70 days. Rubybor is a true dual-purpose breakthrough, the first kale to win an AAS Gold Medal award in both the edible and ornamental trials. Deep, richly purple, finely frilled leaves form upright, dense, uniform plants with a compact habit reaching 36 inches tall and 24 inches wide. As temperatures drop, the purple color intensifies, becoming even more vivid and eye-catching. Beyond its beauty, Rubybor delivers serious harvests. In trials, the plants produced up to twice the leaf weight of other red kales, offering a long, continuous supply from spring to frost. The tender, non-bitter leaves are excellent fresh, hold their tenderness even as the plant remains in the field, and also stand up well to cooking.
