Weeping beech measure in length. Flowers appear in the spring and are inconspicuous. The beechnuts sit in a thin spiny husk and are less than 5 cm in diameter. The triangular beech nuts are popular in autumn with birds, mice and squirrels. The green leaves become copper-toned in the fall. In winter the skeleton of the silvery stem with its branches remains attractive. The purple pigment in the leaves acts like a sunscreen to protect its new leaves, which is particularly important for plants that grow at high altitudes where the sun is fierce. The tree is not native to North America
English Lowlands beech forests include the Devil's bolete and hedgehog mushroom. At the end of the last glaciation, about 10,000 years ago, the area's ecosystem was characterised by a largely treeless tundra. Pollen studies have shown that this was replaced by a taiga of birch, and then pine, before their replacement in turn (c. 4500 BC) by most of the species of tree encountered today - including, by 4000 BC, the beech, which seems to have been introduced from mainland Europe. This was used as a source of flour, ground from the triangular nutlets contained in the "mast", or fruit of the beech, after
