Brassica napus subsp. napus
Rapeseed or oilseed rape is easily recognisable by its bright yellow flowers. Originally probably from the Eastern Mediterranian region, it is known to have been cultivated in other parts of Europe since 2000 years before our time. Today, it is the third-largest source of vegetable oil and the second-largest source of protein meal in the world. It has long been used as cooking and lamp oil, today it still used as edible vegetable oil, but also animal feed and even as the basis for biodiesel.
Rapeseed (or even just rape) gets its somewhat unfortunate name from the Latin word for turnip, rāpa or rāpum. The rapeseed is one of two subspecies of Brassica napus, namely Brassica napus subsp. napus. The other, B. napus subsp. rapifera, is the yellow (as opposed to the better know white) or Swedish turnip, which is also known as rutabaga (which appears to be its North American name).
Rapeseed is known to escape cultivation and settle in roadside verges and waste grounds. However, it seems to stay in the vicinity of the cultivation and I have not found any indication of it being invasive anywhere.
