I know you must be bored with my raving about the garden in the old folks home... especially since this is the second one in same day, BUT..
After I raved, and posted a picture of one specific bloom this morning, I went back in the afternoon. All those smaller blooms you see in the picture, had expanded...in a few hours.. and they ALL looked sensational and large. Our prize bloom was surrounded with like blooms. Strange how fast things can change with plants.
I have known for a long time that Sunflowers turn during the day to follow the sun, but I had not known that roses can grow and expand in the course of the day. Live and Learn.
