PeoniesPaeonia (pay-oh-nee-ah), peony; Paeoniaceae Family. Popular, long-lived hardy perennial of both herbaceous and shrubby tree form. It is grown in the Northern Temperate region for its showy single or double blooms that appear in late May and early June. Foliage of the herbaceous types is decorative, with compound leaves that last well until the first frost and are erect on strong stems. In herbaceous varieties, the entire plant gives a bushy effect ranging from1 1/2 to 3 1/2 feet in height. Five wild species, all from China, account for most of the hybrids available today. Japanese and single-form peonies have large flat blossoms with a mass of stamens at the center. Double forms produce heavy ball-like heads.

For well over a century, peonies have proven themselves to be beautiful yet tough, low maintenance perennials. In the garden, peonies require little attention, making them a perfect choice for beginning gardeners and busy moms.
A sunny or partly shady site is ideal for garden peonies. Protection from afternoon sun and from harsh winds will help to prolong the lives of the exotic flowers. Peonies will perform best in well-drained, evenly moist, rich soil with a pH near neutral. Though peonies may be slow to develop their deep, substantial root system, peonies can live 50 years or more.

Use peonies as border plants or mass planting; plant in rows to create a hedge. Peonies exhibit a high degree of drought tolerance (once established), and are pest, disease and deer resistance; plus their fragrant flowers are great for cut and dried flowers. 

Peonies flower type

PLANTING: Space plants 3 ft apart in full sun or light shade, the latter being preferable in southern zones. The ideal soil is rich and moisture retentive, but well drained. Dig a hole 2 feet square and deep, mixing the soil with liberal amounts of humus or well-decomposed compost, along with some bonemeal. Set the root clumps in the hole so that the 'eyes' or growing points are covered with no more than 1-2 inches of soil. Do not plant too deeply or your peony will not prosper. Firm the soil around the plant after planting and water well. For more information, click on Growing Peonies.

MAINTENANCE: It is vital that these plants be kept well watered during their growing season. As peonies are heavy feeders, fertilize each spring with a high phosphorous fertilizer after growth has started. When cutting, remove as little foliage as possible, since the leaves are necessary for plant growth and vigor. Remove spent flowers and, in the fall, cut back dead foliage. Established plants prefer not to be moved. In situations exposed to heavy winds, staking or a plant support hoop may be necessary.

Types of Peonies:

There are three main types of peonies:

  • Herbaceous peonies: These are the most common type, dying back to the ground each winter and re-emerging in spring. They are known for their large, showy flowers and sturdy stems.

Planting peonies requires some specific steps to ensure they thrive and reward you with their beautiful blooms. Here is a guide to get you started:

When to plant:

  • Bare-root peonies: The ideal time to plant bare-root peonies is in fall, between October and March, before the ground freezes. This allows them to develop a good root system before the spring growth spurt.
  • Potted peonies: Potted peonies can be planted in early spring when the danger of frost has passed.

Choosing a location:

  • Sunlight: Peonies need full sun, at least 6-8 hours daily. Partial shade might be tolerated in hot climates.
  • Drainage: The soil must be well-draining to prevent root rot. If your soil is heavy clay, amend it with compost or sand to improve drainage.
  • Space: Depending on the variety, space your peonies 3-4 feet apart to allow for good air circulation and future growth.

Planting steps:

  • Dig a hole: Dig a hole 1.5-2 times wider and deeper than the root system of your peony. Aim for a depth where the "eyes" (buds) on the crown are 2-3 inches below the soil surface.
  • Amend the soil: Mix compost, aged manure, or other organic matter into the bottom of the hole to enrich the soil and improve drainage.
  • Prepare the root: For bare-root peonies, carefully tease out any tangled roots. Cut any damaged or diseased roots with sharp pruners.
  • Position the peony: Place the peony in the hole with the "eyes" facing upwards. Ensure the crown is no more than one inch below the soil surface.
  • Backfill and water: Fill the hole with soil, gently firming it around the plant. Water thoroughly to settle the soil.
  • Mulch: Apply a 2–3-inch layer of mulch around the base of the plant to retain moisture and suppress weeds.

Additional tips:

  • Do not fertilize newly planted peonies in the first year.
  • Water regularly, especially during the first growing season. However, avoid overwatering.
  • Do not cut back the foliage in the fall until it turns brown and dies naturally. This allows the plant to store energy for the next season.
  • You can expect your peonies to bloom 3-5 years after planting.

Remember: Patience is key with peonies. Once established, they require minimal care and will reward you with years of stunning blooms!

Caring for peonies is easy once they are established, but it is important to provide them with the right conditions to thrive and reward you with their stunning blooms. Here is a guide to keep your peonies happy and healthy:

Watering:

  • Newly planted peonies: Water deeply and regularly, especially during the first growing season, but avoid overwatering. Aim for consistent moisture without soggy soil.
  • Established peonies: During their growing season, water deeply when the top inch of soil feels dry. Reduce watering frequency as they go dormant in fall.

Feeding:

  • Newly planted peonies: Do not fertilize in the first year. They should have enough nutrients from the planting mix.
  • Established peonies: In early spring, apply a light topdressing of compost or aged manure around the base of the plant, avoiding direct contact with the stems. Alternatively, you can use a balanced fertilizer according to package instructions. Avoid overfertilizing.

Sunlight:

  • Peonies need full sun, at least 6-8 hours daily, for optimal blooming. Partial shade might be tolerated in hot climates but expect fewer blooms.

Support:

  • The large blooms of some peonies can become heavy and flop over. Stake your peonies as needed, using discreet supports like wire mesh cages or plant rings.

Deadheading:

  • Once the blooms fade, remove the spent flower heads to prevent the plant from setting seed, which can weaken it. Cut the stems back to healthy foliage but leave most of the leaves intact as they are important for photosynthesis.

Fall Cleanup:

  • After the foliage turns brown and dies naturally in fall, cut back the stems to ground level and remove any diseased or fallen leaves. This helps prevent the spread of fungal diseases.

Winter Protection:

  • In colder climates, apply a light layer of mulch (2-3 inches) around the base of the plant after the ground freezes. This helps protect the roots from harsh winter conditions.

Dividing:

  • Established peonies (usually after 7-10 years) can be divided in early fall or early spring. This process rejuvenates the plant and increases bloom production. However, dividing is best left to experienced gardeners as it can be tricky.

General Tips:

  • Do not disturb the root system of established peonies, as they resent transplanting.
  • Avoid planting peonies too deeply, as this can prevent them from blooming.
  • Be patient – it may take 3-5 years for newly planted peonies to bloom abundantly.

By following these simple care tips, you can enjoy your peonies for years to come!

By being informed about specific varieties and following responsible gardening practices, you can enjoy the beauty of peonies in your garden while minimizing any potential ecological risks.

The best time to propagate Paeonia (peonies) depends on the method you choose:

Division:

  • Fall: This is the preferred and most successful time for dividing peonies. The ideal window typically falls between late summer (August) and early fall (October) before the ground freezes. During this period, the plants have finished their growing season and stored energy in their roots, making them well-equipped to handle the stress of division and establish themselves before winter.
  • Early spring: While less ideal than fall, dividing peonies in early spring (March-April) before new growth emerges is also possible. However, the success rate might be slightly lower than in fall, and the plants might have less time to establish before the summer heat.

Seeds:

  • Fall: Seeding peonies in the fall allows for natural stratification (exposure to cold temperatures) which aids germination. Sow seeds outdoors in a prepared seedbed before the ground freezes and mulch lightly for winter protection. They will germinate the following spring.

Important points to remember:

  • Age of the plant: Peonies are best divided when they are mature and well-established, typically after 3-5 years of growth. Avoid dividing young plants.
  • Weather conditions: Ensure the weather is cool and moist, not hot, and dry, when dividing or sowing seeds.
  • Preparation: Properly prepare the planting area and follow good hygiene practices during propagation.

By choosing the appropriate time and following best practices, you can increase your chances of successfully propagating your peonies and enjoying their beauty for years to come!
