West Coast Hemlock is a tree species that grows in the Pacific Northwest region of North America. It is also commonly referred to as Pacific Hemlock or Western Hemlock. The word "hemlock" is often used to describe coniferous trees of the genus Tsuga in the family Pinaceae and is sometimes confused with the poisonous plant known as Hemlock. However, West Coast Hemlock does not pose any risk to human health and is highly valued for its wood and ornamental uses. Other synonyms for West Coast Hemlock include Mountain Hemlock, Alaska Hemlock, and Sitka Hemlock, which refer to different subspecies or variations of the tree found across the region.
