Kale is sometimes used as an ornamental, but people mainly grow it for its edible leaves. The vegetable is sometimes referred to as leaf cabbage. They are also considered to be closer to wild cabbage than other cultivated types of cabbage. Kale can have either purple or green leaves and they don’t form a head like cabbage. The plant has a high tolerance for extreme weather and has its peak during the winter. Kale’s taste becomes sweeter after it survives the frost.
