Know before you buy
These are classified as 'dinner plate' dahlias, meaning the individual blooms can reach an impressive 8 inches in diameter.
While the 'Great Hercules' features sturdy stems, their height of 36-44 inches and large flower heads mean they may benefit from staking, especially in areas prone to strong winds.
Yes, their upright growth habit makes them suitable for large containers, provided the pot has excellent drainage and is deep enough to accommodate the 3-4 inch planting depth.
In zones colder than 8, the tubers will not survive the winter in the ground. You should dig them up after the first frost and store them in a cool, dry place until the following spring.
For the best performance and most vibrant color, plant them in a location that receives full sun. They can tolerate partial shade, but you may see fewer blooms as a result.
Absolutely. Their long, sturdy stems and dramatic size make them an excellent choice for cut flower arrangements that bring vibrant color indoors.
