The photos below unfortunately don’t capture the dazzling, eye watering yellow of a field of rapeseed.
Europe grows up to 20 million tonnes of it each year and it is the third most popular oil in the world. It is very high in protein and is also used as an animal feed and biofuel.
It easy escapes fields and is along most major highways in England. It is a brassica and can look from a distance like broccoli that has bolted.
