Is there anyone who does not love the display of Autumn colours that nature puts on each year if you live in the latitudes where deciduous trees flourish? A love that is, tempered by the knowledge of the meaning which this colourful transformation signals – the end of Summer and the advent of Winter – only young children are blissfully unaware of the message and thoughtlessly kick their way through the ever-deepening piles of fallen leaves.
The change begins on the edge of some leaves on a certain side of some trees and gradually creeps across the entire tree, to be joined at differing rates and with subtly different palettes by other species until whole stands of woodland are ablaze save for the odd patch of evergreens. But this extravagant show, which has us humans travelling to see its most spectacular examples, is not some random quirk of nature, but a necessary part of the plant’s process – one without which the trees would not survive the coming cold of Winter. The green, chlorophyll-filled engine of energy conversion which is a leaf, exchanging liquid food from the tree and using sunlight to power the tree, now switches its production to producing a kind of anti-freeze which the tree reabsorbs into its twigs, branches and trunk to protect itself against frost damage. Once each leaf has done its job, sucked dry by its parent, it shrivels and falls to the ground where it will rot down and feed the tree through its roots and complete the cycle of its life but the byproduct of its transformation in Autumn is a breathtaking, spectacular, partial rainbow from yellow to rich reds…
Autumn colours show
as leaves transform their sap to
save the tree from frost
