The top one is Madame le coultre, also known as Marie Boisselot - the other one, not too sure what that is, the reddish ones have a tendency to change colour after opening, often lightening up or fading. It looks awfully like Ville de Lyon, but its too early - that doesn't usually start till end of June.

Thank you bamboo that was very helpful. Think you are right with ville de Lyon. Name sounds familiar. It has bloomed early I think.
The white one is my favourite. Thank you so much.
