Collards, also called collard greens or borekale (Brassica oleracea Acephala Group), are various loose-leafed cultivars of the cabbage plant. The plant is grown for its large, dark-colored, edible leaves and as a garden ornamental, mainly in Brazil, Portugal, the Southern United States, many parts of Africa, Montenegro, Spain and in Kashmir as well. They are classified in the same cultivar group as kale and spring greens, to which they are extremely similar genetically.
