The USDA zone information is one of the best resources we have as gardeners to assist us plan our planting calendar.
The average last frost date and the coldest anticipated temperature for our region are the two most crucial facts that the zone information provides.
To determine the best time to plant peony, consult the USDA zone information for Zone 10b.
Planting Calendar for Peonies
Peonies’ resistance to frost
The ideal time to plant them is:
Peonies can be planted slightly earlier in the year than other frost-sensitive plants because they tolerate a small amount of cold well.
If you don’t want to take any chances, you should really hold off until March.
Probably September is the last month to grow peony and anticipate a decent crop.
If you wait any longer, your peony might not get an opportunity to fully grow, so you probably shouldn’t.
Last Frost Date
Remember that the USDA’s Zone 10b information is only an average, and our actual date of last frost might vary significantly from year to year.
Be prepared to cover your peonies if we have a late frost because, in Zone 10b, the last frost usually occurs after January 31.
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.

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.
Grab a peony.
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 what kind of climate may peony flourish?
Peony flowers offer a brilliant splash of color to the landscape and are beloved by most gardeners for the beauty of their magnificent blossoms, their lovely smell, and their robust foliage that changes shades over 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.
Nevertheless, choosing the best peony might be challenging given that there are over 3000 cultivars of peonies available (!!!). If you reside in a warm spring climate, you could want to take into account peonies that can endure the rain or the heat.
Peonies that can withstand rain: Springtime provides beautiful brightness as well as downpours that could splatter and destroy peony blossoms over the grass. The opulent, huge peony blossoms frequently gather and retain a lot of water, overloading the stalks. Even strong stems can fall or break because of their propensity to arch toward the ground. Sadly, peony rings do not protect the blossoms from being broken by a heavy downpour. The only way to keep the lovely blossoms upright above the foliage may be to stake each stalk. Many of us, though, are unwilling to provide that kind of attention.
Heat-resistant peonies: Peonies thrive in chilly areas (Hardiness zones 3-8). For them to flower successfully, they require a significant duration of winter cold (to induce dormancy) and not too much heat and humidity during the flowering season. Choose early-blooming types that bloom before the arrival of hot weather if you live in a southern state. Choose plants with single or semi-double flowers, and put them in a cool, shaded spot about an inch deep (so they get the tiniest frost nip).
Here are several peonies that have demonstrated heat or rain resistance and could be the showpiece of your spring garden.
What conditions favor the growth of peonies?
I love peonies, but I live in a region where it could be too warm for them. Can I grow peonies in my area? is a common query. You can use the following suggestions to decide whether peonies are likely to thrive in your area.
Garden peonies prefer cold winter weather and need at least 30 days in a row with temperatures below freezing. It is not necessary for it to freeze and thaw because the objective is to maintain the roots’ chilly temperature. Before purchasing any kind of peony, think about whether you can feed your plants with enough cold weather during the dormant season so they can grow and blossom.
Choose peony kinds that bloom early in the season, before your late spring/early summer weather becomes too hot, if you live in zones 7 and 8. The description of each cultivar on this website specifies whether it blooms early, midseason, or late. Recognize that planting in zone 8 is a bit of an experiment because it indicates the edge of weather where peonies may successfully blossom. Peonies that bloom in the middle to end of the season may endure in warm climates, but they are not likely to reliably and prolifically blossom.
Your peony roots’ planting depth affects how many flowers you get. The “eyes” or tiny pink or red growth points should be planted 1 to 2 inches under the earth, with the deeper end of the spectrum being preferred in the coldest locations (zones 3-5). Zones 6 and 7 and even zone 8 gardeners who plant just 1″ or even 1/2″ deep will have the best results.
Site your peony in hot regions where they’ll get a little relief from the worst afternoon sun. The best setting is one with filtered late-day light.
Remember that peonies produce numerous large, typically heavy flowers when they are mature, wherever they are grown. (Which, I presume, is one of the reasons you adore them.) The thickly petalled double and semidouble blossom varieties have a propensity to collect rain or sprinkler water. Young plants can have ring or crisscross supports placed around them to allow shoots to grow through, stabilizing blossoming stems, and eventually blending in with the dense foliage. On the plus side, if your peonies droop in the rain, it gives you the perfect justification to cut them to your heart’s content, carry bunches to work, share them with friends, and arrange bouquets all over the house. That would be really terrible.

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
