English BlueBells

I've posted this pic cause I read somewhere that they are like dying out and that Spanish blue bells are taking over. I took this cause on my way back from school I fun many of these in a garden and coming out of the holes in the fence. How you can tell which one is a English bluebell is that if the top of the bluebell is floppy and the flowers are on one side and looking dopey. And Spanish bluebells are upright and the flowers are all around the stem.
