Trees for Autumn Colour
The beauty of the leaves of many plants and trees masks an extraordinary powerhouse of chemistry. Each thin leaf has a complex structure of vessels and cells, designed to capture the energy of the sun and to harness that energy for growth and survival.
The leaves use the sun's energy to make sugars out of water and carbon dioxide from the air. This process uses chlorophyll, the pigment that gives leaves their green colour. In mid-summer this is in full swing, and the leaves need plenty of the green chlorophyll. However, as autumn approaches the process tails off, chlorophyll is used up and not replaced. As this happens, other pigments which may be present in the leaves begin to show more prominently. Also, other pigments may be produced by the breakdown of chemicals in the leaves. It is the interaction of all these colours within the leaf which lead to the breathtaking autumn displays that some trees give. And it is breathtaking. If single leaves of a few good subjects are examined, you will see brilliant colours from bright yellow, through orange and salmon, pink, bright red, deep red, purple.
The formation of these autumn colours in the leaves may be affected by the weather. It is said that the best colours occur when there is a sunny but not too warm spell in autumn, with cold but not frosty nights. However, some varieties produce a great show every year, and the autumn display is the crowning glory of many parks and forests. With a little thought and planning even a small garden can take part.
