Dawyck purple beech is a narrow and upright branching columnar tree with dark purple leaves. Attractive if planted as a tall hedgerow. Serrated leaves emerge and remain dark purple until transforming to a spectacular copper foliage in autumn. Smooth barked, upright silvery-grey branches provides a striking winter interest. Very densely branched and tall, up to 50 ft. and 10 ft. wide, requires almost no pruning to maintain its form. Zone 4-9.
