Going by this clue, I too checked for Red Flare.... rubra.... of course, Nymphaea. I have the caerulea [blue] which is yet to mature fully. I have not edited the picture I posted above and so the colour you see is true..hoping the computer monitors present it right. Mine does. I have not checked if it opens at night. Have to remember to go out and check.

This is on the first day I saw. It was already closing up before I went to work.
