Rutabaga — The swede, or (yellow) turnip (Brassica napobrassica, or Brassica napus var. napobrassica) is a root vegetable that originated as a cross between the cabbage and the turnip. Its leaves can also be eaten as a leaf vegetable.
The plant is believed to be a cross between the white turnip and the cabbage and to have originated in Europe during the Middle Ages. Rutabaga requires a cool growing climate. It is especially popular in northern Europe, as evidenced by its other common names: Swede, Swedish turnip, and Russian turnip. Its culture is similar to that of the TURNIP, although rutabaga takes 4 to 6 weeks longer to mature. The roots have a sweet flavor and store well; if kept cool and at high humidity, they may be used for several months. They are often treated with wax to prevent water loss during storage.
