This will be a familiar plant to many of you, and it is not a rare species, but it often indicates old or undisturbed pastures. It is found on limestone grassland and its most common habitat these days is churchyards. It is not to be confused with Greater Plantain, whose leaves are similarly wide (but which have a stalked stem). Hoary Plantain leaves are generally softly hairy and rather grey-green and have long silky hairs in the rosette centre and the flowering head has an attractive fringe of pink anthers on long stalks (which Greater Plantain does not have).
