Common name: Western hemlock
Tsuga heterophylla is native to the Pacific coast from Northern California to Southern Alaska. It is a very large tree and is recognizable by its drooping tip. Western hemlocks are the most shade-tolerant and have the densest canopy of any tree on the Pacific coast, which is why you see their seedlings thriving in dark, shady forest understories.
