Eastern Hemlock (Tsuga canadensis) grows throughout New England and provides food, medicine, shelter, and much more for a host of insects, birds, and mammals. Identification features include: ~1/2" long, flat needles with white stripes below and short, bent stalks; ~3/4" long, dangling seed cones; and bumpy twigs (easily observed on dead branches). My favorite field mark requires a close look: miniature (often upside-down) needles line the tops of branches (see top photo).
The needles of Eastern Hemlock can be used to make a fragrant tea in much the same way as Balsam Fir needles. To avoid too strong a tea, I recommend starting with a couple of finger-length branchlets. Remember to bruise the needles (by rubbing or chopping) prior to covering with hot water to help release their inner constituents.
