I'm always quite fascinated by the way trees do autumn. These 3 trees above are all next to each other in a street around the corner from me. Yet even thought they are the same type of tree, and getting similar amounts of sun, warmth & water, they vary in their states of autunmness (I know it's not a word, but I'm sure you know what I mean).
One is full of coloured leaves, one is only just starting to change colour & the other has only a handful of leaves left on it's branches. Interesting, don't you think?
