Beech (Fagus) is a genus of ten species of deciduous trees in the family Fagaceae, native to temperate Europe and North America.
The leaves of beech trees are entire or sparsely toothed, from 5-15 cm long and 4-10 cm broad. The flowers are small single-sex, wind-pollinated catkins, produced in spring shortly after the new leaves appear. The bark is smooth and light gray. The fruit is a small, sharply 3-angled nut 10-15 mm long, borne in pairs in soft-spined husks 1.5-2.5 cm long, known as cupules. The nuts are edible, though bitter with a high tannin content, and are called beechmast.
Beech grows on a wide range of soil types, acid or basic, provided they are not waterlogged. The tree canopy casts dense shade, and carpets the ground with dense leaf litter, and the ground flora beneath may be sparse.
Beech was a late entrant to Great Britain after the last glaciation, and may have been restricted to basic soils in the south of England[1]. Today, beech is widely planted for hedging and in deciduous woodlands, and mature, regenerating stands occur throughout mainland Britain below about 650m[2].
The southern beeches Nothofagus previously thought closely related to beeches, are now treated as members of a separate family, Nothofagaceae. They are found in Australia, New Zealand, New Guinea, New Caledonia and South America.
The beech blight aphid (Grylloprociphilus imbricator) is a common pest of beech trees. Beeches are also used as food plants by some species of Lepidoptera (see list of Lepidoptera that feed on beeches).
The beech most commonly grown as an ornamental tree is the European Beech (Fagus sylvatica), widely cultivated in North America as well as its native Europe. Many varieties are in cultivation, notably the weeping beech F. sylvatica ‘Pendula’, several varieties of Copper or purple beech, the fern-leaved beech F. sylvatica ‘Asplenifolia’, and the tricolour beech F. sylvatica ‘roseomarginata’. The strikingly columnar Dawyck beech occurs in green, gold and purple forms, named after Dawyck Garden in the Scottish Borders, one of the four garden sites of the Royal Botanic Garden Edinburgh.
