Eden Brothers Dahlia Tubers

Dinnerplate dahlias are a specific classification of dahlia known for their massive, oversized blooms that can reach 8 to 10 inches or more in diameter. This variety is prized for its dramatic, show-stopping size, making them ideal for focal points in a garden or large-scale floral arrangements.

While these dahlias thrive in garden beds, they can be grown in large containers provided the pot is at least 12 to 16 inches deep and has excellent drainage. Ensure the container is placed in a spot that receives full sun for the best bloom production.

These dahlias are hardy in zones 8 through 11. If you live in a colder climate, you can still enjoy them by treating them as annuals or by digging up the tubers in the fall after the first frost and storing them in a cool, dry place over the winter to replant in the spring.

Once established, this mix provides a consistent display of flowers from summer through late fall. Regular deadheading—removing the faded blooms—will encourage the plant to direct its energy into producing new flowers throughout the season.

Yes, because dinnerplate dahlias grow up to 36 inches tall and produce heavy, large blooms, they often require staking to keep them upright. Installing a support stake or cage at the time of planting prevents the stems from bending or breaking during heavy rain or wind.

They are quite straightforward. Simply plant the tubers 2 inches deep in well-draining soil during the spring once the danger of frost has passed. Space them 12 to 18 inches apart to ensure they have enough airflow and room to reach their full mature height.
