Brassica napus subsp. oleifera Oil-seed Rape

Brassica napus subsp. oleifera, Oil-seed Rape, is frequently cultivated as a crop for its oil-rich seeds. It often escapes from cultivation and has become a  common sight along roads throughout Britain. It is easily confused with Wild Turnip (Brassica rapa subsp. campestris) and Turnip-rape (Brassica rapa subsp. oleifera) which is also cultivated for its oil-bearing seeds. One of its distinctive features is that the flower buds overtop the open flowers in the terminal inflorescence. Oil-seed Rape has a scattered, casual distributionin West Glamorgan.
