so it goes
Brassica oleracea var. acephala — Although more highly developed forms, such as cauliflower, broccoli, and head cabbage, have been produced in the last two thousand years or so, the kales and collards have persisted, although primitive, because of their merits as garden vegetables. These leafy nonheading cabbages bear the Latin name Brassica oleracea variety acephala, the last term meaning “without a head.” They have many names in many languages, as a result of their great antiquity and widespread use. Kale is often called “borecole,” and in America collards are sometimes called “sprouts.” “Kale” is a Scottish word derived from coles or caulis, terms used by the Greeks and Romans in referring to the whole cabbagelike group of plants. The German word Kohl has the same origin. “Collards” is a corruption of coleworts or colewyrts, Anglo-Saxon terms literally meaning “cabbage plants.” — Our Vegetable Travelers
