Has it been determined why some flowers such as the cleome Have such intricate designs?

Question

I've been studying flowers over the past few years as I photograph them and find it fascinating the way they are so individual and sometimes very ornate. The cleome is one I've been studying lately and wonder why it has so many and varied parts. Another one is the columbine flower. It reminds me a little bit of a rocket when viewed from the side with those trailing "tails". I'm wondering if there is a purpose to each part or whether it's similar to human eccentricities in fashion, especially women's. Can these seemingly disparate patterns be connected?

Love Steve's answer. To add to it, it's also about competition. There are only so many pollinators out there and plants have to compete for them. There are orchids that mimic female wasps and males pollinate them while trying to mate with them. Some flowers have IR reflecting patterns on them that are invisible to us but make insects go "Ahh!!!".

Answer 2

The evolution of plants (as well as animals) is fascinating.  For millions of years plants have adapted in order to survive.  They produce brilliant flowers as to attract bees and butterflies and insuring reproduction and establishment.  Trees producing wonderful red fruit which once consumed by a primate, insures the seed to be carried -off, eliminated, and germinating into another tree.  It's amazing if you really think about it- not to mention question creation
