Britain’s most common wild flowers are latest species to disappear from countryside

Even the commonest wild flowers are disappearing from the countryside, a new analysis of Britain’s biggest wild plant survey has shown.
Sites which should hold species typical of their habitat, such as scarlet pimpernel in cornfields, or primrose in woodlands, are increasingly being found with none of their characteristic plants. Although concern has long been expressed that some of Britain’s rare flowers, such as meadow clary and corncockle, are being pushed to the edge of extinction by intensive agriculture, there has been much less focus on common species, some of which may be traditionally thought of as “weeds”.
But the fact that common plants are also disappearing is being vividly demonstrated by the annual Common Plants Survey (CPS) run by the wild flower charity Plantlife.
