Identification: What is this flower?

My mom received a bouquet of flowers from her beau and asked me to identify them. I've tried my hardest, but I simply can't figure out what they are. I realize they may be some weird variety of flower, but even a generic name would make her happy.

Thanks!

 

Looks like Campanula medium, Canterbury bells.

 

Wonderful, thanks! I looked up some images of them, they look just like canterbury bells!
