American dunegrass is hard to miss because it grows to a height of 6 feet and forms clumps along coastal dunes and also on sand and gravel beaches.  The blades are ¼- ½ inch (6-15 mm) wide and have a gray tinge.  Native to the West Coast of the U.S. and Canada, the species is also found on the American Atlantic Coast, around the Great Lakes, and in Asia.  This species is a member of the grass family.  It has also been known under the scientific name Elymus mollis.  Other common names for it include dune wildrye and sea lyme grass.
