dr. Toichi Itoh (d. 1956), this flower is a cross between a herbaceous (bush) peony and a tree peony. Its large single, semidouble, and double blooms appear later in the season and last longer than traditional peonies.

Wit and Wisdom

  • After at least 2,000 years of cultivation and breeding in China, the ornamental peony was introduced to Europe and America in about 1800.
  • Two peony species are native to North America. Brown’s, aka western, peony ranges from California to Montana, and the California peony is found along the Pacific coast of that state.
  • The peony is the state flower of Indiana.
  • Peonies are said to symbolize a happy life and a happy marriage. See more flower meanings here.
  • Marco Polo described peony blossoms as “roses as big as cabbages.”
  • According to the ancient practice of phenology, when peonies blossom, it is safe to plant heat-loving melons, such as cantaloupe.
  • Peony petals are edible. Add to summer salads or use as a garnish for lemonade and iced tea. Read more about edible flowers!
  • Once settled in the garden, peony plants can be content for generations. Some have been known to thrive for a century!

Had I but four square feet of ground at my disposal, I would plant a peony in the corner and proceed to worship.  –Alice Harding, The Book of the Peony

Unfortunately, it most likely die/do nothing. In the fall if your friend digs back some of the surrounding topsoil, with a shap knife, she can cut off a root section with at least three eyes. Plant that rooted section in a hole generously amended with fertilizer (All purpose or with high Phosphorus, the 2nd number listed on the package) with the yeyes about an inch from the surface, and in a year or two you will get blooms. While beautiful, peonies are finicky. Hope this helps!

I live in central Pa. My peonies have got a "moldy" look to their leaves and there are tiny holes in the leaves as well. What is wrong with them and do I need to replace them?

Hi Karolynne,

It's probably mildew. Humid weather is usually to blame for this. Make sure your peonies have good air circulation and you can try to spray the plants with neem oil. In the fall cut the peonies back and discard the "moldy" leaves.

The holes are most likely from slugs. See our slug page at http://www.almanac.com/content/slugs for ways to get rid of them.

My parents house on Long Island had beautiful peonies that we did nothing to, just enjoyed. I now live in Albuquerque and have tried to grow some here. My mother-in-law gave me a root (tuber?) that never did anything. Last year we bought 4, and 2 were growing but one seems to have died off. We planted on the north side of the house, because it's so hot here in the summer. I'm afraid it will burn up if planted in full sun. (I'm not kidding, one year our plastic hummingbird feeder melted). Our soil is pretty bad, but we used a whole bag of Miracle Grow when we planted. Is it possible to grow healthy peonies here at all?

Yes, you can grow beautiful peonies in Albuquerque. They prefer well-drained, loamy garden soil. It's wise to protect them from the hot sun in the summer and a north or east side location in best. Make sure to water the plants often during the summer months.

Care tips say "Cut the foliage to the ground in the fall to avoid any overwintering disease." If relocating plants from one garden to another, should I cut foliage down before digging up or after replanting? Thanks!

Transplanting peonies in the fall gives the roots time to re-establish before winter. September is a good time. Cut the peony stems near ground level. Have the planting holes ready. They should be large enough to comfortably accommodate the plant’s root system. When ready to transplant, gently dig around and under each plant. Get out as much of the rootball as you can and replant as soon as possible. Position the peony plant in the hole so the buds are one to two inches below the soil surface. Fill the hole with soil, firming the soil around the plant as you backfill. Then water thoroughly. Space peonies three to four feet apart. Keep in mind that the transplanted peonies may not bloom as well (or at all) the first season, but that they will recover.

My great grandma had peonies they were planted prior to 1968 when she died. They are in my grandma's yard and now she has died. We would like to dig them up and move them from Kentucky to Arkansas. Any advice as I don't want to kill this plant

Peony roots can be transported bare, meaning not in soil. Cut back the foliage and gently dig around and under each plant. Get out as much of the rootball as you can. They should be stored during transplant so as to not dry out--try packing them with dampened moss or in damp newspaper. Keep in mind that the transplanted peonies may not bloom as well (or at all) the first season, but that they will recover.
