Rutabaga or
swede is a root vegetable, a form of
Brassica napus. Other names include
Swedish turnip,
neep (Scots), and
turnip. However, elsewhere, the name "turnip" usually refers to the related white turnip. The species
Brassica napus originated as a hybrid between the cabbage and the turnip. Rutabaga roots are eaten as human food in various ways, and the leaves can be eaten as a leaf vegetable. The roots and tops are also used for livestock, fed directly in the winter or foraged in the field during the other seasons. Scotland, Northern and Western England, Wales, the Isle of Man, and Ireland had a tradition of carving the roots into Jack-o'-lanterns at Halloween.
