Previous | Prairie Home | Next

Bluejoint is a perennial grass with many narrow leaves each of which is about a foot long, often forming large patches that may exclude other species of grasses and forbs. Seedheads are tall and narrow, but may range from dense to loose. Stems may grow from 1-5 feet in height. Typically, bluejoint grass is found in wet meadows, wetlands, and along lakeshores.

Bluejoint grass is one of the most common native reed grasses and is found across much of North America.

Waterfowl will feed on the seeds, as do muskrats and deer. In times past, it was an important forage crop for bison.
