Peonies: The Queens of the Summer Garden

Few plants can rival the beauty, elegance and sheer presence of a peony in full bloom. With their enormous, fragrant flowers and luxurious petals, peonies have long been regarded as the aristocrats of the garden. Their spectacular display may be relatively short-lived, but what a display it is!

Whether planted in a cottage garden border, a formal garden scheme or a large patio container, peonies reward gardeners with some of the most breathtaking flowers of late spring and early summer.

At our garden centre, peonies are among the most admired plants by visitors, and it’s easy to see why. Their romantic blooms, exceptional longevity and ease of care make them a favourite for gardeners of all experience levels.

When Do Peonies Look Their Best?

Peonies typically flower from late May through to June, depending on the variety and weather conditions.

The arrival of peony season is often considered one of the highlights of the gardening year. Large buds slowly swell before suddenly bursting open into magnificent blooms that can measure up to 20cm (8 inches) across.

Flower colours include:

🌸 Soft blush pinks
🤍 Pure whites
💗 Deep rose pinks
❤️ Rich crimson reds
💛 Cream and buttery yellows

Many varieties are highly fragrant, filling the garden with a sweet, delicate perfume that attracts pollinators and delights gardeners alike.

A mature peony in full flower can become the centrepiece of an entire garden border.

How to Grow Peonies Successfully

Choose the Right Position

Peonies thrive in:

☀ Full sun or light partial shade
🌱 Fertile, well-drained soil
💨 Sheltered positions away from strong winds

For the best flowering, aim for at least six hours of direct sunlight each day.

Planting Peonies

The most common reason peonies fail to flower is planting them too deeply.

The crown or buds should sit only 2-3cm below the soil surface. Planting deeper than this often results in healthy foliage but few flowers.

When planting:

• Improve the soil with compost or well-rotted organic matter
• Water thoroughly after planting
• Leave enough space for future growth

Peonies dislike disturbance, so choose their position carefully. Once settled, they prefer to stay where they are.

Caring for Peonies

Fortunately, peonies require very little maintenance.

Watering

Water regularly during dry periods, particularly during their first year after planting.

Established plants are surprisingly drought tolerant but will always appreciate a good soak during prolonged hot weather.

Feeding

Apply a balanced fertiliser in spring as new growth emerges.

Avoid excessive nitrogen-rich feeds, which can encourage leafy growth at the expense of flowers.

Supporting Flowers

Large double-flowered varieties can become heavy when in bloom.

Peony supports or discreet plant rings can help prevent stems from flopping, particularly after heavy rain.

How to Get More Flowers

To maximise flowering:

🌿 Plant in a sunny position
🌿 Avoid planting too deeply
🌿 Feed annually in spring
🌿 Remove spent blooms promptly
🌿 Avoid moving established plants unnecessarily

Patience is important too. Newly planted peonies can take a couple of years to settle before producing their best displays.

What To Do When Peonies Have Finished Flowering

Many gardeners wonder what to do once the spectacular flowers fade.

The good news is that peonies continue to contribute to the garden long after flowering has finished.

Deadheading

Remove spent blooms by cutting back to a healthy leaf.

This prevents the plant wasting energy on seed production and helps keep plants looking tidy.

Leave the Foliage

Resist the temptation to cut the plant down.

The foliage continues photosynthesising throughout summer, storing energy for next year’s flowers.

Healthy green foliage can provide an attractive backdrop in mixed borders for months after flowering.

Autumn Care

In autumn, herbaceous peonies naturally die back.

Once foliage yellows:

✂ Cut stems back to ground level
🍂 Remove any fallen leaves
🌱 Apply a mulch around the plant (but not directly over the crown)

This helps maintain plant health and reduces the risk of disease.

Peonies as Cut Flowers

Peonies make some of the finest cut flowers available.

Cut stems when the buds feel soft, like a marshmallow, but before they fully open.

A vase of freshly cut peonies can fill a room with fragrance and provide an elegant display for over a week.

A Timeless Favourite

It’s easy to understand why peonies have been cherished by gardeners for centuries. Their magnificent blooms, wonderful fragrance and exceptional longevity make them one of the most rewarding plants you can grow.

If you’re looking to add beauty, elegance and a touch of luxury to your garden, few plants can rival the unforgettable charm of a peony.
