One of the today’s most widely grown hardy perennials is the herbaceous peony. A peony has a long lifespan and is tough; it can easily live for more than 100 years.
This particular group of peony is a herbaceous perennial that grows stems every year in the spring and summer before dying to the ground in the late fall and remaining dormant all winter long. Each spring, the thick, fleshy root systems, crowns, and buds come to life once more to produce the beautiful flowers we have come to love.
In order to fulfill their requirements for dormancy, all herbaceous peony require a period of cooling. While the majority can usually be grown in USDA Hardiness Zones 3 through 7, some gardeners have had success as far south as zone 8.
The most popular herbaceous peony cultivars in gardens are Paeonia lactiflora varieties, which have “rooted” origins in China. They are frequently referred to as the Chinese Peony, a term that is still widely used in the industry today. In general, Lactiflora varieties make excellent cut flowers and frequently have lovely fragrances.
More recently, hybridizers of peonies started mating different species together to produce hybrid peonies. The hybrids have a wide range of flower and plant traits, making them suitable for more varied application in gardens and landscapes. P. lactiflora and the hybrids are both grown in the same manner and have comparable cultural requirements and plant behaviors.
How can I tell if my peony is a herbaceous variety?
White, cream, pink, yellow, and red flowers with a single or double bowl form are found on herbaceous peonies. The flowers are either more open or loosely packed with petals, although they frequently have a spicy aroma.
Are perennial herbaceous peonies?
Depending on the variety, herbaceous peonies bloom in early to mid-spring and are extremely hardy perennials (USDA zones 3-8). Stems die back to the ground in the fall. The best development occurs in a region with rich, well-drained soil and direct sunlight. For detailed information on cultivating herbaceous peony, see our Learn section.
In Asia and Europe, herbaceous peony come in more than two dozen different wild kinds. The most prevalent species is Paeonia lactiflora, also known as asshaoyao in China, where it is endemic. Large-flowered, fragrant cultivars were imported from China in the early 1800s and planted for decorative purposes in Europe. Many of these were eventually imported to America and are now regarded as heirloom cultivars. Some of these venerable favorites can be found in our collection, along with more modern hybrids that open their blooms earlier than the conventional kinds, extending the season of herbaceous peonies.
What distinguishes herbaceous from tree peonies?
Perennial peonies called herbaceous peonies fade back to the ground every year. The plant stems push up in the spring while the roots remain dormant beneath the dirt. Woody, deciduous shrub peonies are called tree peony. They shed their foliage in the fall, but unlike herbaceous peony, their woody branches do not die back to the ground. Itoh peonies are a hybrid cross between herbaceous and tree peonies; while they do die down to the ground in the fall like herbaceous peonies, they exhibit tree peony-like growth and flowering traits.
Before they became beloved ornamentals, tree peony, which are native to China, were prized as a therapeutic plant. A tree peony can reach a height and width of up to five feet (1.5 meters) in around ten years and is a larger, woodier relative of the ordinary herbaceous peony. They are widely coveted for their huge, prodigious blooms, which can reach a diameter of up to 10 inches (25+ cm).
These blooms occur in single or double shapes and bloom from late spring to early summer. They are great cut flowers. Tree peony do not produce the sweet honeydew sap that herbaceous peonies do, which is what draws ants to their flower buds.
What three varieties of peony exist?
About 30 species of flowering plants in the family Paeoniaceae make up the genus peony (genus Paeonia), which is distinguished by its enormous, spectacular flowers. The majority of these species are produced as ornamentals and for the flower industry, with the exception of two that are native to Europe and Asia.
Peonies can be divided into three different types: herbaceous Eurasian peonies, Asian tree peonies, often known as moutan peonies, and North American peonies. The perennial herbaceous peonies can reach heights of approximately one meter (about 3 feet). They feature broad, glossy leaves with numerous divisions that grow on annual stems made by fleshy rootstocks. They produce enormous single and double flowers in the colors of white, pink, rose, and deep crimson throughout the late spring and early summer. The majority of the well-known garden peonies are descendants of the fragrant Chinese peony (P. lactiflora) and the European common peony (P. officinalis). P. lactiflora has produced hundreds of cultivated varieties, including Japanese forms with a cluster of partially developed petals in the center and one or two rows of petals on either side (petaloid stamens).
How big can you grow herbaceous peonies?
The stately peony (Paeonia sp. ), which boasts sumptuous flowers starting in late spring, is unparalleled in gardens and bouquets. These fragrant flowers are simple to grow, providing you live in a cold-winter area, and come in a stunning spectrum ranging from white through pink to red and mauve, as well as ruffled single and double forms.
Where the climate isn’t chilly enough, you can plant a tree peony, which is just as exquisite, to enjoy the beauty of this blossom. Both have a lengthy lifespan, with blossoms become more beautiful with age.
How do I grow peonies?
Herbaceous peonies can only be found in mountainous regions, such as Tasmania, Victoria, and places with cold winters. Cold helps to stimulate the growth of the flower bud. Although they can also grow in cool temperate regions, tree peonies prefer cold weather.
Herbaceous and tree peonies should be planted in full light and protected from severe winds. A site that is only slightly shaded is preferable in regions with scorching summers.
Plant in soil that is rich in well-rotted compost and manure that is deep, wet, and well-drained. Herbaceous peonies like a neutral soil pH, whereas tree peonies prefer a more alkaline soil, so before planting, add dolomite lime and fork it in thoroughly.
Never let the soil become damp. Water soil in the summer to keep it cool and prevent drying out. Tree peony are quite drought tolerant after they are established (12 years), but they benefit from frequent irrigation throughout the growing and flowering season.
Herbaceous peonies should be fertilized in the late winter, and any surrounding weeds should be pulled. In the summer, after deadheading and the peonies have stopped blooming, reapply fertilizer. Feed tree peony in the winter and late spring with a fertilizer that is heavy in phosphorus and potassium but low in nitrogen. This will support healthy root development and flowering.
Peonies can be transplanted, but in general, they don’t like to be disturbed, so be careful where you put them. One week before planting, prepare the soil by adding well-rotted compost, manure, and dolomite lime (if necessary).
Types of peony
Herbaceous peonies are best planted in the fall and are sold as bare root rhizomes with a few buds or “eyes.” Dig a hole that is no deeper than 5 cm, and then harden the hole’s foundation. Rhizomes should be placed with the buds facing up. The soil should then be backfilled, softly firmed, and properly watered. Plants should be at least 60 cm apart because they want some room between them.
This perennial grows slowly but finally develops into a big shrub that is 90H by 50CmW in size. In the winter, the stems retract.
In containers, tree peonies are sold. Make a hole that is slightly deeper and twice as wide as the pot. Plant should be taken out of pot, roots carefully teased out, and placed in hole. Refill and thoroughly water.
Because of its numerous stems, it is more like a shrub than a tree. The tree peony has a large visual impact and can reach heights of over 2 meters. Plant it in your garden as a specimen to give it space to spread and an unobstructed view of its blossoms.
Use a three-legged metal wire frame to support the stems as herbaceous peonies grow. Visit your neighborhood garden center to find them. The plant is still developing and won’t flower until it becomes a strong bush, so don’t be shocked if there are few or no flowers in the first year. Allow the foliage to naturally die down in the late fall before pruning. Long stems from the bush’s blooms can be trimmed for indoor display, and deadheading frequently as the petals fade will encourage additional blooms.
Tree peony should only be pruned once the growing season begins in order to remove any dead or broken branches. Every three years, thoroughly hydrate the soil after adding a sizable amount of dolomite lime.
The enormous blossoms, a hybrid of the herbaceous and tree peony, bloom for a longer time. It has tree peony leaves, yet in the winter it dies back to the ground like a herbaceous peony. Its petals frequently have two colors.
How to grow herbaceous peonies
With a little tender loving care in the peony’s early years, you can enjoy watching it bloom for up to 80 to 100 years.
Start with bare roots in the fall because the roots don’t like to be disturbed. Create a soil mound at the bottom of the 60 x 60 cm pit, 2-4 cm below the garden’s surface. Place the eyes, or buds, facing up on the mound. Backfill, gently compact the dirt, and add water. Soak the roots overnight if they appear dry.
An open north or east location that receives morning spring sun and full summer sun will aid in the development and emergence of buds into blooms. Defend against high winds.
Alkaline, nutrient-rich, and well-drained Before planting, if necessary, dig in organic matter.
They need a lot of water in the summer but dislike having their feet wet, so if your soil can’t drain the water, try growing your plants in a raised bed or a big container. Although they grow somewhat drought tolerant as they get older, they still require constant watering during their first summer and throughout extended, hot, dry spells.
Avoid fertilizing in the spring to avoid burning the new growth. Give a balanced meal instead in the late winter and summer when the flowers have faded.
Cut back any lingering stems in winter when they naturally retract so that they can reappear in April.
Herbaceous vs tree peony
The most widely cultivated peonies are herbaceous peonies, usually referred to as Chinese peonies (Paeonia lactiflora). They emerge from rhizomes and grow into a 1 m tall bush that blooms in the late spring and early summer before withering in the autumn. The tree peony (Paeonia suffruticosa) is a deciduous shrub that reaches a height of about 1 m. They do not die down like their herbaceous cousins and can take up to 10 years to reach their peak height. Peonies of both varieties favor chilly to cold temperatures.
Types of blooms
This flower has a single row of petals encircling a dense circle of stamens, making it simple and attractive.
These peony blossoms are the most well-liked in Australia due to their several rows of voluminous, ruffled petals.
Similar to doubles, but still distinguishable and still present at the center after the bloom has faded.
How long are the blooms on herbaceous peonies?
Peony species include the following:
- Peony tree (Paeonia suffruticosa)
- Paeonia lactiflora, sometimes known as the Chinese or herbaceous peony
- The name “herbaceous peony” typically refers to the woodland peony (Paeonia japonica), which is likewise a herbaceous species but distinct from the common garden peony.
- Intersectional (the Itoh hybrid)
Early in the spring, forest peonies are the first to blossom. The tree peonies arrive a week after they do. The herbaceous peony start to bloom a week or two later. Planting cultivars that bloom at various times—early, midseason, and late—can extend the bloom season even though the flowers themselves only last seven to ten days. The blossoms can last for another four to six weeks in this fashion.
Near the conclusion of the herbaceous variety’ blooming period, the intersectional peonies, which are a hybrid cross between tree and herbaceous peonies, begin to flower. On intersectionals, the buds don’t all open at once, so they can continue to bloom for up to three weeks.
Planning your garden should take into account the fact that peonies are difficult to transport and adapt to new environments. They won’t bloom again for another two to three years if you do decide to move them.
In conclusion, you can enjoy peonies flowering for eight weeks or longer if you have all four species in your garden: forest, tree, herbaceous, and intersectional.
How are herbaceous peonies cared for?
6. Herbaceous Peony Typical Care
- SPRING. Pay attention to spring frosts. Peonies should be staked. Feed as new shoots appear. Optional: Deadhead after the bloom.
- SUMMER. Feed Following Bloom. Water During Drought Conditions. Around Peonies, Weed
- FALL. Water During Drought Conditions. Your herbaceous peonies should be pruned. Before winter, feed.
Where would be the ideal location to plant 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.
- 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
