Black Jack Cactus Dahlias produce massive, 8-inch flowers that have a deep red, almost black eye that fades into a lighter shade of red. The reddish-green foliage complements the blooms and adds even more depth into the beautiful dahlia! Black Jack ships as a bare root. We like growing from bare roots because they establish quickly, become twice the size of a potted plant in the first season, and eliminate the need for plastic pots (a win for the environment).
Dahlia Companion Plants: Geranium, Salvia
Black Jack Dahlia Plant Care Instructions: Plants should only be watered if there is no rain for a week or if the plant starts wilting. If you want more blooms, snip off the top leaf stem once there are at least 3-4 sets of sets of leaves growing. In the fall, after frost has turned the foliage brown, the tubers should be dug back up and stored for the winter.
