Coefficient of Wetness:
Typically with beech, sugar maple, yellow birch, and often white pine, but also in coniferous swamps and on forested dunes; often in groves on knolls or in ravines.
The short needles, mostly 6–13 (–16) mm long, in flat sprays, and the small female cones, mostly 13–22 mm long, are characteristic of this species. The needles of hemlock are minutely toothed toward the rounded apex and are on distinct, raised pegs ca. 0.5 mm long. The hemlock woolly adelgid (Adelges tsugae) has recently been discovered in Michigan and poses a serious threat.
Lenawee Co. records are spread from cultivated trees, as perhaps also a few other collections from southeastern Michigan
