Rapeseed is a bright-yellow flowering which also known as rapa, rappi or rape. Currently, most of rapeseed is grown for the production of animal feeds, edible vegetable oils, and biodiesel. Wild seeds also contain high levels of glucosinolates. Rapeseed produces great quantities of nectar, and honeybees produce a light-colored but peppery honey from it.
