Kale is a highly nutritious, fast-growing winter crop that produces leaves that can be large and flat or with tightly curled or fringed edges. This species is known scientifically as Brassica oleracea var. sabellica (acephala Group). Commonly as kale, the leaves can be green or purple depending on the variety. Tronchuda is a loose leaf kale cultivar with a good flavour. The name means without head which is why you don't get a head of Kale.
