Paeonia 'Dinner Plate'

Paeonia ‘Dinner Plate’ does exactly what it says on the tin—this is a peony grown for enormous, sumptuous blooms that can be truly plate-sized when fully open. Expect big, showy flowers in soft, romantic pink tones with layers of ruffled petals that make a real statement in the late spring/early summer garden. It’s a brilliant choice if you want that classic, luxurious peony look for borders and cutting gardens, and the blooms are fantastic for vases (you’ll only need a few stems to make an arrangement!).

The plant forms a strong clump of fresh green foliage that stays attractive well after flowering, adding structure through summer. As with all herbaceous peonies, ‘Dinner Plate’ is long-lived and will happily settle in for years—often improving with bigger clumps and more flowers each season, as long as it’s planted at the correct depth and left undisturbed.

Planting Instructions

When to Plant:

Plant bare root peonies in autumn (best) or through to early spring, while dormant. Avoid planting when the ground is frozen or waterlogged.

Where to Plant:
Choose a sunny position (or light shade) with fertile, well-drained soil. Peonies dislike sitting in wet ground and prefer to be left undisturbed once established. Ideal for mixed borders, cottage gardens and cutting gardens.

How to Plant:

• Depth: Plant so the ‘eyes’ (buds) sit just 2–3 cm below the soil surface. Planting too deep can reduce flowering.
• Spacing: Space 80–100 cm (32–40 inches) apart to allow good air circulation and room to mature.
• Soil Prep: Dig a generous hole and mix in well-rotted compost or manure. In heavy soils, add grit to improve drainage.

Watering:
Water well after planting. Keep the soil lightly moist while establishing, then water only during prolonged dry spells. Avoid waterlogging, especially in winter.

Aftercare Tips:

• Mulch in spring with compost, keeping it away from the crown.
• Because the blooms are so large, provide discreet support or a peony ring if needed—especially in wet weather.
• Deadhead after flowering, but leave the foliage to feed the plant for next year.
• Cut back foliage in autumn once it dies down and dispose of it to keep plants healthy.

Top Tip:
For the best vase life, cut stems when buds are just starting to open and feel like a soft “marshmallow”. And remember—planting depth matters: peonies planted too deep can be slow to flower.
