Meadow Muses - January 2006
Winter Patterns – Bark, Twigs and Stems
As the trees and shrubs become bare we can begin to see things that have been hidden for much of the year and an array of differently coloured and textured bark patterns has emerged along the hedgerows and in the copses. The bark of a tree has various functions, including protecting the
tree from extremes of weather or from attack by fungi, bacteria and
grazing animals. Bark has two main parts, an inner layer of living
tissue and an outer, dead layer. On trees with thin bark the outer
layers sometimes peel or flake away but on those with thicker, persistent
bark the surface often develops deep fissures as the tree matures.
Browsing by animals such as deer and rabbits is a serious problem
and can kill a tree completely if the bark is grazed off in a circle
around the whole trunk. Some trees, such as Birch, have developed
a defence mechanism against this by producing thicker bark at the
base of the trunk, with much thinner bark higher up the tree where
browsing animals cannot reach.
This thicker bark can be seen at the base of mature Silver Birch trees, which have beautiful and varied bark patterns. The Birch trees in the meadow are still very young and have smooth bark with few fissures. The two photographs shown here were taken in another part of the park.
Many different bark colours and patterns can be found in our meadow, some of which are shown below.
Most of these photographs are of immature trees and hedgerow shrubs. It is quite difficult to reach the mature trees around the edge of the meadow because of a thick layer of brambles, thorns and climbers surrounding the hedgerows.
Once they have been laid bare by winter, the various twisted shapes
and colours of the hedgerow plants add the finishing touches to the
tapestry of winter bark in the meadow.
Featured Plant– Old Man’s Beard (Clematis vitalba)
Alternative names include Traveller’s Joy, Father Christmas, Baccy Plant, Boy’s Bacca, Smokewood, Shepherd’s Delight and Woodbine. The name Clematis is from the Greek meaning “long, lithe branches” and vitalba means “white vine”. The dry stems were traditionally cut in winter and used for smoking, giving rise to the names referring to tobacco, and Richard Mabey suggests in “Flora Britannica” that the plant may have inspired the Woodbine cigarette brand name. “Smokewood” may also refer to the appearance of the clouds of feathery fronds in the hedgerows when seen from a distance. The stems have also been used traditionally in basketry. In medicine the plant has been used in homeopathy to treat rheumatism, skin rashes and swollen glands. The boiled roots and stems were used traditionally as a cure for itching. The plant appears in the Bach Flower remedies, quoted for “Indifference, Dreaminess, Inattention and Unconsciousness”, and is one of the ingredients of the well-known Rescue Remedy.
