Paeonia lactiflora ‘Mr. Ed’: The Charming Chameleon of the Peony Garden
Paeonia lactiflora ‘Mr. Ed’, also spelled ‘Mister Ed’, is a truly enchanting cultivar that brings both surprise and elegance to the garden. Belonging to the family Paeoniaceae, this midseason peony is celebrated for its unique, color-changing double blooms and soft fragrance. Known for its reliability and performance, ‘Mr. Ed’ has become a favorite among peony lovers, garden designers, and florists alike.
A Bloom Full of Surprises
The defining trait of Paeonia lactiflora ‘Mr. Ed’ is its fascinating ability to produce blossoms in various shades of pink and white. Some flowers open blush pink and fade to creamy white, while others may show a gradient of both tones within a single bloom. Occasionally, blooms on the same plant differ in coloration, creating a whimsical, painterly effect across the bush.
Each flower is a lush, bomb-type double, filled with layers of delicately ruffled petals that measure up to 6 inches (15 cm) in diameter. While not overpowering, the blooms offer a soft, sweet fragrance that adds sensory depth to the garden experience.
Growth Habit and Structure of Paeonia lactiflora ‘Mr. Ed’
‘ Mr. Ed’ grows into a rounded, bushy clump reaching about 36 inches (91 cm) tall and wide. It produces sturdy, upright stems that support its heavy blooms better than many other double-flowered peony cultivars. Still, a discreet peony ring or support may be helpful during wind or heavy rain.
Bloom Time and Seasonal Impact
This cultivar is classified as a midseason bloomer, typically flowering in late spring to early summer depending on the local climate. When it arrives, it makes an unforgettable impression—especially in gardens designed for staggered bloom sequences. ‘Mr. Ed’ fills the gap between early and late-season peonies, creating a seamless transition of color and fragrance.
How to Grow Paeonia lactiflora ‘Mr. Ed’
Light
For best performance, plant ‘Mr. Ed’ in full sun, where it will receive at least 6 hours of direct sunlight daily. While it can tolerate light shade, too much shade may reduce blooming.
Soil
Peonies prefer fertile, well-drained soil with a neutral to slightly alkaline pH (6.5–7.5). Improve heavy clay soils with compost or aged manure to enhance drainage. Avoid planting in waterlogged conditions.
Watering
Water regularly during the growing season, particularly in dry periods. Once established, ‘Mr. Ed’ is moderately drought tolerant but will perform best with consistent moisture. Avoid overhead watering to minimize the risk of fungal diseases.
Fertilizing
Apply a balanced fertilizer (10-10-10) in early spring as shoots emerge. A second application after blooming can support root development and next year’s buds. Avoid over-fertilizing, which can result in lush foliage at the expense of flowers.
Planting Depth
Plant bare-root divisions so that the eyes (buds) are no more than 1 to 2 inches (2.5–5 cm) below the soil surface. Planting too deep may inhibit blooming.
Maintenance and Support
‘ Mr. Ed’ is a relatively low-maintenance plant. Deadhead spent flowers promptly to tidy the plant and conserve energy for root and bud development. In fall, cut the stems back to just above ground level to prevent overwintering pests or diseases.
Although its stems are sturdy, large flowers can cause them to bow under pressure. Installing a support ring in early spring helps maintain upright structure and enhances the display.
Pests and Diseases
While ‘Mr. Ed’ is generally hardy and resilient, several pests and diseases can occasionally affect its health. Among the potential insect threats are aphids, spider mites, mealybugs, and red-headed flea beetles, all of which may feed on foliage or flower buds, reducing plant vigor. Japanese beetles and thrips can also target blooms and leaves. Leaf and bud eelworms or caterpillars like the swift moth larva can distort growth and damage stems.
On the disease front, gardeners should monitor for peony leaf blotch (also known as measles), peony wilt (Botrytis blight), root rot, and powdery mildew. Fungal threats such as honey fungus, Verticillium wilt, and Phytophthora blight can cause wilting, stem dieback, or root decay. Viral infections and damage from nematodes may result in stunted, yellowed plants with poor bloom performance.
Good cultural practices are key to prevention. Plant in well-drained soil, avoid overhead watering, ensure proper spacing for air circulation, and clean up plant debris in fall. Regular inspection and prompt response to symptoms will help keep ‘Mr. Ed’ healthy and blooming at its best.
Landscape and Design Value
The whimsical, color-shifting blooms of ‘Mr. Ed’ provide striking focal points in perennial borders, cottage gardens, and mixed beds. Its bold blossoms and rich foliage pair well with iris, catmint (Nepeta), alliums, and salvia. It also works beautifully as a specimen planting or in mass displays along paths and walkways.
Gardeners appreciate ‘Mr. Ed’ not only for its unique flowers but also for its deer resistance, long lifespan, and excellent performance as a cut flower. When harvested at the soft bud stage, the blooms open fully indoors and last for a week or more in arrangements.
Propagation and Longevity
Peonies are famously long-lived. Once established, ‘Mr. Ed’ can thrive in the same location for decades. Division is best done in fall, typically after the foliage has died back. Gently lift the clump and divide the crown, ensuring each section has at least 3–5 healthy buds and sufficient roots. Replant promptly at the proper depth.
Final Thoughts on Paeonia lactiflora ‘Mr. Ed’
Paeonia lactiflora ‘Mr. Ed’ is a stunning, garden-worthy peony that blends charm, strength, and surprise. Its dual-colored blooms, gentle fragrance, and sturdy habit make it a versatile addition to the landscape.
