The feared fairy bell and impending death
According to English folklore, Bluebells were often used to call fairies…If you “rang” a bluebell like you would any normal bell, it was believed fairies would come to you. But fairies are notoriously dangerous bargainers and the need to call fairies for aid must be great to risk the summons.
There is another folklore that states if you hear a bluebell ring, somebody close to you will die. Bluebells growing en masse in a field were best avoided.
