Bougainvillea with two different coloured flowers.

This bougainvillea is growing in front of our post office and as I walked past it this evening on my way home from work the sun was hitting it at a lovely angle and I couldn't resist taking a photo of it.
I love the two different colours of the flowers, it's just beautiful. As you can see I have inserted a photo of the bush in the top corner so you can see how the plant grows.
