Any Ideas?

I saw masses of these pretty daisy-like flowers in the gardens of Ely Cathedral yesterday but I’m not sure what they are. Osteospernum? Any ideas?

Very pretty. My iPad plant finder is telling me that it might be Confused Michaelmas daisy!!

@wakelys I agree that there is a similarity but I have MD in my garden and they have very distinctive leaves.

Whatever they are (and I have no idea), they are incredibly pretty. Fav
