Herbaceous peony and tree peonies are the two main varieties of peonies that can be grown. Select intersectional peonies, a cross between herbaceous and tree peonies, if you prefer a bit of each. Mid-spring through mid-summer sees peony blooming. Despite being brief, the flowering season is striking, with huge, single or double flowers bursting in a rainbow of hues. Depending on the species, peonies can be found in U.S. Department of Agriculture plant hardiness zones 3 through 10.
Where do peony thrive?
Now that you are aware of the distinctions between the two primary Peonies, let’s approach your choice based solely on the available information.
Location & Climate: If you reside in the extreme south or north, temperature and humidity may have a significant impact on your choice of peony.
Garden peonies will thrive if you are in a northern region with a shorter, cooler growing season. Garden Peonies are especially popular in Zones 3 through 8, where they may require a little more care.
- A tip for getting them to behave perfectly if you live in the deep south is to select an early-blooming type that will go into flower before the summer heat arrives.
- In the same way, a late-blooming Garden Peony is likely to succeed better in zone 3’s northernmost regions, where temperatures will have warmed up enough for it to flourish during their peak bloom period.
Available Sunlight: Unlike Itohs, which love dappled light and can even take part-sun, Garden Peonies require full sunlight. As a general rule, your garden will be exposed to more sun and humidity the further south you live. You should give your peony more room in hotter, brighter climates so they may receive more air circulation and perhaps a little less sun than usual.
In Zone 11, can peonies be grown?

What’s fresh: Herbaceous and tree peonies are crossed to create itoh hybrids, also known as intersectional hybrids. They can reach a height of 3 1/2 feet, produce flowers in lavender, pink, copper, yellow, or cream, and bloom for a longer period of time than typical herbaceous varieties.
Since their stems are more thicker and more sturdy than those of herbaceous species, they are effective in supporting large cups of petals.
Where to grow: Peonies do best in cooler regions (Sunset zones 111; A1A3), where the winters are particularly chilly. However, some will thrive in warmer environments (see list below). Under zones 1420, all are worthwhile attempts in dappled shade. There, give the plants plenty of water and midday shade.
When to plant: In late April in warmer climates, plant container-grown plants; in May or June in colder climates. In 5-gallon containers, 3-year-old peony should blossom more.
Spring or fall, from containers used for nurseries: Place the plant in the ground with the top of its rootball level with the dirt after loosening the soil and adding copious amounts of compost, being careful not to disturb the plant’s delicate feeder roots. Or move it into a sizable (18 to 24-inch diameter) container that is deeper on the outside than the inside.
Plant herbaceous peony roots with eyes 2 inches deep in cold climates and 1 inch deep in warmer climates in the fall. In cold climates, itoh hybrids should be planted 3 inches deep; in warmer climates, 2 inches deep.
How to feed and water: Water frequently. When the first leaves emerge in the spring, fertilize with a low-nitrogen fertilizer (such 5-10-10) and then once more when the final flower has faded.
When to pick: Cut stems just as flower buds start to open to harvest blossoms for bouquets; leave at least three leaves on the plant to feed it for the following year. Blooms will keep for up to a week in vases. Although Itoh hybrids generate more flowers per stem as the plants become older, the majority of cultivars only produce one bloom per stem.
After flowering, prune down herbaceous and Itoh hybrid peonies in the fall; fresh growth will appear in the spring.

For cold climates, pick: There are three new Itoh hybrids—crosses between tree peony and herbaceous peonies—called “Bartzella,” “Pink Double Dandy,” and “Yellow Doodle Dandy.” Bartzella has unusually enormous, bright yellow blooms.
Four herbaceous favorites for cool or warm climates include “Blaze,” a vivid red single, “Festiva Maxima,” a white double with crimson flecks in the middle, “Sarah Bernhardt,” or “Sea Shell” (satiny pink single).
Shop: Purchase plants (itoh hybrids can cost up to $100 at nurseries, while ordinary herbaceous can cost $40), beginning in late April in warm climates and May in chilly ones. Plants that are three years old and are housed in five-gallon containers will reliably blossom.
Visit and purchase: The 200 or so varieties of herbaceous and tree peonies at Chateau CharMarron Peony Gardens (5335 Sierra Rd., San Jose; 408/251-7048) begin flowering in late March and last through June. Visit Adelman Peony Gardens next month (May 1–Jun 15; 5690 Brooklake Rd. N.E., Salem, OR; 503/393-6185) to see 300 varieties spread across 10 acres.
In Zone 9, can peony survive?
We’ve known for a long time that many of our clients have had success producing peony in USDA zones 8 and 9. We recently reached out to several highly knowledgeable farmers in these regions of the country for some specific guidance on how to get peony to thrive there, but due to the extreme and unprecedented conditions encountered in some places of these zones in the last five years, we recently contacted them.
We would be delighted to hear from you if you have any other growing advise for peony in zones 8 or 9!
Peonies can they grow anywhere?

One of the most well-known and cherished perennials is the peony. Given their luxurious beauty and smell, hassle-free nature, and longevity, this is hardly unexpected. Peonies can be found flourishing throughout the nation. Many kinds can even withstand a winter in zone 2 (which has a low of -50 degrees F).
A peony may bloom for up to 100 years with little to no care if it is content and in a good location. This indicates that it is worthwhile to invest some time up front in selecting the ideal planting area and improving the soil. However, there are several tales of abandoned peony plants being discovered in blooming condition next to ancient cellar openings in the woods. However, if peonies have the best growing conditions, they will be healthier, more vivacious, and more floriferous.
When selecting peonies, pay close attention to the “singles,” which are lovely and fragrant but don’t need as much staking.

In zone 10a, how are peony grown?
“Good day, Adriana I adore reading your blog. I appreciate all the good information very much.
Herbaceous peonies are something I’d want to plant. Three herbaceous ones that I tried to grow once didn’t take. In Southern California’s Zone 10A, do you have any tips on how I can grow them? or even if you believe it is conceivable. Any guidance and assistance you can provide would be greatly appreciated.”
In hotter growing zones, I have heard of individuals covering their peony with ice in the winter, but I don’t have a lot of details on how they did it (how frequently, how much ice, how many days/weeks/months?). Growing a flower seems like a lot of work to me as well. Therefore, I probably wouldn’t advise using that strategy.
I strongly advise you to try growing an intersectional peony. They are a hybrid of a tree peony and a herbaceous peony that can thrive in somewhat warmer climates (just like their tree peony parents). If you’re interested, tree peonies might be an alternative, but I genuinely believe intersectional peonies will be simpler to grow. While tree peonies are typically grafted and take longer to establish, intersectional peonies are grown on their own roots (which may be hard to do in a challenging climate).
Regardless of the peony variety you select (herbaceous or intersectional), I advise planting them very shallowly. The pinkish “eyes” should be at ground level and being able to view them over the winter is good, but you want to conceal the roots (even suggested in warmer growing zones). For the “eyes” to set bud in the winter, it must be chilly.
Plant your tree peonies deeply if you choose them. It is necessary to bury their “eyes” or growing buds in the ground. The better is to plant a tree peony deeper. With the real stem (woody) component of the peony placed 3-5 inches beneath the soil surface, the plant’s roots should be well rooted in the ground. This should enable the tree peony to begin producing more of its own roots from the stem that has been buried.
Intersectional Peony ‘Bartzella,’ a Gold Medal Winner from the American Peony Society, is a fantastic intersectional peony to try if you’re interested. It consistently produces an abundance of buds and flowers, and the blossoms are absolutely stunning, with bright, full, striking yellow blooms! These days, you may purchase it for a respectable cost (since it has been around for a while now). To find out where to buy it, look at my intersectional peony price list.
I sincerely hope that this information is helpful. In the future, I’d love to learn more about your garden. Please let me know how your experience with growing peony goes!

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
