Quick Overview:

Tsuga canadensis, commonly called Canadian hemlock or eastern hemlock, is a dense, pyramidal conifer of the pine family that is native to moist woods, moist slopes, rocky hillsides/ridges, wooded ravines, and stream valleys from eastern Canada south to Maine and Wisconsin and further south in the Appalachian Mountains to Georgia and Alabama. It grows to 40-75’ tall in the wild. This species is noted for having the smallest needles and cones in the genus. Flat sprays of lacy evergreen foliage give this tree a graceful form. Lower branches often dip toward the ground. Thick and ridged bark on mature trees is red-brown to gray-brown. State tree of Pennsylvania. No part of this tree is poisonous. The poisonous hemlocks (Circuta maculata and Conium maculatum) are herbaceous perennials in the parsley family.  (Courtesy of Missouri Botanical Gardens Plant Finder)

Easily grown in average, medium moisture, well-drained soils in part shade to full shade. Best sited in part shade in sheltered locations protected from strong drying winds and hot afternoon sun. Tolerates full sun in cool northern climates, but dislikes the hot and humid summers of the deep South (particularly south of USDA Zone 6) where sun scald may damage the foliage when temperatures consistently exceed 95 degrees F. Intolerant of drought and should be watered regularly in prolonged dry spells, particularly when plants are young. Appreciates a thick winter mulch  (Courtesy of Missouri Botanical Gardens Plant Finder)
