Calamagrostis canadensisAlso known as:
Calamagrostis canadensis is a clump forming, long lived perennial grass. It produces thin, erect stems that can grow to 5' tall. They have distinctive, prominent joints and a blueish color, which combine to create the common name: bluejoint. The leaves are slender and delicate. The flower heads are tight at first, then open to form drooping plumes as the seeds mature.
Bluejoint is a cold climate grass, adapted to a variety of moist environments including open woods, swamps, marshes, bogs, fresh water margins and wet prairies. It withstands seasonal to regular inundation up to 6". Clumps will spread slowly by rhizomes. It prefers rich, acidic soil in full sun. Calamagrostis canadensis is sod forming and very effective at stabilizing disturbed soil. This is a boreal species that can be found growing well within the Arctic Circle. Extremely hardy: zones 2-6
Best propagated from seed. Cant be propagated by clump or rhizome division.
Once a dominant prairie species, it is a favored grazing grass for large herbivores including bison and elk as well as domesticated cattle. It is also a source for food and shelter for a variety of birds, waterfowl, and small mammals.
