The pattern of these petals is stunning and reminds me of an interesting thing, which I hereby present to you as my Fact Of The Day: some flowers have markings on their petals which we can't see, because they reflect UV light that our eyes don't pick up. Certain pollinating insects can see into different spectral bands than humans, and the flowers' colouring reflects this; sometimes what appears to us as a fairy unexciting bloom looks quite different if you use a camera which is able to record ultra violet or infra red light. There's a really nice website here which has photos of different flowers shown as they normally appear to us, and coloured to show the UV patterns and fluorescence which we can't see. Some of my favourite examples include this picture, which I think is featured in Richard Dawkins' book The Greatest Show On Earth, this very jazzy example, and this rather dramatic bloom, which clearly shows the "bulls-eye" pattern that a lot of UV-patterned flowers exhibit.
So next time you see a rather plain and insipid bouquet, just remember: perhaps it's your eyes and not the flowers which are at fault...
