Colours! The most beautiful of buds – an apple bud in my garden changes colour from red to rosy after a few days. Why? It then explodes into a beautiful pale rosy flower.

It is pale green, but moving along its surface the colour changes quite abruptly to an extraordinary vibrant red. The apple looks quite different when lit by full sunlight, or when placed in the shade
