Peonies are among the most beloved flowering plants in landscaping, admired for their large, lush blooms and delightful fragrance. These perennials are known for their longevity, often thriving for decades with minimal care, making them an excellent investment for any garden.
How To Use Peonies For Landscaping
Whether you want to create a formal landscape or a natural cottage garden, peonies can add elegance, structure, and seasonal charm to your yard.
In this post, we’ll explore how to choose the right peonies, design your landscape with them, and maintain their health throughout the seasons.
Choosing the Right Peony Varieties
Types of Peonies
There are three main types of peonies, each with unique characteristics that influence their suitability for landscaping:
Herbaceous Peonies: These are the most common and die back to the ground each winter. They produce large, showy blooms in late spring to early summer and are ideal for garden beds and borders.
Tree Peonies: These woody shrubs retain their structure year-round and produce large, exotic-looking flowers that bloom earlier than herbaceous peonies. They work well as focal points in landscapes.
Intersectional Peonies: A hybrid between herbaceous and tree peonies, these plants have the strong stems of tree peonies but die back like herbaceous peonies in winter. They bloom for an extended period and offer a diverse range of colors.
Best Varieties for Different Climates
Peonies thrive in USDA hardiness zones 3-8, but some varieties are better suited for specific climates:
Colder Climates: ‘Sarah Bernhardt’, ‘Karl Rosenfield, and ‘Festiva Maxima’ are reliable options for colder regions.
Warmer Climates: Tree peonies and heat-tolerant varieties like ‘Coral Charm’ and ‘Bartzella’ (Itoh) perform better in warm climates where winters are milder.
Fragrance Preference: If fragrance is a priority, choose varieties like ‘Duchesse de Nemours’ or ‘Dr. Alexander Fleming’.
Planning Your Peony Landscape Design
Selecting the Right Location
Peonies thrive in full sun (at least 6 hours per day) and well-drained soil. Avoid planting them in overly shaded areas, as this can lead to poor blooming and weaker stems.
Choose locations with good air circulation to prevent fungal diseases like botrytis.
Designing with Color and Bloom Timing
Peonies come in various shades, including white, pink, red, coral, yellow, and even lavender tones. When designing a landscape, consider layering different varieties to extend the bloom season:
Early Bloomers: ‘Coral Charm,’ ‘Paula Fay’
Mid-Season Bloomers: ‘Sarah Bernhardt,’ ‘Karl Rosenfield’
Late Bloomers: ‘Duchesse de Nemours,’ ‘Felix Crousse’
Companion Planting with Peonies
To create a balanced garden, pair peonies with complementary plants:
Tall Companions: Delphiniums, foxgloves, and alliums add height.
Low-Growing Plants: Nepeta (catmint), lavender, and hostas help cover peony foliage as it fades in late summer.
Shrubs & Evergreens: Boxwood hedges or small conifers provide a structured backdrop.
Planting and Caring for Peonies
Best Time and Method for Planting
Peonies are best planted in the fall, allowing their roots to establish before winter. When planting:
- Dig a hole at least 2 feet wide and 18 inches deep to ensure proper root development.
- Amend the soil with compost or well-rotted manure to enhance fertility and drainage.
- For herbaceous peonies, place the roots so the eyes (buds) are no more than 1-2 inches below the soil surface; planting too deeply can result in poor flowering.
- Tree peonies should be planted deeper, with the graft union buried 4-6 inches below the soil surface to encourage strong growth.
- Water thoroughly after planting and apply mulch for winter protection, being careful to keep the mulch away from the base of the plant to prevent rot.
Watering, Fertilizing, and Mulching
Watering: Peonies require deep watering about once a week, especially in dry periods. Avoid overwatering, as they dislike soggy soil, which can cause root rot.
Fertilizing: Apply a low-nitrogen fertilizer (such as 10-10-10) in early spring when new growth emerges. A second application can be made after flowering to support root development for the next season.
Mulching: A light layer of mulch (such as shredded bark or straw) can help retain moisture and suppress weeds. However, avoid piling mulch against the crown of the plant to prevent rot.
Common Pests and Diseases
Botrytis Blight: A fungal disease that causes blackened stems and buds. Prevent it by providing adequate air circulation and avoiding overhead watering.
Ants on Peony Buds: While commonly seen on peony buds, ants do not harm the flowers; they feed on nectar and may even help protect the plant from other pests.
Powdery Mildew: A white, powdery fungus that appears in humid conditions. Improve airflow by spacing plants properly and pruning back affected foliage.
Root Rot: Caused by overly wet soil. Ensure well-draining soil and avoid excessive watering.
Seasonal Maintenance and Pruning
Spring Care
- Support taller peony varieties with stakes or rings to prevent drooping.
- Apply a balanced fertilizer to encourage strong growth.
- Remove any dead stems or leaves from the previous season to prevent disease.
Summer Care
- Deadhead spent flowers by cutting just above the nearest leaf node to maintain a tidy appearance and encourage further growth.
- Continue deep watering during dry periods to keep plants hydrated.
- Monitor for pests and diseases, addressing any issues promptly.
Fall Care
- Cut back herbaceous peonies to 1-2 inches above the soil to prevent disease.
- Tree peonies should only have dead or weak branches removed, as they do not die back completely.
- Apply compost or organic matter around the base of the plant to enrich the soil for the following season.
Winter Protection
- In colder regions, apply a light mulch (such as pine needles or straw) to protect the roots from extreme frost. Remove mulch in early spring to allow for new growth.
- Avoid heavy pruning of tree peonies, as their woody stems help them withstand winter temperatures.
Showcasing Peonies in the Front Yard
Using Peonies as Elegant Borders
Peonies make excellent border plants along walkways, driveways, or fences. Their lush foliage provides greenery even after blooms fade, and their vibrant flowers create an inviting atmosphere.
Creating a Welcoming Entryway
Placing peonies near the entrance of your home can add a luxurious touch. Pair them with evergreens for year-round structure, or mix them with low-growing flowers like petunias and alyssum for a layered effect.
Designing Formal or Cottage-Style Gardens
For formal gardens, plant peonies in symmetrical rows or structured clusters. In cottage-style landscapes, allow peonies to blend naturally with other perennials like roses, lavender, and daisies for a romantic, overflowing aesthetic.
Showcasing Peonies in the Backyard
Creating a Lush Peony Garden
A dedicated peony garden serves as a breathtaking focal point. Space peonies at least 3 feet apart to allow for proper airflow and avoid overcrowding. Mix early, mid, and late bloomers to extend the flowering season.
Incorporating Peonies in Mixed Flower Beds
Peonies blend beautifully with other perennials like lilies, salvia, and phlox. Arrange plants in layers, with taller perennials in the back and shorter ones in front, to create depth and visual interest.
Using Peonies in Raised Beds or Containers
Itoh peonies thrive in raised beds and large containers, making them ideal for patios and small gardens.
Choose deep, well-draining containers with nutrient-rich soil to support strong root growth. Water regularly but ensure proper drainage to prevent root rot.
Pairing Peonies with Shrubs and Grasses
Peonies pair well with ornamental grasses, which provide movement and contrast to their bold, structured blooms.
Low-maintenance shrubs like hydrangeas and spirea add additional seasonal interest and balance to the design.
