Don't think that the blue one is a campanula...just checked some
flower pictures and they all look rather different.
As for the greenery I agree - it should be Eucalyptus Jiffymouse. My sister once had
flowers delivered for valentines day - they were really beautiful and we liked the greenery and ended up calling the
flower shop to find out what it was -> Eucalyptus Jiffymouse, so I am pretty sure on that one.
The bouquet is really gorgeous. Do you know where it is from?
