Paeonia lactiflora (also known as the Chinese Peony or the Common Garden Peony) are some of the most spectacular peony flowers you can grow. These herbaceous perennials not only add bursts of color to your garden, but their longevity makes them a worthwhile investment for any gardener. In this article, we’ll dive into the history, different types, and care tips for these beautiful blooms, along with practical advice on how to get the most out of your peonies from late spring to early summer.

A Rich History: The Origins of the Chinese Peony

The history of Chinese peonies goes back more than a thousand years. Native to northern China, Eastern Siberia, and Central Asia, these plants have long been admired for their beauty and medicinal properties. In ancient China, they were symbols of prosperity, romance, and honor. During the Tang Dynasty (618–907 AD), Chinese peonies were frequently depicted in poetry and art. They were also prized in traditional medicine for their roots and flowers, believed to treat ailments like inflammation.

By the 18th century, Paeonia lactiflora had made its way to Europe; the rest is history. The plant soon gained favor with European and North American breeders, many of whom—under the guidance of organizations like the American Peony Society—developed new cultivars that we still enjoy today. These breeders focused on enhancing the plant’s beauty and durability, creating some of our most beloved garden peonies.

Types of Chinese Peonies

When discussing peonies, it’s important to differentiate between tree peonies and herbaceous peonies. Paeonia lactiflora, the herbaceous peony, dies back to the ground each winter and then reemerges with fresh growth in the spring. These peonies, with their dark green leaves, offer a diverse range of colors, flower forms, and fragrances that can light up your garden in late spring and early summer.

Here are a few popular named cultivars:

• ‘Bowl of Beauty’: With large, cup-shaped flowers, the pale yellow stamens contrast beautifully against the striking pink petals. This peony variety thrives in full sun and is a great choice for adding drama to any perennial border or for creating stunning cut arrangements.
• ‘Festiva Maxima’: Known for its sweet fragrance and rose pink double flowers with occasional crimson streaks, this peony is both elegant and resilient. It’s also great as a cut flower, holding up well indoors.
• ‘Sarah Bernhardt’: This well-loved Chinese peony produces large, fragrant blooms that are a soft pink. Its cut flowers are frequently used in wedding bouquets and make a gorgeous addition to any vase.
• ‘Karl Rosenfield’: A bold variety, featuring deep crimson blooms. This cultivar’s robust growth makes it a striking presence in any garden bed, and it holds up well against hard rain.
• ‘Shirley Temple’: A charming semi-double variety that starts with blush pink blooms and fades to pure white as it matures. Its delicate peony flowers are perfect for both gardens and arrangements.
• ‘Duchesse de Nemours’: This refined herbaceous perennial has a creamy white color and a fragrance reminiscent of gardenias. It’s another great option for cut flowers.
• ‘Coral Charm’: With award-winning, semi-double coral blooms that fade to soft peach, this variety creates a dynamic display throughout its blooming period. Perfect for adding a touch of unique color to your garden.
• ‘Monsieur Jules Elie’: A classic choice with rose pink double flowers and a light silvery sheen. Its fragrant blooms make it a favorite for garden use and as cut flowers.

These many cultivars offer a wide variety of colors, shapes, and noteworthy characteristics, making them perfect for a range of garden designs, from formal to casual.

How to Care for Chinese Peonies

Caring for Chinese peonies is easier than many think. They are hardy, long-lived plants that can thrive for decades in the same spot if they’re happy. Here’s what you need to know to ensure success:

• Soil: Peonies thrive in well-drained, fertile soil with a slightly alkaline pH. If your soil is heavy or clay-like, consider adding organic matter, such as compost, for improved drainage. This will help avoid problems like botrytis blight, which can occur if the roots stay too wet.
• Sunlight and Spacing: Paeonia lactiflora needs full sun—at least six hours a day. In hotter climates, a bit of shade during the hottest time of the day can be beneficial. Ensure your peonies are planted with enough space (about 3-4 feet apart) to allow for proper air circulation, which helps prevent disease.
• Watering: Although peonies are somewhat drought-tolerant once established, they prefer regular, deep watering during the growing season, especially in dry spells. Be sure to water at the base of the plant to avoid wetting the foliage, which can promote fungal diseases.
• Fertilization and Mulching: Peonies benefit from a low-nitrogen fertilizer applied in early spring. This will support strong growth without promoting too much foliage at the expense of blooms. Mulch around the base of the plant helps retain moisture. But be careful not to cover the crown, as this can cause rot.
• Pruning and Deadheading: After flowering, remove spent flowers to keep the plant looking neat and to encourage more blooms. In early fall, cut the plant back to ground level to prevent disease. Discard the cut foliage, as it may harbor fungal spores that can overwinter and cause problems like botrytis blight.

Growing Chinese Peonies from Seed

If you’re feeling adventurous, you can try growing your Chinese peony from seed, though this method requires patience. Peonies grown from seed can take three to five years to bloom.

• Seed Collection and Preparation: After flowering, allow the seed pods to mature and split open naturally on the plant. Harvest the seeds and store them in a cool, dry place until ready for stratification. To break dormancy, peony seeds require a cold treatment, so place them in the refrigerator for 10-12 weeks.
• Planting: After stratification, plant the seeds in well-draining soil, about one inch deep. It’s best to plant them in early fall so they can experience natural winter conditions. Keep in mind that it may take a full year before you see any signs of growth, but the reward is well worth it.

Common Problems and Solutions

Even though peonies are robust, they can encounter a few common issues:

• Bulb mites: These pests can cause root damage and affect the overall health of the plant. Maintaining clean, well-drained soil helps prevent infestations.
• Botrytis blight: A fungal disease that thrives in wet, overcrowded conditions. Prevent this by ensuring good air circulation around your plants and avoiding overhead watering. If you spot it, remove and discard affected plant parts immediately.
• Lack of Blooms: If your peony isn’t blooming, it might be due to poor sunlight, over-fertilization, or planting the roots too deeply. Make sure your plant gets plenty of full sun and that the crown is no more than two inches below the soil surface.

Garden Ideas for Chinese Peonies

Chinese peonies are incredibly versatile, making them ideal for various garden styles.

• Perennial Borders: Plant peonies in the middle or back of your perennial borders where their tall stems and large blooms will stand out. They pair well with other perennials like lavender, delphiniums, or alliums to create a longer-lasting floral display.
• Cut Flowers: With their sweet fragrance and long stems, Chinese peonies make excellent cut flowers for bouquets or arrangements. Consider planting a few varieties that bloom at slightly different times to extend your harvest of cut flowers.
• Formal Gardens: If you have a formal garden, peonies work beautifully as focal points in symmetrical beds or alongside pathways. Their upright growth habit and stunning flowers fit perfectly into structured garden designs.

The Bottom Line

Chinese peonies are truly a gardener’s dream, offering years of vibrant blooms with minimal care. Their combination of beauty, fragrance, and resilience makes them a timeless addition to any garden. Whether you’re cultivating them for cut flowers, a perennial border, or simply to enjoy their stunning flower buds each season, these long-lived perennials are sure to reward you with decades of delight.
