Park Seed Dahlia Otto's Thrill Bulbs

This is a true dinnerplate dahlia, producing massive, symmetrical double blooms that typically measure between 8 and 10 inches across.

While they thrive in garden beds, 'Otto's Thrill' can be grown in large containers. Ensure your pot is deep and wide enough to support a plant that reaches 4 feet tall and provide a sturdy stake to prevent it from tipping over.

Yes, the key is regular harvesting. The more you cut the stems for floral arrangements, the more the plant will be encouraged to produce new blooms. Keep them well-watered and ensure they receive full sun.

Dahlias are tender perennials hardy only in USDA zones 9-11. If you live in a colder region, you will need to dig up the tubers in the fall after the first frost and store them in a cool, dry place over the winter before replanting in the spring.

For the best airflow and growth, space your bulbs 18 to 24 inches apart. This spacing helps prevent foliage diseases and ensures each plant has enough room to reach its full 4-foot height.
