colza (KOL-zuh, KOHL-zuh) - n., oilseed rape.
That is, another name for one of the rapeseed plants that produce rapeseed oil or canola oil -- specifically, Brassica napus subsp. napus. (Canola is made from this, Brassica rapa subsp. oleifera, and Brassica juncea.) The name is from French, from Dutch koolzaad, from kool, cole/cabbage + zaad, seed.
