Jackson & Perkins Dahlia Otto's Thrill

These dinnerplate dahlias are impressive, typically producing double blooms that measure between 8 and 10 inches in diameter. Their size makes them a standout choice for dramatic garden displays and large-scale floral arrangements.

Yes, 'Otto's Thrill' is well-suited for container gardening. Because the plants reach a mature height of 48 inches, ensure you use a large, sturdy pot that can support their upright, clump-forming habit and provide enough room for root development.

Since 'Otto's Thrill' is a tender perennial hardy only in zones 9-11, you will need to lift the tubers from the ground after the first frost in colder regions. Clean them off, let them dry, and store them in a cool, dry place over the winter to replant the following spring.

For the best results and the most prolific blooming, plant these dahlias in a location that receives full sun. This ensures the stems remain strong and the flowers develop their full, vibrant color.

You should space the bulbs 24 inches apart. This spacing allows for proper airflow, which helps prevent disease and gives each plant enough room to reach its full mature spread of 24 inches.
