It seems that flowers haven't always existed, but they started to appear many millions of years ago. I have no idea why. Weirdly, broccoli is a flower, and roses are related to apples, cherries, peaches, plums, raspberries, pears and almonds. Again, I have no idea how or why. Anyway, here's some pretty flowers that I've found in odd situations, mainly, as always, in urban situations.
