Tsuga canadensis

Canadian Hemlock
Pinaceae
Evergreen, Trees

TSUGA

These are mostly big, shallow-rooted trees with unusually graceful appearance. Horizontal to drooping branches bear needlelike leaves that are banded with white beneath, flattened and narrowed at the base to form distinct, short stalks. Small, oval brown cones hang down from branches. Deeply furrowed bark. Need some winter chill. Do best with acid soil, summer humidity, protection from hot sun and wind. Take well to heavy pruning; make excellent clipped hedges, screens. Easily damaged by salt and drought. In the Northwest, the hemlock woolly aphid can weaken these plants, especially those grown as hedges; it affects mainly T. heterophylla.
