Canola (which name comes from Canadian oil) and oilseed rape (traditional), is a member of the brassica (cabbage and turnip) family, was developed from rapeseed, an oilseed plant used since ancient times as a fuel. The word "rape" in rapeseed comes from the Latin word rapum meaning turnip. Mustard is also part of the same family. It is now used in food as well as a biofuel. It is common in fields in N America and Europe, flowering in late spring.
