Peony Paeonia lactiflora 'Karl Rosenfield'
ABOUT
The Karl Rosenfield peony is a perennial plant renowned for its stunning and opulent blooms. These flowers are particularly eye-catching, characterized by a deep cranberry red or magenta hue, and they display an enticing double form, meaning the flowers are full of layered petals. These petals possess a soft, silky texture and often glisten in the sunlight as if sprinkled with dew, adding to the visual complexity of the blooms. In the center of the flower, a cluster of smaller, golden-yellow stamens can usually be found, creating an appealing contrast to the red petals and adding an extra layer of color depth to the overall appearance. The plant itself is comprised of a robust, lush green foliage that serves as a rich backdrop to the dramatic flowers. The leaves are large, smooth, and have a somewhat shiny surface that reflects light, enhancing the plant’s vigorous appearance. The dark green color of the leaves contrasts beautifully with the striking red of the blooms, making the flowers stand out even more. While blooming, the Karl Rosenfield peony can become the centerpiece of any garden, providing a burst of vibrant color. Its flowers are not only a feast for the eyes but also emit a delightful fragrance – sweet and subtly perfumed – which can attract both admirers and pollinators alike. The scent is most pronounced on warm, sunny days and can fill the surrounding air, making the area near the blooms quite aromatic. Overall, the Karl Rosenfield peony is a classic garden choice, admired for its luscious, full blooms that evoke a sense of traditional elegance and beauty. Its striking presence is a highlight in spring to early summer gardens, and the plant is often used in floral arrangements and bouquets, especially favored for special occasions due to its lush appearance and enchanting fragrance.

WaterPeonies, including the 'Karl Rosenfield', require consistent watering, especially during the dry spells of summer. Water deeply once a week, providing about an inch of water through rainfall or supplemental watering. In general, this equates to roughly 0.6 gallons for each square foot of soil. It's important to avoid overhead watering to prevent fungal diseases—water at the base of the plant instead. During the fall, reduce watering as the plant prepares for dormancy.
LightThe 'Karl Rosenfield' Peony thrives in full sun to partial shade. It needs at least six hours of sunlight each day to bloom properly. The best spot for planting is in an area that receives morning sunlight and afternoon shade, especially in regions with hot summers, to protect the flowers from wilting.
TemperaturePeonies like 'Karl Rosenfield' prefer temperate climates and are hardy in USDA zones 3 to 8. They can survive winter lows down to -30°F and are quite cold-hardy. The ideal temperature for peonies is between 65°F and 75°F during their growing season. Peonies require a period of winter chilling (below 40°F) to set buds for the following spring.
PruningPrune 'Karl Rosenfield' Peonies in the fall after the foliage has died back to remove spent leaves and stems, which helps prevent disease. Cut the stems to just above ground level. Doing this once a year is typically sufficient maintenance for peonies. The best time to do this is after the first frost when the plant enters dormancy.
CleaningAs needed
SoilThe Peony 'Karl Rosenfield' thrives in well-draining, fertile, loamy soil with a pH ranging from 6.5 to 7.5. To create the best soil mix, combine equal parts garden soil, compost, and perlite or sand to ensure good drainage. Amend the soil with organic matter annually to maintain fertility.
RepottingPeonies like 'Karl Rosenfield' rarely need repotting as they are perennial plants that prefer to be undisturbed. They can remain in the same location for up to 10 years or more. Only repot or divide when the plant is overcrowded, typically after many years.
Humidity & MistingPeonies, such as 'Karl Rosenfield', are adaptable to a wide range of humidity levels typical of outdoor garden environments. They do not have specific humidity requirements and can thrive in average ambient humidity.
Suitable locationsIndoor
Provide bright light, cool temperatures, and proper planting depth.

Life cycleThe life of a Peony 'Karl Rosenfield' begins with seed germination, which occurs in late winter to early spring, given stratification is completed to break seed dormancy. Following germination, root development and shoot emergence mark the establishment of seedlings, which may take several years to mature before flowering. Once mature, the perennial phase begins with vigorous growth in early spring as temperatures rise; foliage emerges followed by stems that develop into large, showy flowers typically by late spring to early summer. After the blooming period, the plant enters a phase of energy accumulation, storing resources in the root system throughout the summer. As autumn arrives, foliage begins to die back, signaling the plant's entrance into dormancy, which it maintains through the winter months. With the onset of the following spring, the cycle restarts with the peony exiting dormancy, resuming growth, and preparing for another season of blossoming.
PropogationPropogation time
Early spring
The most widely used method for propagating the peony, specifically the Paeonia lactiflora 'Karl Rosenfield', is through division. This method is typically done in the fall after the plant has gone dormant. Gardeners should carefully dig around the peony to lift the entire plant from the ground, gently shaking off any excess soil. The root ball should be divided into sections, ensuring that each division has at least three to five eyes, which are the small reddish buds found on the crown of the root. The divisions can then be planted in well-drained soil at a depth where the eyes are approximately 1 to 2 inches (2.54 to 5.08 centimeters) below the surface of the soil. It is crucial to provide ample water for the newly planted divisions to establish a strong root system before the onset of winter.
