I didn’t factor in record-breaking heat when I chose to write about one of Utah’s biggest and most impressive spring blooms.
You could discover that some of these flowers have already concluded their display in warmer regions since they typically bloom around Memorial Day.
Peonies are hardy perennials that require little maintenance and do well across the state. The leaves make a good background for smaller plants, and the huge, brilliant blossoms make superb cut flowers.
Plants require little maintenance once they are established. They are able to endure years of growth in one place. They consistently blossom each spring (usually in May or early June).
The garden or herbaceous types are featured in this column and have broad, bushy stems that reach heights of 2 to 4 feet.
On woody stems, tree peony can reach heights of 5 to 6 feet. They cost more and are less frequently grown in Utah. They grow a shrub-like plant with several flowers on it. Tree peony’ stems do not wither away in the winter.
The Itohor intersectional hybrids, which are hybrids of herbaceous and tree peony, are the newest subgroup. They can reach a height of 3 1/2 feet, blooming for a longer period of time than typical herbaceous varieties, and the flowers are better supported by the stronger stems.
Garden peonies are divided into five categories based on the design of their petals.
Single, semi-double, double, Japanese, and anemone are among them. There are numerous varieties of each category. Approximately 8,000 identified cultivars of peony are listed by the American Peony Society. Yellow, cream, pink, rose, or deep crimson are the colors of flowers. In Utah, double peonies are most prevalent.
Tuberous roots or underground stems that store nourishment are the source of peonies. On the tuber, new development appears as buds or eyes. Even though a single tuberous root may contain numerous eyes, the plant cannot thrive without at least three buds.
The highest eye of the tuberous roots should be planted one inch beneath the soil’s surface. Deeper planting is frequently to blame for the plants’ inability to blossom.
Bright red can be seen on the juvenile spring shoots. They are easily harmed, so keep pets and foot traffic away from them. The mature leaves are glossy and dark green.
If given the right care, peonies grown in containers can be planted at any time. Because the roots decay in damp soil, peonies require well-drained soil. Because peonies can remain in one spot for many years without being divided or transplanted, carefully select the growth location and prepare the beds.
Peonies do best in full light. Avoid planting them beneath trees or bushes because their roots will fight with them for water and nutrients and because they are poor competitors. To keep flower stems from breaking in high winds, plants must be protected.
The plants are deprived of water, nutrients, light, and space by weeds. Carefully remove weeds so as not to disrupt peony roots. Keep turf grass away from the plants since grass is fiercely competitive.
Regular irrigation is required for peonies. Don’t let the soil become soggy. The soil should dry out in between waterings. Late-day sprinkles should be avoided since they promote fungal illnesses.
In rich garden soil, plants require less fertilizer. Apply fertilizer as needed during the growth season to boost blossom size. In Utah’s alkaline soils, iron chlorosis affects them adversely. The leaves don’t develop or bloom well, turning green with yellow veins. When symptoms emerge, avoid overwatering the plants and treat with iron chelate.
Staking the plants is occasionally necessary because when the huge blossoms form, the plants become top heavy. Plants should only be staked when necessary; never stake a plant in the middle as this could harm the tuberous roots.
Remove the petals after the blooms have dropped them to prevent the development of seeds. Keep the plant’s green leaves since it provides energy that will help it blossom nicely the following year.
When peonies are grown in Utah, the most common criticism is that they do not flower. Despite having sound roots and robust tops, they frequently fail to flower. When peonies are cultivated in excessive shadow, they do not bloom. Root development is hampered by poor drainage, which also stops flowers from flowering.
If eyes on tuberous roots are buried too deeply, peonies will not blossom. One inch or less of soil must be buried behind the eyes or buds.
Blossom formation is hampered if too much foliage is removed when cutting the blossoms or if the foliage is trimmed back before it dies back in the fall. Additionally, if other plants occupy the water, nutrients, light, and space that peonies require, they might not bloom. In the spring, late frosts can also destroy flower buds.
Few peony diseases exist in Utah, and the most are managed by careful watering; fungicides are only occasionally required.

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
How long are the peony in Utah in bloom?
Its stunning, frequently fragrant blossoms, which can be any color but blue, contrast with the plant’s aggressively textured foliage.
Paeonia hybrids, which are native to Asia and have been cultivated for their aesthetic displays for many years, are frequently categorized according to the sort of bloom they produce. Flowers come in a variety of forms, including single, japanese, anemone, semi-double, double, and bomb-double, which are all progressively more complicated. Each peony type blooms for one to two weeks in the spring, but by including kinds that bloom earlier or later in the season, you may easily lengthen the bloom time in your landscape.
By dividing them, peonies can be multiplied; just make sure that each piece has 3-5 buds.
Your young peony may require several years to become established before it starts to bloom, depending on the size of the start.
Despite the fact that peonies are grown from seeds, you should deadhead your peony to stop the formation of seeds. As a result, the root system can receive more energy, which will promote healthy growth the next year. Site selection is important for peony, but once they are established in the ideal location, they require very little maintenance and can bloom for years.
They have a fleshy root structure that thrives in rich, well-drained soils and can be vulnerable to root rot in an area that is heavy and poorly drained.
For the finest show, staking can be necessary because the flowers can be rather heavy and prone to lodge (flopping over) or stem breakage, particularly after rain.
To reduce this issue, look for cultivars with blooms that are near to the foliage or that have a more straightforward form.
Similar in appearance is the tree peony (Paeonia suffruticosa), but it has woody stems that cling to the ground. It is multiplied through grafting.
A garden peony and a tree peony are crossed to create an Itoh, also known as an intersectional hybrid, which was created by Toichi Itoh in Japan. Its foliage resembles that of a tree peony, however each year its stems fall off. Traditional peonies are lovely perennial spring flowers, but some gardeners are leery of them because of their limited blooming season and large blossoms.
An Itoh hybrid produces robust stems, good height, and a large number of colorful blooms.
These hybrids, which combine the greatest characteristics of both the daintier herbaceous and the big-flowered tree peonies, give the best of both worlds.
But what makes these hybrids so remarkable is that they produce several buds on each stalk.
As a result, you will enjoy a bloom that lasts for at least a month. Over the course of one season, a mature peony can produce 30 to 50 flowers!
What states produce peonies?
Peonies are vibrantly colored flowering plants that make wonderful additions to gardens. They are simple to cultivate and don’t need much maintenance to prosper.
These resilient perennial plants can withstand harsh winters, and some of them may even outlive people.
North of South Carolina and Texas is where the majority of peony are grown in the United States. The U.S. Department of Agriculture (USDA) adds that while certain kinds can grow further south, they rarely blossom because the winter temperatures are not cold enough for flower buds to properly mature.
Peonies come in many different types, but the two that are most frequently planted are garden (herbaceous) and tree peonies.
The typical garden peony can be found in many home gardens and comes in a range of bloom shapes.
Garden peonies come in five different varieties, each with a distinctive petal shape. Single, semi-double, double, Japanese, and anemone are among them.
On woody stems with sparse branches, tree peonies can reach eye height. The buds for the upcoming year’s growth are found on the stems, and they are maintained all year long.
