Calamagrostis canadensis

Blue Joint grows as a large creeping grass in wet places or meadows from Manitoba to New Mexico, Newfoundland to California. In California Blue-joint lives from about Tulare Co. north in the Sierras, and Mendocino county north in the coast ranges. This range is largely limited by rainfall. If you water a little this grass will grow anywhere. (Syn. Arundo canadensis, C. michauxii, Arundo fissa, Deyeuxia, Calamagrostis langsdorfii var. acuminata, C. oregonensis, C. pallida, C. lactea, C. inexpansa cuprea)
