Eastern Hemlock is a medium sized evergreen tree with slightly dropping crown leader. It generally grows 60-70' in height, and 1.5-3' in diameter, though many older specimens reach heights of 100'-150' with a diameter of 5'. The oldest recorded specimen was 554 years old, and tallest recorded specimen 173'. It inhabits the Appalachian mountains from northern Georgia north into Maine, and west into Canada surrounding the Great Lakes area. It can be found on moist slopes, in rocky areas, as well as narrow stream valleys, at elevations 0-5,900ft. Its needles are 1/4"-1/2" long, dark green in color above, and white lined beneath. They form flat in cross section, arranged in two rows. Its cones are 1/2"-3/4" long, brown, ovoid, with round scales, hanging from the end of twigs. The invasive Asian insect pest, the hemlock woolly adelgid, infest these trees, killing them off in just a few years, threatening its population.
