European hornbeam

European hornbeams are excellent in groupings around large buildings and also useful as screens, hedges and windbreak trees. The European hornbeam has densely textured foliage, and handsome, slate gray smooth to fluted bark. The dark green leaves turn an attractive yellow in the fall, and the bark and buds are ornamental in winter.
