- A winter radish with a black color that takes longer to mature, and has more heat than most radishes.
50-70 days. This winter radish is slower to mature than most regular radishes. Plant them in the fall and harvest as needed. They have a great zippy flavor, a bit hotter than most. Large greens. In mild climates, they are traditionally grow over winter like Asian radishes. Can also be planted early in the spring. Attractive black skin with pure white flesh. Very good keeper.
