Are peony challenging to grow in California?
The peonies that resemble little shrubs and have stunning, vivid white, pink, or magenta blooms in the late spring and early summer are known as herbaceous peonies. In USDA zones 2 through 8, peonies are a longtime favorite of gardeners. Many gardeners in California long to add peonies to their landscape but think they won’t be successful since peonies require a chilly dormant period. You can take a few actions to promote peony growth and bloom in California.
What time of year do peony bloom in California?
The California peony is in season from December to May. It is a perennial, which means it grows continuously between dormant seasons. Therefore, the California peony’s limited availability (mostly restricted to spring) adds to its attractiveness, much like its conventional sibling more frequently seen in peony bouquets.
The time has come to go wild California peony hunting, so be on the lookout when you start to see fresh-cut peonies for sale!

The peony has the fattest, most delicious petals and rich green foliage, making it outrageously attractive when it is in bloom. From spring to summer, savor stunning floral displays. Learn how to care for, grow, and plant peony.
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
Can peony thrive in warm weather?

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.
Do peony grow in Orange County, California?
Why do we desire that which we lack? If we have straight hair, we desire it curly. When we reside in apartments, we desire a view. Gardeners in other regions simply wish they were gardening here, but if we plant in Southern California, we want peonies.
Monrovia Nursery has shown warm-weather gardeners love by providing us with about every plant we could ever desire. The Itoh peony, which bloom in warm climates like ours, are the newest in their collection.
I’ve had positive feedback from Steve Hampson, the former president of the American Daffodil Society, and Ron Vanderhoff, general manager of Roger’s Gardens. Both claim that Itoh peonies planted in Orange County gardens last year have returned this spring and are bursting with buds that are prepared to blossom.
Nicholas Staddon, the Monrovia Nursery’s vice president of new plants, claims: “To find out where plants can survive, we conduct several trials and are always pushing the limits.
“I suggested that we follow the Itohs through Southern California when we came across them. Plants have bloomed in warmer San Diego locations as well as against the San Gabriel Mountains.
Itohs first appeared in the 1940s. The intersectional plant was created in 1948 by Toichi Itoh of Japan, who was the first to cross a tree peony with a herbaceous peony. After his successful cross, Itoh passed away, and it took years of selection and additional breeding by others to bring Itoh peony to market.
Once established, an Itoh peony plant can produce up to 50 blossoms the size of a dinner plate. The intersectional brings the best of both worlds—large flowers from the family of tree peonies and the perennial habit handed down by herbaceous types.
Itoh peony should be planted in full to partial light, require regular watering, and require more attention and water in hot weather. They bloom in the middle of May.
They thrive in slightly acidic soils, which are simple to create by adding organic compost to the backfill or growing them in containers.
Itoh peonies hate to be relocated, so place your peony in the ideal location from the beginning. Additionally, don’t consider splitting them up after a few years; this rarely works.
Staddon advised, “Put them in containers that are at least 24 inches wide if you’re unsure where to plant yours. A strong root system supports them.
They can tolerate full sun in Oregon. They require early sun in Orange County’s interior, and they can possibly tolerate a few more hours of full sun each day at the shore.
A 5-gallon, three-year-old Itoh peony costs in the $80 to $100 range, which is reason enough to cultivate them carefully. This means that you must want one more than any other plant in the world.
Pruning can be challenging. You must descend to the plant’s base toward the end of the growing season, say in November, to determine how far back the stems have perished. Trim existing stems 2 to 3 inches above the point at where the woodiness ends. Additionally, you’ll see that the crown may be sprouting new eyes, much like a herbaceous peony. Those will be fresh stems for the following season.
Feeding should begin very early in the spring and continue every 40 days through the month of August. GroPower is used by Staddon.
Markets in Southern California carry three hybrids: Keiko, a light rosy pink; Takata, a rose-colored bloomer with orange eyes; and Misaka, a peachy bloomer.
“According to Staddon, Keiko has secondary buds developing lower on the stems, which is extremely uncommon in the peony world. “You will receive enough flowers for several weeks.
How are peony cared for in Southern California?
Once planted, peonies don’t require much maintenance. Till they take root, keep the soil moist but not soggy. Once they are established, you can reduce watering to twice weekly, but the warmer summers in Southern California will require more irrigation. It is a good idea to provide some shade for your peonies until they are established if you reside in an especially warm, sunny environment.
To prevent competition for nutrients, routinely deadhead your peonies and maintain your garden weed-free. Cut down herbaceous peonies in the fall to encourage regrowth in the spring if you’re cultivating them. Tree peonies are sometimes a better option for people who live in coastal Southern California since they require fewer freezing hours in the winter. You don’t need to prune tree peony in the fall if you cultivate them.
