Description
 
 

Reed canary grass plant often appears in dense colonies that crowd out all other species. It often dominates wet areas.

The blades are flat, ¼ to ¾ wide, and up to 20 long.

The ligule is a thin, papery membrane from just over to just over long. The margin is irregularly jagged, as if torn.

The inflorescence is 2½ to 7 long, usually 3 to 6, and is borne high above the leaves. It is always evidently branched, at least near the base; the branches are short. When immature, it is compact and resembles a spike. When in full flower, it is open and green or slightly purple or reddish. Later, it turns tan to whitish in color and closes up, becoming narrow and pointed.

Similar Species

 
 

Orchard grass (Dactylis glomerata) has an inflorescence that is similar in appearance. However, the leaves are much narrower. The inflorescence is wider with a more blunt tip.

Bluejoint (Calamagrostis canadensis) has a ring of hairs just below the nodes.
