I wasn't sure about including this one which we found at the side of a road until I looked in Stace a where he says it is naturalised on roadsides and rough ground on Guernsey! This is a southern European introduction which is only found in mostly around coastal southern England but which has been naturalised in odd places throughout the rest of England. There are a very few sites in Wales, Scotland and Ireland as well.
