Common Name: 
Hemlock

Some 9-10 species of evergreen trees of medium size to very large, pyramidal, with horizontal to drooping branches, relatively delicate and graceful.  Needles are short, blunt, flexible, spirally arranged.  The trees withstand full shade, but perform best in partial shade on acid soils with adequate moisture and good drainage.  They grow poorly under hot, dry summer conditions.  Native to North America (east and west coast), Himalaya, China, and Japan.   (This genus is NOT the poisonous hemlock, which are species of Cicuta and Conium of the Parsley family).
