Itoh peonies for sale

Paeonia ‘Garden Treasure’ (Itoh Peony)

Considered to be the finest yellow intersectional hybrid by many gardeners, multiple award-winner Itoh Peony ‘Garden Treasure’ features very large golden yellow, semi-double flowers packed with 20-50 petals delicately flushed scarlet at their heart. Borne in profusion (expect 4 to 5 dozen of blossoms on a mature bush!), they are well presented above the foliage, on strong, erect stems that do not require staking. This late midseason peony will flower in late spring – early summer for 2 weeks (up to 4 weeks in cool weather areas) thanks to the many side buds which open in sequence. As a bonus, this Itoh peony is fragrant with a lovely lemon scent!

  • ‘Garden Treasure’ makes excellent cut flowers with a long vase life (over a week) if cut in bud. Enjoy a magnificent bouquet of yellow peonies at home!
  • Recipient of the prestigious American Peony Society Certificate of Merit (1984); Court of Honor, Grand Champion and Gold Medal (1996)
  • Reliable and vigorous, this Itoh peony grows in a compact but widely spreading bush of glossy, dark green foliage. Reaches up to 24-30 in. in height (60-75 cm) and up to 5 ft. in spread (150 cm). The foliage remains attractive throughout summer until late fall.
  • Enjoys full sun or part shade in rich, fertile, medium moisture, well-drained soils. Peony plants grow best in full sun but will tolerate some light afternoon shade. Provide a sheltered location. Staking may be required as the large peony flowers tend to arch toward the ground and may be driven to the ground by hard rain.
  • Deer and rabbit resistant but attractive to butterflies!
  • Virtually pest free. Watch for honey fungus and peony wilt.
  • Very useful and adaptable in the garden. Perfect as a specimen plant and in groups for borders and beds, city gardens or cottage gardens. Ideal for bordering a walk or driveway and as an informal hedge. Plant your peonies away from trees or shrubs as peonies don’t like to compete for food and moisture. The enchanting peony flower combines beautifully with roses, bearded irises and other perennials in striking color combinations.
  • Low maintenance. Remove spent flowers as they fade, then cut back plant after the foliage has died down in fall. Long-lived (peonies may live up to 50 years!), the plants do not need to be divided and can be left undisturbed for years. Peonies do not respond well to transplanting, so choose your planting location carefully.
  • The best time to plant peonies is in early fall, so they will have time to become established in the soil before winter. They do not flower the first year of planting, and may take up to two years to produce their showy, fragrant blooms.
  • All parts of the plant may cause stomach discomfort if consumed.

Itoh Peonies are hybrids produced by crossing a tree peony with an herbaceous peony. These peonies produce up to 50 or more huge flowers on sturdy short stems that do not require staking. They generally bloom after the herbaceous peonies for 3-4 weeks. Excellent as cut flowers, they are valued for their terrific array of yellow and gold colors, which are not widely available in herbaceous peonies. These plants have the lovely leaf form of the tree peonies, but die to the ground in the winter like herbaceous peonies. Strong and healthy, with a nice rounded bush form, they are typically shorter than most bush peonies. Growing up to 2.5 ft. (75 cm) tall by about 3 ft. wide (90 cm), their compact form and lovely shape allow them to be placed at the front of the border.

Peony Copper Kettle ~ Itoh Hybrid

Peony Copper Kettle is a Paeonia Intersectional or Itoh Hybrid. Intersectional hybrid Peonies also known as Itoh hybrids, named in honor of Toichi Itoh, the originator of these unique hybrid peonies. They are representative of the progeny of crossing or hybridizing the two main groups or selections of peonies; the herbaceous hybrids which die down sub surface buds during their dormant season and the tree or woody shrub peonies which retain a year round woody branch structure above ground level. During their dormant season, the Itoh or Intersectional hybrids retain only extremely short (1″-2″) woody stems above ground level. Ornamentally, they achieve the best of both parental worlds with the handsome flowers and foliage of the woody tree peonies displayed on an herbaceous plant, with annual new growth originating from buds below ground level. Strong healthy plants form attractive dense, neat rounded bushes which are shorter in stature than most tree peonies. Flowers are displayed above the handsome foliage that remains greener longer than their herbaceous parents. Intersectional hybrids are somewhat hardier than tree peonies and more tolerant of heat and humidity which extends their ornamental potential in both the North and south.

About Copper Kettle peony plants

The fall season is really the correct period regarding growing a peony plant. The peony plants tend to be exceptionally long-term-lived plants beeing alive up to 50 to a maximum of 70 years, so shortly after a person have the particular peonies planted in the right way, you is going to get pleasure from the plants for years and years. Peonies prefer the bright location with a well-drained dirt. A high quality air flow circulation presented around the plant is also important and vital. These kind of milieu assist peonies prevent disease issues. To organize a sowing hole meant for a bareroot peony, dig the soil into a depth of 12-18inches. Make use of garden tools to remove the edges of the seeding hole at the same time. It’s actually especially essential that the “eyes”, or growth, nodes, positioned nearby the base of the old stem, end up no greater than 2 inch under the soil surface.

Like ‘Keiko’ (see post here), ‘Kopper Kettle’ is another intersectional or Itoh hybrid peony. These plants have large flowers held up on strong stems like their tree peony parents, but their foliage dies back to the ground each winter.

My plant was purchased last spring without any flowers, and it gave three blooms this spring. At first I thought there’d just be one, but two more buds were hiding under the foliage.

You can see the interesting color combination of peach, rose, copper and cream that gives this flower its name.

While visiting my local nursery a couple of weeks ago, I heard the owner mention that they would no longer be carrying ‘Kopper Kettle’, since it has proven to be less vigorous than hoped. He said Monrovia will be introducing a newer Itoh with similar coloring called ‘Picasso’ or ‘Picassa’.

So here’s another lesson on the virtue of patience – it’s always wise to wait a few years to see how a new introduction does before buying it for your own garden. But us gardeners (ahem) sometimes have more enthusiasm than wisdom.

I’m certainly not ready to rip out this plant and replace it with another expensive Itoh hybrid. I’ll just give it some bloom booster fertilizer and enjoy the flowers it puts out, even if there aren’t as many of them as one would like. In the photo above you can see how the color has faded after several days in the sun.

This photo shows one of the blooms that showed up under the foliage. Its coloring is especially vivid since it didn’t receive any direct sun.

I cut the flower and enjoyed it inside for several days. The color didn’t fade, and the bloom put out a spicy fragrance. When ‘Keiko’ was blooming (it bloomed earlier since it had been in a greenhouse all winter), I cut a bunch of flowers and was impressed with how well they held up in a vase (see below). Their color holds up much better inside, so in future springs I’ll probably cut most of the flowers from my Itohs for vases and show them off indoors.
Recently I have also been researching tree peonies and have decided to try a few in my yard. I placed an order from Cricket Hill Gardens for a couple of red-flowering tree peonies to arrive this fall. I was very impressed with the gorgeous photos of both tree and herbaceous peonies at the Peony’s Envy website – check it out if you have time to enjoy some vibrant, luscious flower images.
ADDED May 2012 – ‘Kopper Kettle’ has 20 buds right now, which is nothing to complain about! ‘Keiko’ has fewer than last year, maybe 10 total. One long-time grower of intersectionals suggested that these plants can be inconsistent with their flowering while young. They live for a long time, though, so there’s plenty of time ahead for more flowers.

Itoh Peony Types – Tips On Growing Hybrid Peonies In The Garden

Peonies are popular garden plants with both herbaceous and tree peonies available. But there’s also another peony you can grow – hybrid peonies. Continue reading to learn more about Itoh peony types and growing hybrid peonies.

What are Itoh Peonies?

In the early 1900’s, plant breeders scoffed at the idea of cross breeding herbaceous peonies with tree peonies; the species were considered too different and incompatible. In 1948, after thousands of failed attempts, Japanese horticulturist, Dr. Toichi Itoh, successfully created seven peony hybrids from a tree peony bred with an herbaceous peony. These were the first Itoh peonies. Sadly, Dr. Itoh passed away before ever seeing his creations bloom. Years later, American horticulturist, Louis Smirnow bought some of these original Itoh peonies from Dr. Itoh’s widow and continued Itoh’s work.

Itoh Peony Types

After Smirnow brought Itoh peonies to the United States, other plant breeders began to

hybridize new varieties of Itoh peonies. These rare early Itoh peonies sold for anywhere between $500 and $1,000. Today, many nurseries grow Itoh peonies on a much larger scale, so they come in many varieties and are much more affordable.

Some available varieties of Itoh peonies are:

  • Bartzella
  • Cora Louise
  • First Arrival
  • Garden Treasure
  • Yankee Doodle Dandy
  • Keiko
  • Yumi
  • Kopper Kettle
  • Takara
  • Misaka
  • Magical Mystery Tour
  • Hillary
  • Julia Rose
  • Lafayette Escadrille
  • Love Affair
  • Morning Lilac
  • New Millennium
  • Pastel Splendor
  • Prairie Charm
  • White Emperor

Growing Hybrid Peonies

Also called intersectional peonies, Itoh peonies share qualities with both parent plants, tree and herbaceous peonies. Like tree peonies, they have large, long lasting blooms and strong stems that do not require staking. They also have dark green, lush, deeply lobed foliage that lasts until autumn.

While the foliage grows dense and healthy in full sun, the flowers will last longer if they get some light shade. Itohs are prolific bloomers and get a second set of blooms. They also can grow vigorously to 3 foot tall and 4 foot wide. Itoh peonies are also resistant to peony blight.

Plant Itoh peonies in full sun to part shade and in rich, well-drained soil. Itoh peonies are sensitive to high levels of nitrogen. When fertilizing in spring and summer, be sure to use a fertilizer that contains a low level of nitrogen, like 4-10-12. Do not fertilize peonies in late summer to fall.

Itohs can be deadheaded as needed throughout the spring and summer. In autumn, cut back Itoh peonies to about 4-6 inches up from the soil level. Like herbaceous peonies, Itoh peonies will come back in spring from the ground. In fall, you can also divide Itoh peonies just as you would divide herbaceous peonies.

The Difference between Herbaceous Peonies and Itoh Hybrid Peonies

Herbaceous Peonies vs Itoh Hybrid Peonies

The plant world is always developing new and exciting cultivars and hybrids of plants. It is hard for me to keep up on all of the new developments in the plant world, but when I do learn about a new group or type of plant it is very exciting. I will admit I was not up to date on the newest hybrids of peonies, which are the Itoh Hybrid Peonies. In spring of 2018 when Tulip World started selling Scrumdiddlyumptious Peonies I quickly learned about this amazing new type of peony. Itoh hybrid peonies have a lot of strong qualities; however, traditional herbaceous peonies have tremendous value and qualities as well. For some gardeners the traditional herbaceous peonies will be what is needed to enhance our gardens, for others, Itoh hybrid peonies will work better. If you are lucky you will have room for both herbaceous peonies and Itoh hybrid peonies. If you aren’t sure which peony to plant, continue reading for more information on the differences between herbaceous and Itoh hybrid peonies.

Herbaceous Peonies

Let’s start with the classic spring blooming favorite, herbaceous peonies. With their large blooms that are often fragrant, it is common to see peony plants that have been in the same location for 75 or more years. First, they are called herbaceous peonies because their leaves and stems are herbaceous meaning they die back to the ground in the winter months, as opposed to a tree peony that has woody stems which remain present during dormancy. Herbaceous varieties of peonies grow in hardiness zones 3-8. Similar to certain fall planted bulbs and lilac bushes, herbaceous peonies require cold temperatures in order to produce blooms. Therefore, herbaceous peonies are best suited to gardeners in northern and central states where the temperatures are most favorable for the conditions they require. Herbaceous peonies will start blooming in late April through mid-June depending on the cultivar, location, and weather in that location. Like most plants, different cultivars of peonies will bloom at different times during their approximate bloom season. Herbaceous peonies typically reach a maximum height of 2-3’ with a similar spread, making them a great perennial for the back of a perennial border. Herbaceous peonies are fairly prevalent and available, making them an affordable perennial option for your garden. Herbaceous peonies bring great feelings of nostalgia as these long-lived perennials may have been at your grandparents or parents’ house when you were a child, and they are still there decades later. If you have a sunny location and 2-3’ of extra space you want to fill in with some spring color an herbaceous peony may be what you are looking for.

There are two complaints I often hear from people about herbaceous peonies. The first complaint is that peonies attract ants, which is true. It is very common to see ants on peony blooms in your garden and even in vases when you cut the blooms. However, the ants are gathering nectar from the blooms and are not harmful to plants or humans. Therefore a few common ants shouldn’t deter you from enjoying the beautiful and fragrant blooms that peonies provide. The second complaint about peonies is that after heavy rain the blooms and stems often droop making the plant have a bit of a messy appearance. The rain can certainly cause your peonies to lose their nice appearance; however, you may use stakes or tomato cages to hold up the blooms. While this will require extra work initially, being able to enjoy the blooms for many years is well worth it.

Itoh Hybrid Peonies

The new kids in the garden are the Itoh hybrid peonies. Itoh peonies are a cross between herbaceous peonies and tree peonies. First developed by Japanese horticulturalist, Toichi Itoh in the 1960s, it took decades for these hybrid peonies to become available for the mass public. These flowers are also referred to as intersectional peonies, since they are crossed between herbaceous and tree peonies. Itoh peonies are becoming more prevalent in nurseries and online retailers; they are a bit more due to their tremendous qualities.

Itoh peonies have many of the same qualities as herbaceous peonies like large, showy and more often than not fragrant blooms. Like herbaceous peonies, these Itoh hybrid peonies go dormant during the winter months, where the leaves and stems will die back to the ground. The characteristics Itoh peonies get from their other parent the tree peony include their sturdy stems which prevent them from being droopy after heavy rain. Itoh hybrid peonies also bloom later in the season and typically are starting to bloom when the herbaceous peonies are finishing their blooms for the season. The bloom time of Itoh hybrid peonies is also a bit longer than that of herbaceous peonies. Growing 2-3’ tall with a similar spread, Itoh peonies will take up about the same amount of space in your garden as herbaceous peonies. The color ranges I have noticed in the Itoh hybrid peonies are stunning and full of dimension. Varieties like Hillary Itoh Hybrid Peony have coral, peach, pink and orange tones throughout. Scarlet Heaven Itoh Hybrid peonies have large 6” across single blooms in deep true red. Cora Louise Itoh Hybrid Peony has pale pink single blooms with a bright pink center, they are showy and slightly fragrant. With many colors to choose from and a later, longer bloom time it is no wonder Itoh peonies are taking the gardening world by storm!

A Peony for Every Garden!

Peonies can be purchased as potted plants at nurseries and can also be purchased as bare roots for planting. Online retailers like Holland Bulb Farms and Tulip World sell peonies as a bare root for planting in fall as well as spring. For spring planting of bare root peonies, expect growth to appear that summer, but you most likely won’t see any blooms until the following spring. Since peonies are long-lived perennials up to 75 years or more, no need to worry if you have to wait a year or 2 for blooms, they will be around a long time.

Both herbaceous and Itoh hybrid peonies have a place and use in any sunny garden bed or border. The main differences between the two are the sturdiness of the stems, bloom colors and bloom times. Herbaceous peonies bloom earlier in the season whereas the Itoh hybrids bloom a bit later in spring and tend to have a longer bloom time. If you really love peonies and have space for them my suggestion is to plant both herbaceous and Itoh hybrids to maximize bloom time. Herbaceous peonies are most commonly seen in shades of pink, red, white, yellow and peach. Itoh hybrids are available in shades of those colors as well, but the variance of colors seen in the blooms is greater than that of herbaceous peonies, which tend to be more solid colors. Planting both Itoh hybrids and herbaceous peonies will have you reaping the rewards of their colorful, fragrant blooms for many weeks every spring for years to come.

Peonia ‘Pastel Splendor’

Itoh Hybrid Peony

USDA Zone: 3-9

Plant number: 1.900.590

Itoh Peonies are rare and unusual hybrids between Garden Peonies and Tree Peonies. There are several varieties, all highly sought after by collectors, yet are easy to grow and very hardy. This selection forms a midsized upright bush of lush green leaves. Very large flowers emerge pastel, creamy-yellow with prominent dark maroon blotches in the centre. As the flowers mature, light pink appears from the petal tips toward the centre. Peonies seldom need to be divided or moved, but if necessary it should be carried out only in the fall. Flowering is always best in a sunny location. Clean up the dead leaves in the fall to help prevent disease problems. Plants usually die to the ground, or to very low woody stems in the winter. Flowers on cut stems have a short life which makes them less suitable in arrangements. A better alternative for indoor display, cut about an inch below a bloom and float in a rose bowl.

About growing Bartzella a peony

The fall is really the correct period of time for planting a peony. These peonies have proven to be incredibly long-term-lived plants beeing alive approximately 50 up to 70 yrs, so once a person get the particular peonies placed in the right way, you is going to get pleasure from the plants for many years. Peonies have a preference for some sort of sun-drenched place with a well-drained dirt. A high quality air movement available the peonie can also be significant. These kinds of conditions assist these plants to stay away from illness problems. To organize the seeding hole meant for a bareroot peony, dig the ground into a depth of 12-18″. Use garden tools to loosen the sides of the seeding hole as well. It really is extremely critical that the “eyes”, or growth nodes, located close to the bottom of the old stem, end up no greater than Two inches under the soil surface.

Bartzella Itoh Peony

Planting Peonies

Adding peonies to your garden is easy. Plant in full sun in most regions. In colder regions, planting peonies in shade will result in weak stems and less flowers. In warmer regions or where spring is hot and dry, choose a site with afternoon shade. Plant in average or well-draining loamy soil. Peonies prefer soil that provide moisture, but isn’t water logged. Add compost if needed before planting.

Planting Steps for Herbaceous and Intersectional (Itoh) Peonies

  1. Choose a site with well-drained soil away from any competing roots. Peonies thrive if left to grow undisturbed in the same location for years.
  2. Dig a hole 12″ wide and the length of the roots. This is the time to add any compost in the bottom of the hole. Plant the roots 1″ to 2″ below the soil level with the eyes (buds) pointing up. If you are planting more than one, plant 2-3 feet apart to allow enough space. If planted too deep, the peony will lack blossoms. Visit our planting guide for a detailed description
  3. Slowly back-fill around the roots, not allowing any air pockets, adding pressure to compact the soil.
  4. Once planted, gently water around the plant. Add a light mulch or chopped leaves to reduce weeds and to regulate soil temperature and moisture. Water every day for 5 days in the morning or evening, unless it rains or there is lots of moisture. Be sure not to over water, as the roots will rot.

Planting Tree Peonies

Planting tree peonies is different than herbaceous and intersectional itoh peonies.

  1. Choose a site with well-drained soil away from any competing roots. Tree peonies thrive if left to grow undisturbed in the same location for years.
  2. Dig a hole the length of the roots roughly 2 feet deep and dig it wide enough to accommodate the roots with some room to grow, roughly 1 foot wide. This is the time to add any compost in the bottom of the hole. If you are planting more than one, plant 2-3 feet apart to allow enough space.
  3. Slowly back-fill around the roots, not allowing any air pockets, adding pressure to compact the soil.
  4. Once planted, gently water around the plant. Water when needed, the best practice is when the soil has dried out and or it hasn’t rained. Tree peonies need water to generate root growth, but if over watered, they will rot.

Aftercare

The first year of growing peonies, expect the roots to products 2-5 leave shoots and 1-2 flowers. Year two brings a plant double the size and double the blossoms. By the fourth or fifth year peonies will be full and bushy, with lots of foliage and blossoms.

Staking

Itoh and tree peonies don’t require staking, but most herbaceous peony once established, produce heavy flowers that often are too heavy for its stems. You don’t have to stake them, but if you don’t, you’re going to have big beautiful flowers nodding down. So once you have a healthy clump, use peony rings to keep them upright. The rings are simply wheel-like wire arrangements that stand up over the peony like a little wire table as the plant sprouts in the spring. With upright supports, the peony ring is placed so the shoots will grow up through the round wire bale. Of course, the foliage quickly hides the ring, and you have a beautifully-supported clump well before the flowers open. Where to find Peony Rings? We recommend Gardeners Supply.

Pruning/Trimming

For herbaceous and (itoh) intersectional peonies after blooms have passed, clip expired blooms down to the where the foliage meets the stem. Leave the foliage for the remainder of the growing season. As fall arrive and temperatures cool, the leaves will turn yellow and then wilt. For herbaceous peonies trim back all foliage to about 3″ from the ground. This keeps the plant tidy and allows new growth to come up without damaging it. In the fall itoh peonies need to be treated similar to herbaceous and tree peonies since they are a hybrid of both. Once the plant has matured its best to trim back so that the herbaceous portion of the stem is removed and the hard wood portion remains. Its best to leave the peonies alone in there first year of growing so that you tell the difference between the herbaceous green stem from the hard wood portion as the leaves die back. Usually mature itoh peonies will leave 4-5 inches of hard wood above ground.

Tree peonies require different trimming techniques. Cut the stem just below the expired blooms. If you trim the stem to far, it will hinder next year’s growth. This years green shoots will become next years woody branch. So in the fall, do not trim back or cut to the ground, leave the shrub as is. If you have a mature tree peony and it needs shaping, the best time to prune, is right after it blooms. Make sure to not take to much off the tree as it can really hurt the shrub.

Fertilizer

Peonies don’t need to be fertilized every year. Its best to plant them with plenty of nutrients. Apply bonemeal, compost or well-rotted manure in early summer, after peonies have bloomed every couple of years.

Paeonia ‘Bartzella’

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun or partial shade
  • Soil: fertile, moisture-retentive yet well-drained
  • Rate of growth: average
  • Flowering period: June to July
  • Hardiness: fully hardy
    Possibly one of the most popular of all the intersectional peonies, which are a cross between the herbaceous and the tree forms. It has inherited the best qualities of both its parents, so has large, deeply cupped bright yellow flowers over a relatively long period. They appear against a backdrop of lustrous green foliage, which forms a bushy mound, and takes on autumnal tones before it drops in autumn. It’s perfect for adding an exotic-looking shot of early summer colour to the border, and shows a good resistance to diseases.
    This paeonia has been field grown, however in order to keep the roots hydrated and promote fresh new growth, we have potted them up. Therefore, your plant may not have a well developed root system just yet, so you should not worry if the soil falls away when you are planting it out.
  • Garden care: Plant so the crown is around an inch or so below ground level. In early spring apply a top dressing of a balanced, slow release fertiliser around the base of the plant and mulch with well-rotted compost or manure. Cut the woody stems back in autumn or spring.
