The word ‘tree’ covers such a variety of form, colour and texture in bark, branches and leaves. The deeply ridged trunk of a grand old chestnut tree contrasts with the graceful branching pattern of its neighbour.
The warm brown, peeling bark of a rhododendron matches the shade of the fine, downy hairs covering the underside of its big, leathery leaves.
And the new leaves of a golden sycamore glow in a tangled tracery of twigs.
