Peonies start the summer off with a bang. Their showy, often fragrant, blooms are hard to resist. The plant is a familiar perennial; many people have childhood memories of the flowers growing in a grandparent's yard and they have a sense of old-fashioned, nostalgic charm about them. No matter what type of garden you have, peonies are a wonderful addition, either as a mass planting or in a mixed flower border.

Peonies characteristics

Growing Peony Flowers in Your Garden

Peony flowers bloom in late spring or early summer, and their deeply cut leaves remain attractive all summer long. Hundreds of cultivars are available in colors such as pure white, pale pink, pale yellow, crimson, and fuchsia. Flowers may be single, semi-double, double, or Japanese type. Japanese type flowers have a ring or two of petals around a cluster of fluffy, modified petal-like stamens.

Peony plants are easily grown in zones 3 through 8. They thrive in full sun. Peonies tolerate light shade but will flower less profusely. While plants are low-maintenance perennials once established, they do require good soil preparation. Peonies need well-drained, fertile soil. They don't like to sit in water. Use compost to amend your soil if necessary.

Peonies are long-lived; some have even been known to live for 50 to 70 years.

Planting Peonies

Peonies like rich, moist, well-drained topsoil and tolerate full sun or partial shade, though in hot southerly climates they are happiest with morning sun only. Fall is the best season for planting so the roots can get well established before top growth begins the following spring. However, spring is also an acceptable planting season.

They can be purchased as bare-root plants for planting in the fall. Container-grown plants may be planted in the spring.

Proper planting depth is important; if buried too deeply, they will not bloom.

  1. Plant peonies so their crown buds are no more than two inches below the soil surface.
  2. Choose your planting site carefully; plants don't like to be moved.
  3. Be sure to space at least three feet from other plants. They will fill in the space as they mature.
  4. After planting, place 2 to 3 inches or organic mulch around the base of each plant. Mulch helps retain moisture in the soil and keeps down weeds. Don't let mulch touch the stem though; wet mulch on the crown can cause it to rot.

Caring for Peonies

Plants don't require much maintenance. If your plant is thriving in well prepared, fertile soil, you don't need to fertilize it. Simply work organic material such as compost into the soil around the plant each spring.

  • Provide regular water for the first season or two while the plant develops its root system. Once established, they are very drought tolerant.
  • Staking is often necessary, especially for double-flowered or tall, weak-stemmed varieties. The easiest way to support is with a metal hoop, which can be purchased at garden stores. Place the hoop over the plant in early spring, and the stems will grow up inside the rings.
  • Remove all spent blossoms as they fade. This allows the plant to put all its energy into its root system for next year's growth.

Dividing and Transplanting Peonies

Peonies don't need frequent division. In fact, they prefer not to be disturbed. But you may divide as a means to increase your stock or to ease overcrowding in an older clump. Late summer or early fall is the best time to do this. Dig up the entire clump and cut it into sections with a sharp knife. Be sure to dig deeply, as they have extensive root systems.

Transplant the newly-divided peony sections into your garden and water well. Adding a two-inch layer of mulch will retain moisture and help them get off to a good start.

Peony Pests and Disease

Peonies are fairly robust plants that are rarely bothered by pests and disease if their preferred growing conditions are provided.

Botrytis, powdery mildew, and other fungal diseases occur easily if the peony's soil is not well-drained. Poor air circulation also exacerbates these conditions, so it's important to not plant peonies too densely and to thin them out as they grow. If powdery white splotches, yellow deformed leaves, or any other signs of disease appear, remove the infected parts of the plant immediately and dispose of them to prevent it from spreading.

Mites, scale, and aphids all show up from time to time on peonies, though these are easily treated with a blast of water from the hose or by applying insecticidal soap.

Peony Varieties

Some peony varieties available today are old favorites. There are many interesting new introductions as well. Early-, midseason- and late-blooming cultivars are available. Here are a few varieties to try.

  • Festiva Maxima produces huge, loose rose-like flowers of pure white flecked with crimson. Its vigorous habit, fabulous color, and fragrance have made it a popular cultivar for over 150 years. Blooms early.

Peony Garden Companions

Because peonies have short bloom periods, you will want to plant them with other flowering plants. Flowers combine well with a wide range of perennials and shrubs.

  • Plant in front of Phlox paniculata. Just as the blossoms are winding down, phlox is getting ready to put on its show.
  • Peonies mix well with flowering trees and shrubs such as late-blooming lilacs.
  • Interplant with spring bulbs such as tulips or daffodils to mask dying bulb leaves.
  • Other perennials to complement include columbine, coral bells (Heuchera), iris, and catmint (Nepeta).

The Pleasure of Peonies

Peonies are one of the most majestic species to include in a perennial border. Unlike many perennials that fade away after a few years, peonies bring their beauty to the garden each spring for a decade or more.
