Know before you buy
Each purchase includes 3 clumps of tubers, which are ready for immediate planting upon arrival.
Dahlias are perennial in zones 8-10. If you live in a colder climate, you will need to lift the tubers in the fall and store them in a frost-free location over the winter.
For optimal airflow and growth, space your tubers 18 to 24 inches apart. This allows enough room for their 36-inch spread.
Yes, the Optical Illusion Dahlia is an excellent choice for attracting bees and butterflies to your landscape throughout the summer and fall.
To encourage continuous flowering from summer through fall, be sure to deadhead spent blooms regularly. This prevents the plant from putting energy into seed production and redirects it toward new flowers.
Absolutely. Their large, 5-inch double blooms and unique quilled petals make them a standout choice for fresh-cut flower arrangements.
