Blue-joint Grass
Calamagrostis canadensis

a.k.a. Canada Bluejoint

Cool-season, perennial grass with a mature height of 2-4'. It has many very slender stems that arise from small rhizomes. Canada blue-joint is used in upper shoreline zones and in vegetated swales. This species also does well in landscaping, restorations (especially wetland, wet meadow and wet prairie), and mitigation sites. It provides good wildlife habitat for songbirds.

USDA symbol: CACA4
