The Dahlia ‘White Perfection‘ is a spectacular dinner plate variety known for its massive, pristine white blooms that reach up to 10 inches (25 cm) in diameter. Growing up to 4 feet (1.2m) tall, it blooms continuously from mid-summer through early fall and thrives in full sun and well-drained soil. [1, 2]
Key Growing & Care Guidelines
- Planting: Plant the tubers (bulbs) in the spring after all danger of frost has passed. Bury them about 4 to 6 inches deep with the “eye” facing upwards. [1, 2]
- Support & Maintenance: Because the blossoms are incredibly heavy, the tall stems require staking or a tomato cage to prevent snapping. Deadhead spent flowers and disbud surrounding flower clusters to encourage even larger blooms. [1, 2]
- Overwintering: In cooler climates (USDA zones below 8), you must dig up the tubers in the late fall, let them dry, and store them in a cool, dry, frost-free location for the winter. [1, 2, 3, 4, 5]
