This is a very nice treatment of capturing the “Blue Moon Flower.” This picture is most likely taken in the morning facing the the east. As moon flowers close during the day and are rarely visible in full sun light. The thicket behind this particular group of flowers provides adequate shade to allow the flowers to remain open. As a vine plant that is particularly fond of fences and narrow trunked trees, the flowers on the eastward facing side of the fence would be already closed for the day.
