In the Mediterranean region bladder campion (Silene vulgaris) is widely valued as a food [1]. Typically:
‘The following recipe was given to me in March 1994, with enthusiasm and relish, by a young hotelier at Platres, in the Trodos Mountains, Cyprus:
Take the tender tops (c. 4 inches) of young shoots of bladder campion, fry lightly for 1-2 minutes in a little oil, throw in some beaten
eggs – add a pinch of salt, serve with a slice of lemon.
He told us that bladder campion is cultivated locally for eating, and that                                                                                                        young  shoots of opium poppy                                                                                  [Papaver somniferum]                                                                                                    are similarly used’ [2].

Does anyone have any records of bladder campion being eaten in the British Isles?
