Marsh bellflower is sort of the Rodney Dangerfield of bellflowers. Not very colorful, not very big, not very strong, it just doesn't stand out among its bellflower kin. But it does OK for itself. You're liable to see one here or there any summer you venture into a damp open area, particularly if it's a little basic, like (you guessed it!) a fen. Ives Fen Preserve, Lenawee Co MI, 7/25/15.
