Some of the most beloved British summer wildflowers are in fact, the most endangered, according to the botanical charity Plantlife International.
Researchers say arable plants, a group which includes poppies and buttercups, have shown the greatest decline of any type of British flora.
BBC environment correspondent Sarah Mukherjee says scientists are worried that many of these plants - once considered weeds - have declined to the point of extinction.
Modern industrial farming techniques have now pushed many arable "weeds" close to extinction.
