Peony ‘Karl Rosenfield,’ regarded by many gardeners as one of the best red double Peonies, is quite attractive. Late spring to early summer sees an abundance of large, rose-shaped, brilliant cherry-red, double flowers that can grow up to 6 inches wide (15 cm) carried above the lush foliage.
- This late midseason peony will bloom for about 7 to 10 days and is fragrant. To extend your peony season by up to 6 weeks, you might wish to plant several cultivars with different flowering times (there are early, mid, and late blooming kinds).
- If cut in bud, ‘Karl Rosenfield’ produces beautiful cut flowers with a lengthy vase life (over a week). At home, enjoy a stunning bouquet of red peonies!
- This robust and dependable herbaceous peony grows in a luxuriant, bushy mound with glossy, dark-green, split foliage that can reach heights of up to 24-36 inches (60-90 cm) and spreads out to a width of up to 24 inches (30 cm) (60-75 cm). Up until the first frost, the foliage is still lovely and frequently becomes a deep ruby red in the fall.
- like full sun or partial shade in healthy, rich soils with a medium moisture level and good drainage. Even though they thrive in full sun, peony plants can tolerate a little midday shadow. Provide a protected area. Due to their propensity to arch downward and their vulnerability to being knocked to the ground by heavy rain, huge peony blossoms may need to be staked.
- Deer and rabbit resistant, but butterflies like it!
- virtually free of pests. Watch out for peony wilt and honey fungus.
- incredibly practical and flexible in the landscape. Perfect for borders and beds, city gardens or country gardens, both individually and in groups as a specimen plant. Ideal for using as an informal hedge and to border a walk or driveway. Peonies don’t like to fight for food and moisture with trees or shrubs, so plant your peonies away from those plants. Roses, bearded irises, and other perennials make stunning color combinations with the alluring peony blossom.
- easy to maintain. Cut back the plant after the foliage has fallen back in the fall, then remove any faded or wasted flowers. Peonies have a long lifespan (up to 50 years! ), therefore the plants don’t need to be divided and can be left alone for a long time. Selecting the right planting place is important since peonies do not adapt well to transplanting.
- Early fall is the ideal time to plant peonies so that they have time to establish themselves in the ground before winter. Their gorgeous, fragrant blooms may not appear for up to two years after planting since they do not flower the first year.
- If swallowed, the plant could upset your stomach if any portion of it is consumed.
- harmful to horses, cats, dogs, and other animals.
Peonies have been grown for more than 2000 years and are a traditional component of perennial borders. Peony flowers give a brilliant burst of color to the late spring and early summer garden. They are prized for their profusion of blooms, the beauty of their magnificent flowers, their pleasant smell, and their robust foliage that changes shades with the seasons. One of nature’s most beautiful perennials, they are practically careless once established, produce some of the nicest cut flowers, are deer resistant, and survive for years. Both florists and many upcoming brides have a soft spot for peony bouquets. Why not relax at home with a peony bouquet? Chinese peonies, or Paeonia lactiflora, are indigenous to central Asia, which stretches from northern China through Mongolia and eastern Siberia.
Which method of planting peony is best?
- Keep plants neat by deadheading and prune as needed (herbaceous only).
- When peonies become congested and produce fewer blooms, divide the plants.
- When the blossoms feel like soft marshmallows, cut the stems for bouquets. Water should contain Miracle-Gro for Fresh Cut Flowers.
When the peonies blossom, you can finally start to feel the arrival of summer. Around Memorial Day, when spring bulb flowers are starting to fade and summer blooms are beginning to emerge, these stunning perennials bloom profusely. Peonies are resistant to deer and rabbits, which is useful for gardeners who frequently experience issues with animals eating their plants. Peonies are frequently seen blooming despite years of neglect if you drive through old cemeteries or abandoned farmsteads. That is because to how simple peony are to grow!
How to Choose Peonies
Peonies come in four different varieties. They are forest peonies, tree peonies, herbaceous peonies, and intersectional peonies, in the order of blooming time. Herbaceous peonies, which thrive in zones 3–7, and tree peonies, which flourish in zones 3–9, are the two most popular varieties. Herbaceous plants often reach heights of two to three feet and spreads of two to four feet. With some types reaching heights of 7 feet, tree peony are more closely related to tiny shrubs. The type of peony you plant will depend on where you live and the style you’re going for because all peonies require similar maintenance. The focus of this paper will be on tree and herbaceous peony.
When to Plant Peonies
Fall is the ideal season to plant peonies. This is often when peonies purchased from a catalog will be delivered. It’s okay to plant peonies when you see them flowering and for sale in containers in the spring.
Where to Plant Peonies
Peonies require at least 6 to 8 hours of sunlight every day, though in zones 8 and 9, some shade from the sweltering afternoon sun is beneficial. Additionally, picking a location with sufficient air circulation is crucial to avoiding fungal illnesses.
How to Plant Peonies
In somewhat damp, well-drained soil, peonies thrive. Dig a hole, take the plant from the pot, and plant container-grown herbaceous peonies (the kind you buy in pots) so that the top of the root ball is level with the earth (any deeper and the peonies will not bloom). Fill up the area surrounding the plant by combining the discarded soil with an equal amount of Miracle-Gro Garden Soil for Flowers.
Before planting bare root herbaceous peonies, give them a brief dip in a basin of water to rehydrate them. Create a planting hole that is big enough to fit the roots, mix the soil as previously mentioned, and place a mound of the blended soil in the middle of the planting hole. Place the roots atop the mound and let them fan out and descend. Using the remaining blended soil, fill in the remaining portion of the hole, making sure that the “No more than 1 to 2 inches of soil should be present around the plant’s eyes (or growth buds) in order for it to bloom.
Deeper planting is required for tree peony. Unless they are grafted, peonies should be planted in the same soil combination as above, 2 to 4 inches deep at the crown (where the roots meet the stem). Check the label to see if the plant has been grafted, and then plant it such that the “The plant’s graft union, where the grafted top and rootstock are united, is located 4 to 6 inches below the soil line.
How to Stake Peonies
Peony stems are prone to toppling over after it rains, and the blossoms can become big and heavy. For herbaceous peonies, the best approach is to cover each plant in a peony cage in the spring, before the leaves begin to sprout (picture metal supports with rings for the flowers to grow up through). This is far more effective than attempting to hold each flower stalk separately, and it also looks nicer than wrapping the entire plant in string and cinching it in like a belt.
One stake can be used to stake tree peonies. Place the stake next to the stem in the ground, and then use a piece of twine to loosely secure the plant to the stake.
How to Water Peonies
When planting, give everything plenty of water. When the spring foliage begins to emerge and the flower buds start to show, give the plants another drink. Although peonies do not have a thirst, they will benefit from watering during dry spells for a year following the first planting.
How to Feed Peonies
Your peony will benefit from a powerful combination of care that includes excellent soil and the ideal plant food. Give peonies the nutrition they require by feeding them Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food in addition to the soil improvements indicated above for stunning color and more flowers than unfed plants. Peonies should be fed twice a year: the first time, right after they emerge in the spring (when the new shoots are 2 to 3 inches tall but before the flower buds are pea-sized), and the second time, in the middle of the growing season (about three months after the first feeding), to help them develop sturdy roots before the arrival of winter. Make sure you adhere to label instructions.
How to Help Prevent Problems with Peonies
Although mostly fuss-free, peonies occasionally experience fungal issues. Browning and failure to open flower buds are symptoms of botrytis. Brown patches on leaves are a symptom of some fungus illnesses. Infected blooms and leaves should be simply pruned off and disposed of (do not compost) in order to control these problems. Additionally, keep the plants neat, remove old foliage at the end of the season, and deadhead spent blooms. Peony blooms occasionally draw ants, but they won’t hurt the plants, so you can ignore them. (Contrary to popular belief, peonies do not require ants to blossom.)
How to Prune Peonies
Cut back each flower stalk on herbaceous peonies once all of the blooms have faded to just above a leaf, low enough so that the stem doesn’t protrude above the rest of the leaves. Unruly tree peony can be trimmed either in the spring or the fall (right before plants go dormant). However, any stems you trim back in the fall will not blossom the following spring (as you will be cutting off the flower buds). After blooming in the spring, you can prune. Anytime you choose to prune, be careful not to take more than one-third of the plant with you.
How to Divide Peonies
It is ideal to leave tree peony alone (undivided) so they can flourish for many generations in the garden. If the clumps have become too large or the flowering has slowed, herbaceous peonies can be divided. Herbaceous peonies can be divided by digging up the entire clump and rinsing it off to reveal the plant’s numerous roots and eyes (or buds). Leave as least one large root and three to four eyes per clump after cutting the plant apart with clean, sharp pruners. Replant, adhering to the bare root peony planting directions above. The plants might or might not flower the first year after dividing, so keep that in mind.
How to Cut Peonies for Bouquets
Timing is crucial. Buds should feel roughly as firm as a soft marshmallow when squeezed, which is known as the “soft marshmallow stage.” Examining the bud’s coloration is another method for determining when to cut. The majority of the bud’s exterior should remain green, but you should be able to make out approximately half an inch of the flower’s vibrant petals. Although cutting the flowers at this point lessens the possibility of bringing ants inside with them, it is still advisable to inspect the flowers before bringing them inside. Plants should open up when stems are placed in a vase of water. For longer-lasting blooms, change the water every few days and apply Miracle-Gro for Fresh Cut Flowers (vs. water only).

How big can a peony named Karl Rosenfield grow?
24-36″ broad by 24-36″ height. Karl Rosenfield is an antique hybrid with enduring appeal that each year offers a stunning display of brilliant blooms. When the double flowers open, their eye-catching contrast centers are bright yellow. Strong stems are great for cutting, and fragrant flowers keep well in vases. In mixed borders, the bouncy blooms perched on broad, deeply cut leaves create a lovely early-season accent. After flowering, the plant develops thick, dark green foliage, a rounded form, and a seasonal framework. In the autumn, foliage frequently develops a rich crimson color. Peonies are hardy, low-maintenance plants that can withstand freezing temperatures. For best flowering, plant them in a bright area, and cut off faded blossoms as soon as they appear. Plants should be pruned back once their fall foliage has fallen. Peonies have a lengthy lifespan and don’t need to be divided.
If you reside in an area where peonies are grown, late spring is the time to plant them. They grow in beds, borders, and along roadways in some homes, and wherever they do, they produce what is perhaps the season’s most gorgeous clump of blooming. Large, often fluffy flowers surrounded by shiny green foliage.
Expert gardeners refer to perennial peonies as investment plants. They represent some of the most durable landscaping materials available. Many plants actually continue to bloom magnificently for much over a century. Once they are established, they are just as resilient and dependable as oaks, giving your yard an amazing season of blossom year after year.
Peony planting It’s simple to add peonies to your landscape. All you need is decent soil and direct sunlight. Keep them outside in the sun because the bloom will be sparse or nonexistent if they are even partially shaded. The majority of gardeners are aware that the roots resemble a clump of carrots since they are thick, long, and tapering masses that grow every year. If you provide them food and water, the clumps will grow quickly and produce an increasing number of blooms.
Peony varieties: There are thousands of both new and old hybrids within the basic perennial peony species, Paeonia lactiflora. There are several kinds of flowers as well: The peonies with just one row of overlapping petals are the large, wide-open “single” varieties. They provide dinnerplate-sized beauty that is truly unsurpassed in the garden, much like enormous poppies. Since of our obsession with petals in America, single flowers are less common in gardens because people prefer the double flowers. The magnificent Krinkled White, an enduring classic, is one of the most well-known hits. The bloom form of Japanese peonies, which should not be confused with Tree Peonies, which frequently originate from Japan, is similar to that of singles but has a more ornate center. The popular, gorgeous Bowl of Beauty is a superb example, with its gleaming cherry red petals and fluffy yellow center creating an amazing color contrast. Peonies that are semi-double are simply that. They have the same basic bottom row of huge petals (often referred to as the guard petals) as single flowers, but on top, more shorter petals are emerging from the center. The gorgeous crimson Edulis Superba is a perfect illustration. Bomb peonies have huge, flat guard petals with a cluster of petals resting on top of them, resembling a fluffy snowball on a dish. The exquisite Laura Dessert and the dramatic Raspberry Sundae, two of the most popular and spectacular peonies, are dynamite. There are many different types of bombs, as these two examples show. With Raspberry Sundae, the huge bomb not only increases the flower’s size and height, but it also adds a magnificent palette of three hues to the overall bloom: white guard petals, a yellow collar, and a pastel pink core. All of the colors in Laura Dessert is white, with a tinge of lemon yellow in the bomb. The most widespread and most extensively planted peonies are undoubtedly double varieties. Excellent examples include Sarah Bernhardt, the perennial favorite double pink with enormous flowers and wonderful scent, and Festiva Maxima, the well-known Victorian introduction with its dazzling white blossoms with scarlet flecks. The red Karl Rosenfield and white Shirley Temple are two additional common duplicates.
With peonies, a gardener’s joy truly knows no bounds. All of them work well for cutting. All summer long, the foliage remains glossy and green, and they seldom ever attract pests. (The Tree Peony is a different species from the common perennial peony. Tree peonies are more like shrubs and do not entirely wither away each winter.)
Fragrant flower and foliage, good for cut flowers, deer and rabbit resistant, great for mass plantings
