January King Cabbage
I am so happy to bring you this outstanding winter cabbage. January King is extremely hardy, like the savoy cabbages, but with smoother, thicker leaves, only slightly savoyed. Develops some red or purple coloration in cold weather. Intended for planting mid to late summer, for winter meals from December to March. In very wet winters, heads will last better under cover.

In addition, the gardener can use a number of strategies to enhance survival: Planting in a well-drained location, making windbreaks, mulching, providing shelters such as coldframes, and refraining from heavy fertilization in late summer will all enhance winter survival.
