It is native to Eurasia, in Eastern Europe and Western Asia. "Fagus orientalis" is a large tree, capable of reaching heights of up to tall and trunk diameter, though more typically tall and up to trunk diameter. The leaves are alternate, simple, and entire or with a slightly crenate margin, long and broad, with 7–13 veins on each side of the leaf (6–7 veins in "F. sylvatica").

The terminal bud emits a hormonal substance in the spring that halts the development of additional buds. This tendency, though very strong at the beginning of their existence, becomes weaker in older trees. It is only after the budding that root growth of the year begins. The first roots to appear are very thin (with a diameter of less than 0.5 mm). Later, after a wave of above
