This is tricky one as it's a view from under the flower - I wondered if it was a Buphthalmum, but the underneath looks different from the photos I've seen.
I'm trying to identify this so I can write something about it for a greeting card in a range we produce at work - but this one has me stumped!
I'm hoping someone more knowledgable will have an idea;-)

The only other picture in our library that I can find of this plant shows it to have long bare stems, if that helps.
