Brassica napus, Napobrassica Group
Rutabagas, also known as Swede turnips or simply Swedes, are an often over-looked table vegetable in our modern western diet. They appeared in Europe in the Middle Ages and are reportedly the result of a cross between cabbage and turnips.
They can be boiled and mashed as a potato substitute for those on low starch diets. They are cold tolerant and except in areas of extreme cold, can be left in the ground over winter.
