Kale (//), or leaf cabbage, belongs to a group of cabbage (Brassica oleracea) cultivars grown for their edible leaves, although some are used as ornamentals. Kale plants have green or purple leaves, and the central leaves do not form a head (as with headed cabbage). Kales are considered to be closer to wild cabbage than most of the many domesticated forms of Brassica oleracea.
From Middle English cale or cal (northern dialect), variant of col (“cole”), from Old English cāl, cāul, cāwel, from Latin caulis. Compare English cole, Icelandic kál (“cabbage”), German Kohl (“cabbage”). Doublet of caulis.
