Sue Whigham admires autumn displays of glorious colour

It’s the first week of September and a glorious morning
for a walk so it’s on with the boots, on with the
dog’s lead and off down the lane. There are plenty of
blackberries in the hedgerows and a pair of buzzards are
mewing overhead. A group of swallows is gathering in my
neighbour’s field and we come upon thirty or so rooks
feasting on the recently harvested fields. Then through the
stile and across the fields to the back of the church, gathering
a few field mushrooms on the way whilst keeping our eyes
peeled for the beginning of any change in leaf colour. Each
year is different depending on conditions as far back as the
spring, but this year, well, the cornus in the hedgerows has
already turned a deep purple which, combined with blackberries,
is pretty stunning. The hornbeams are losing their
leaves faster than they have time to turn which, bearing
in mind how dry it was this summer, is hardly surprising.
Patches of the tall limes we pass have become a glorious
yellow and the ash by the gate is just on the turn.
In the garden two tree species are beginning to put on a
show. On the strength of seeing an avenue of limes, Tilia
cordata ‘Winter Orange’ at RHS Wisley a few years ago,
we planted one here. This is a really lovely selection with
red buds and bright orange winter shoots. It hasn’t flowered
for us yet but we don’t want to be greedy as we now have a
lovely autumn display of buttery yellow leaves and they are
certainly enough to be going on with. The other tree that
really is worth its weight in gold is Crataegus x persimilis
‘Prunifolia’. I’m sure I’ve mentioned it umpteen times but it
is a tree which deserves more than just one passing comment.
What are its attributes? Well, it’s an all rounder really with
showy blossom in the spring, and rather shiny oval leaves
which by now have coloured up in varying shades of red and
orange. These are accompanied by large clusters of red fruits.
Leaves are green because of a pigment known as chlorophyll.
We’ll all remember that from our Biology lessons at school.
And so when a tree is healthy and happy this pigment
dominates any other in the leaf and is absolutely vital to
the tree. The energy stored by the chlorophyll from the sun
is combined with the water taken up by the plant’s roots
and carbon dioxide taken from the air to produce what the
tree needs to survive, i.e. food. So this is why trees are so
vital to us humans. They create oxygen by this process and
reduce the levels of carbon dioxide in the atmosphere which
we create and which is definitely not beneficial to us.
During the summer months, chlorophyll is
constantly breaking down and being replaced by
the tree and during the approach to autumn, and
then into winter, is withdrawn from its leaves.
This is a bit like closing down a valve to reduce the flow
of water in a plumbing system and is so clever. Where
