Growing dahlias from seed can be very exciting. As dahlias being grown from seed will be completely random and can be any size, height, shape, or color. Consider this similar to growing wild flower seed. Although 90%+ of the successful seed in the mix will grow to be collarette (open-centered)...
Resources
Dahlias are grown from tubers (similar to a bulb, but thin-skinned like a potato). Plant tubers in the springtime, about the same time as you would your vegetable gardens or when the ground is warm enough to work up and play in daily. Plant them in a full sun location (giving them 6-8 hours of direct sunlight) and enjoy blooms all summer long. They will bloom and provide you with color and abundant flowers for cutting and enjoying throughout the summer.
The more you cut a dahlia plant, the more it will bloom. Most cut dahlias will last up to 5 days once cut and treated.
Dahlia tubers (and any items included in the same order) ship from March through May. Gift Certificates, Mercantile items, and Garden Supplies, ship year-round.
