Not only are flowers fascinating, but they are informative too. As Steven Pinker acknowledges in the August 2007 issue of Popular Photography, ..."they (flowers) are excellent clues to a plant's species" and "they are forerunners of fruit." "...a brain that takes pleasure in looking at flowers is a brain that is going to soak up ecologically useful information, and have a survival advantage over brains that just like to look at rocks or dirt or sand or sky. Photography is a way of pressing that pleasure button". And Debbie Mandel adds that "The flower as symbol of a blossoming woman is archetypal in literature" and therefore it satisfies our romantic hunger as well. Leon Hoffman has some interesting words regarding sex and flowers, but I'll let you find the issue of Popular Photography and read them for yourself. lol
You will be led to the knowledge of the internal things which are invisible to you, by the external things which you see before you. . . . Even so then, we can represent to ourselves in thought the Author of all that is, by contemplating and admiring the (visible) things which He has made, and ever brings into being.
