This tree was young when Culloden was fought

Aigas Field Centre, Beauly, Highlands I am struck by the way the willow expresses the richness entailed in a drawn-out death

Just 10 minutes down the valley from this outstanding educational institute is the largest goat willow in Britain. The veteran is tucked away at the roadside amid a line of alders and so sunk in a deep and almost subaquatic gloom that you could easily miss it. A visit also requires a minor girding of loins to brave the midge-laden atmosphere, although meeting the tree on intimate terms is worth any amount of insect nuisance.
