Kale or borecole is a vegetable with green or purple leaves, in which the central leaves do not form a head.
It is considered to be closer to wild cabbage than most domesticated forms of vegetables.
The species Brassica oleracea contains a wide variety of vegetables, including broccoli, cauliflower, collard greens, and brussels sprouts. The cultivar group Acephala also includes spring greens and collard greens, which are similar genetically.
Pieris rapae is one of the best-known pests of the plant.
