Growing Peonies and Hydrangeas Together: A Perfect Pairing

Can You Plant Peonies and Hydrangeas Together?

When planning your garden, combining plants that complement each other both aesthetically and in terms of growing requirements can create a truly spectacular display. Two of the most beloved flowering plants among gardeners are peonies and hydrangeas. Both are known for their gorgeous blooms and classic garden appeal, but you might wonder if these two showstoppers can coexist harmoniously in the same garden space.

The good news is that yes, peonies and hydrangeas make excellent garden companions! These two flowering favorites not only look stunning together but also share similar care requirements once established. Their complementary blooming periods can provide your garden with extended visual interest throughout the growing season. In this comprehensive guide, we’ll explore everything you need to know about successfully growing these beautiful plants together.

Understanding Peonies and Hydrangeas

Before diving into their compatibility, let’s take a moment to understand each plant individually. This foundation will help you better appreciate why they work so well together and how to maximize their partnership in your garden.

All About Peonies

Peonies are herbaceous perennials known for their lush, fragrant blooms that appear in late spring to early summer. These long-lived plants can thrive in the same spot for decades, sometimes even outliving the gardeners who plant them! Peonies come in various forms including herbaceous varieties that die back to the ground each winter and tree peonies that maintain a woody structure year-round.

Some key characteristics of peonies include:

• Spectacular, often fragrant blooms in shades of white, pink, red, and yellow
• Early to mid-season flowering (typically May-June)
• Preference for full sun to light shade
• Require well-draining soil
• Relatively drought-tolerant once established
• Low maintenance after initial establishment

All About Hydrangeas

Hydrangeas are flowering shrubs beloved for their large, showy blooms that typically appear from mid-summer into fall. There are several species of hydrangeas, each with distinctive characteristics, but all share the trait of producing clusters of small flowers that form impressive flower heads.

Key characteristics of hydrangeas include:

• Large, showy blooms in various shapes (mophead, lacecap, panicle)
• Colors ranging from white, pink, blue, purple, and green (some varieties change color based on soil pH)
• Mid-summer to fall blooming period
• Preference for morning sun and afternoon shade in most regions
• Need for consistent moisture
• Variety of sizes from compact to quite large depending on cultivar

Why Peonies and Hydrangeas Work Well Together

Now that we understand each plant individually, let’s explore why peonies and hydrangeas make such excellent garden companions.

Complementary Blooming Periods

One of the greatest advantages of planting peonies and hydrangeas together is their sequential blooming periods. Peonies typically bloom in late spring to early summer, while most hydrangeas begin flowering in mid-summer and continue into fall. This creates a relay of blooms in your garden, with peonies passing the baton to hydrangeas as the season progresses. As your peonies finish their spectacular display, your hydrangeas are just getting started, ensuring continuous color and interest in your garden.

Similar Growing Conditions

Both plants thrive in similar garden conditions, making them compatible neighbors:

Aesthetic Harmony

Visually, peonies and hydrangeas create a beautiful cottage garden aesthetic when planted together. The lush, rounded forms of both plants’ blooms create a cohesive look, while their different growing habits (herbaceous perennials versus woody shrubs) add structural diversity to the garden. The peony’s fern-like foliage provides an attractive ground cover beneath the more substantial hydrangea shrubs, creating layers of interest in the garden.

Design Tips for Planting Peonies and Hydrangeas Together

Creating an effective garden design with peonies and hydrangeas requires some planning. Here are some design strategies to consider:

Plant Placement

When placing these plants in your garden, consider their mature sizes and growing habits:

• Position taller hydrangeas behind shorter peonies to create depth and ensure both plants receive adequate sunlight
• Plant peonies at least 3-4 feet away from hydrangeas to prevent competition for resources
• Consider planting peonies in front of deciduous hydrangeas where they can receive full spring sun before the hydrangea leafs out fully
• Use hydrangeas as a backdrop to showcase the peony blooms in late spring

Color Coordination

Consider color harmony when selecting varieties:

• Pair white peonies with blue or purple hydrangeas for a cool, elegant combination
• Combine pink peonies with pink or white hydrangeas for a romantic, cottage garden feel
• Create drama by contrasting deep red peonies with bright white hydrangeas
• Consider the seasonal color progression in your garden design

Seasonal Interest

Select varieties that provide interest throughout the growing season:

• Choose early, mid, and late-blooming peony varieties to extend their flowering period
• Select hydrangea varieties known for interesting fall foliage color
• Consider incorporating reblooming hydrangea varieties for extended flowering
• Include tree peonies or intersectional peonies alongside herbaceous varieties for structural winter interest

Care and Maintenance for Peonies and Hydrangeas

While both plants are relatively low-maintenance once established, there are some care considerations to keep in mind when growing them together:

Watering

The biggest difference in care requirements between these two plants is their watering needs. Hydrangeas generally prefer more consistent moisture than peonies, which are more drought-tolerant once established. To accommodate both:

• Water deeply but infrequently, focusing extra moisture around hydrangeas during dry periods
• Apply a 2-3 inch layer of mulch to help retain soil moisture and reduce competition
• Consider installing drip irrigation to provide targeted watering where needed

Fertilizing

Both plants benefit from similar fertilization practices:

• Apply a balanced, slow-release fertilizer in early spring
• Top dress with compost annually
• Avoid high-nitrogen fertilizers that may promote lush foliage at the expense of flowers
• For hydrangeas that change color based on soil pH, adjust soil amendments accordingly if you’re targeting specific bloom colors

Pruning

Pruning requirements differ between these plants:

• Cut back herbaceous peonies to the ground in late fall after frost has blackened the foliage
• Leave tree peony stems intact, removing only dead or damaged wood
• Prune hydrangeas according to their specific type (mophead, lacecap, panicle, etc.) as pruning requirements vary significantly
• Always sanitize pruning tools between plants to prevent disease spread

Pest and Disease Management

Both plants can experience similar issues:

• Monitor for powdery mildew, which can affect both plants
• Ensure good air circulation to reduce disease pressure
• Remove and dispose of any diseased foliage promptly
• Apply preventative fungicides if your garden has a history of fungal problems

Recommended Varieties for Companion Planting

Some varieties of peonies and hydrangeas pair particularly well together:

Peony Varieties

• Sarah Bernhardt – A classic pink peony with large, fragrant double blooms
• Festiva Maxima – White with crimson flecks, highly fragrant
• Karl Rosenfield – Vibrant red double flowers
• Bartzella – An intersectional peony with large yellow blooms and extended flowering period

Hydrangea Varieties

• Annabelle – A smooth hydrangea with large white blooms that provide a perfect leafy backdrop for peonies

Companion Plants to Consider

To enhance your peony and hydrangea garden, consider incorporating these additional companion plants:

• Clematis – These climbing vines provide vertical interest and can bloom simultaneously with peonies
• Hostas – Their attractive foliage complements both plants and thrives in similar conditions
• Astilbe – Feathery plumes that add texture and thrive in the partial shade conditions hydrangeas prefer
• Daylilies – Low-maintenance perennials that bridge the bloom gap between peonies and hydrangeas
• Ornamental grasses – Provide textural contrast and movement in the garden

Frequently Asked Questions (FAQs)

Q: How far apart should I plant peonies and hydrangeas?

A: Plant peonies and hydrangeas at least 3-4 feet apart to prevent competition for resources and ensure adequate airflow. Consider the mature size of your specific hydrangea variety, as some can grow quite large and potentially overshadow peonies if planted too closely.

Q: Will hydrangeas overshadow my peonies?

A: This depends on the varieties you choose. Larger hydrangea varieties should be planted behind peonies to prevent overshadowing. Since peonies bloom earlier than hydrangeas, they typically have time to display their flowers before hydrangeas leaf out fully.

Q: Can I grow both plants in containers?

A: While both can be grown in containers individually, it’s less common to grow them together in one container due to the space hydrangeas require. If attempting container planting, choose a compact hydrangea variety and a large container that can accommodate both plants’ root systems.

Q: How do I prepare the soil for planting peonies and hydrangeas together?

A: Amend the soil with plenty of organic matter such as compost or well-rotted manure. Ensure good drainage, as both plants dislike waterlogged conditions. Test your soil pH and adjust according to the specific hydrangea color you desire if growing a variety with color that changes based on soil pH.

Q: Why aren’t my peonies or hydrangeas blooming?

A: Several factors could cause blooming issues. For peonies, planting too deeply, insufficient sunlight, or recent division can affect flowering. For hydrangeas, improper pruning (cutting off flower buds), insufficient sunlight, or late spring frosts damaging buds are common culprits. Both plants may also skip blooming if over-fertilized with high-nitrogen fertilizers.

Creating a garden that combines peonies and hydrangeas offers the best of both worlds – the spectacular but fleeting beauty of peony blooms followed by the long-lasting display of hydrangea flowers. With their complementary growing habits and sequential blooming periods, these classic garden plants create a partnership that provides beauty throughout the growing season with minimal maintenance once established. Whether you’re designing a new garden or looking to enhance an existing one, this perfect pairing deserves consideration in any flower garden.
