I think this pic is a little too “warm”. Tough. This is such an interesting flower. Have some pink ones, too. Only open for part of the day. Seems random to me (but I know it isn’t). Think opening has as much to do with sunlight (vs. clouds) as it does time of the day. Bees love it, but they’re heavy enough to move the blossoms when they latch on. Really a neat flower. One I haven’t quite figured out yet.
