For grand summer plants you won't go wrong with our Dinner Plate Dahlias, where size meets spectacle. At Peter Nyssen, we present a curated selection of these majestic tubers for sale. Create a garden adorned with the grandeur of oversized blooms. Flower heads filled with ornate florets reaching over 20cm wide and more. 

Dinner Plate Dahlias live up to their name, boasting blooms that stretch up to a dinner plate's size, creating a captivating focal point in your summer garden. With a diverse palette of colours and textures, these dahlias command attention and add an extravagant touch to your floral ensemble.

This category includes dahlias from decorative and cactus classes, but plant them and you're sure of a dazzling show. These enormous blossoms have many different forms including a classic, decorative form with neatly cupped petals in Café au Lait or Thomas Edison or more pointed petals such as in Show and Tell, or crazy and flounced as in Penhill Dark Monarch.

Dahlia care for giant blooms

• Choose a sunny spot with well-draining soil and plant the tubers about 15 cm deep, allowing ample space between each tuber for their majestic blooms. 
• Water generously after planting to awaken these giants from their slumber.
• Caring for your Dinner Plate Dahlias requires a keen eye but they are worth the extra care. 
• Keep the soil consistently moist, ensuring they receive at least 6-8 hours of sunlight daily. 
• Sturdy support is essential, as these magnificent blooms can grow tall and the flowers can be heavy.
•  Regular deadheading and removing spent blooms will encourage continuous flowering throughout the summer, ensuring your garden is adorned with regal beauty.

When is the best time to plant Dinner Plate Dahlia tubers?

Plant your Dinner Plate Dahlia tubers in late spring, after the threat of frost has passed. This ensures they have ample time to reach their full majestic potential during the summer months. You can start the tubers early in pots kept in a greenhouse or cold frame to give them extra growing time.

Can Dinner Plate Dahlias be grown in containers?

While it's possible, these giants are best suited for garden beds where they can truly unfold their grandeur. Ensure the container is large enough to accommodate their substantial size and provide sturdy support. A pot of around 50litres would be just big enough (in our experience)

What are good companion plants for Dinner Plate Dahlias?

Create a harmonious garden symphony by pairing Dinner Plate Dahlias with tall companions like Delphiniums, Cannas, and Cosmos. The contrasting heights and textures will enhance the regal atmosphere.

Are there alternatives to Dinner Plate Dahlias?

If you're looking for alternatives, explore other dahlia varieties like Café au Lait for a softer touch or Karma series for a variety of colors. Anemone and Gladiolus also make excellent choices for a garden with a commanding presence.
