Can you name these tulips please? Also, what are the blue flowers interspersed between them?
It is the first photo on the giverny link.
Here is a link that might be useful: Monet's garden
Pretty hard to give a specific ID just based on the photo but one can make suggestions for tulips of similar coloring.
The ones in the back look like 'Pink Impression'. In the foreground, the lighter purple tulips could be any of a dozen or more different varieties - 'Purple Lady', 'Purple Rain', 'Singapore', 'Othello', 'Passionale', etc. The darker purple variety could be 'Negrita' or 'Queen of the Night'.
And it's almost impossible to discern what the blue flowers are......much too small a photo to work from. Need a close up!! But you could get the same effect by interplanting with muscari or blue hyacinths. But they look more like blue flowered pansies to me.
The blue flowers appear to be pansies. I have seen them in other photos of the Clos Normand. As gardengal48 says there are several different tulips in the picture and it is the blending of the colours which is part of the magic of the gardens. I have checked several French sources for a list of the bulbs used and can only find general references to 'tulips', even on the Giverny official list of plants. The names gg gave would achieve a similar effect.
