Gardeners that take their hobby seriously enjoy a challenge, especially when it comes to zones, frost, temperatures, and other dull scientific information.
A true plant enthusiast will buy two plants if you tell them you can only grow one. They’ll test it if you say it’s too temperate or tropical. They’ll dream about it all night if you tell them it’s too hard for them to grow. Gardeners enjoy taking risks.
One of these regional difficulties is how to cultivate and bloom peonies in Southern California. Just last week, I heard from two people who took on the peony challenge: Kathleen and Katharine. To my amazement, both mentioned having success with the Itoh Hybrids line of peony.
Kathleen relocated to north San Diego County from a colder climate a number of years ago. She was severely missing flowers.
“Last year, I bought one of the new Itoh Peonies on a whim, just to appreciate the stunning blooms,” Kathleen said.
Since they are brought here from colder climates where they have already experienced a hard winter, it is not all that surprising for a freshly acquired peony to blossom the first year.
But Kathleen’s peony didn’t act as one might anticipate. When it was no longer in flower, Kathleen put it under the cover of a tree fern and promptly forgot about it.
Kathleen added, “I utterly disregarded it by letting it sit in water.
A few weeks back, when I saw some new growth, I finally realized what had happened to the poor plant. I quickly placed it into some sunshine, and last week, buds appeared!
A reblooming peony that is barely half a mile from the coast, doesn’t require any particular care or winter protection, and only needs lots of water? That shouldn’t be possible, I think.
Then I received a message from Katharine, who has been cultivating peonies in her Glendora garden for the past five years. She has accumulated a sizable collection over that time—probably more than 25 plants—and has been able to enjoy their blossoms through mid-June.
Itoh peonies are quite powerful early blooming types, I’ve learned,” Katharine noted.
She provides mulch, fertilizer, and weed control for her peonies. She claims that none of her plants have an insect or snail problem.
After this spring, according to Katharine, she realized she probably doesn’t need to pamper her peonies quite as much. Katharine gave her justifications.
She remarked, “I forgot that the Itoh peony was sleeping underneath the site we were going to tidy up one day when I ordered my gardener to plant a Camellia.
Accidentally, the dormant plant was unearthed. The root ball, which resembled cheese curds, had been lying on the grass for a few weeks and he had no idea what it was. The bulk was finally scooped up, placed in a plastic container, and set on my driveway. It is flowering much sooner than last year since it loves the warmth of the concrete.
On the north side of her home, Katharine produces Itoh peony in full sun with some morning shade.
She claimed that the plants not only seemed to enjoy her heavy clay soil, but also the aromatic potting soil.
These peony success stories, which both include the Itoh peony series, may not be coincidences.
These peonies, which bear the name Toichi Itoh in honor of the first person to successfully hybridize a tree peony with a herbaceous peony, are treasured for their enormous, gorgeous blooms and rich green foliage.
Itoh peony have a vigorous, domed growth habit and produce enormous, double blooms with lacy, dark green foliage that is resistant to disease. They reach a height and width of around three feet, and like all peonies, they get better with age. Because itoh peonies can have both primary and secondary buds, they also have a longer flowering time.
Katharine, a peony expert, claimed that Itoh peonies had considerably stronger stems than typical peonies, which have top-heavy petals that flop.
She added, “They hold well on the stem. ” The Itoh peony made a superb cut flower, in my opinion. It makes a fantastic spring party favor when placed within a globular vase so that guests can see its beauty through the glass. You can extend those favors by getting gigantic blooms because they don’t all bloom at once. It’s undoubtedly an icebreaker at parties. The hostess present from the previous year continues to draw compliments. Nobody forgets the lovely flower in the vase, but my guests seem to forget the expensive bottle of wine.
Will peony thrive in Southern California’s temperate climate? That verdict may still be up for debate, but to peony growers Kathleen and Katharine, it is undeniably true.
Finding an Itoh peony can be your first challenge if you decide to do the peony challenge. Fortunately, a few southern California nurseries will have a very small quantity of these peonies accessible during the upcoming few weeks.
My roses appear to have black spots, I believe. What should I do or should I spray something?
In much of the nation, blackspot is a serious fungal rose disease; however, in most of Southern California, it is typically a minor issue.
However, we are experiencing a lot more blackspot than usual as a result of our unusually late rains over the previous two years.
I have two pieces of advice: if the issue isn’t too serious, don’t take any action. It should go away on its own when the weather gets warmer and dryer.
However, if the issue becomes too severe, you can use an organic fungicide like Rose Defense. You’ll probably need to use it every seven days for a few weeks until you see results.
Can you grow peony in Southern California?
Gardens in Southern California are ideal for Keiko peonies. Itoh peony Takara, which blooms in warm areas, is a deep rose variety. If you enjoy peaches, the Misaka peony, an Itoh hybrid suited to warm areas, can satisfy your craving. Gardens in Southern California are ideal for Keiko peonies.
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!
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.
In zone 10a, can peony be grown?
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.
Should peony be planted next to your home?
Is it true that ants are required to open peonies, or is this just an urban legend? Does anyone have a firm response to this? There is a lot of debate on the internet.
According to my own observations, you do require the ants to open the bud, at least until a few petals are visible. Ants are drawn to peony whether or not they are required. So I advise setting your peonies outside of the building. You will get an infestation if your plants are too close together. Not that I have any firsthand knowledge or anything…
Peonies aren’t particularly appealing to deer and rabbits, since we’re on the subject of animals. If those pests are a concern for you, plant without worrying about them getting devoured.
Best places to grow peonies?
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.
- Although it’s certainly possible to plant peonies in the spring, spring-planted peonies just don’t do as well. 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
