ANSWER (subsequently added to this post to facilitate the “search” function for these images): Tall bellflower (Campanulastrum americanum)
I think it’s tall bellflower Campanulastrum americanum
I think it is the bluebell flower. Campanula Rotundifolia
Joyce, you are correct. This is Tall bellflower (Campanulastrum americanum). The flower’s style which extends well beyond the petals is one of its distinguishing characteristics. Josey, your guess was a good “runner-up” possibility.
