Yes, another sunflower shot. They are looking east, incidentally, away from the setting sun. And, yes, they look east all day and all night long. When I was a kid someone told me that they actually turned so they always faced the sun. That would be a form of heliotropism, so my high school biology teacher would say.
But sunflowers aren’t that ambitious.
