Blue Joint Grass Description

Blue Joint Grass, Calamagrostis Canadensis, Is A Perennial Grass Known For Its Longevity And Its Uses As Erosion Control And A Shoreline Stabilizer

Blue joint Grass, formally known as the Calamagrostis Canadensis, is a long-lived perennial grass that thrives in cool seasons. People often compare them to the similarly-built canary Grass. However, the latter is coarser and with reddish rhizomes near the soil surface. This Grass occurs from low to mid-elevation across most of Canada and the United States, save for the southeast. It grows in various environments, including meadows, open words, wet thickets or swamps, marshes, and margins of streams and lakes. It is an excellent addition to disturbed areas, easily colonizing forests following logging or fire.

As a mid-sized to tall native Grass useful for wetland restoration and water bank stabilization, this Grass provides forage for bison, elk, deer, food, and habitat for small mammals, waterfowl, birds, and birds bears. It also shows up in hydroseeding mixtures for drainage ditches that filter stormwater. Its creeping rhizomes improve the plant's ability to bind the soil, especially along higher-gradient streams and waterways. With its height ranging from sixty to eighty centimeters tall, there are three to eight nodes along its stems, and this Grass spreads slowly, forming a sod.

Its foliage is ribbed, lax, rough to the touch, and three to eight millimeters wide. The panicle is relatively narrow open and loosely branched, flowering in late June or July before the seed matures in August. The blue joint seeds are tiny, have fine hairs attached to the hull, and are easily windborne. Though it is common in many areas of the northern boreal and temperate forests, it is scarce to nonexistent in the Willamette Valley of Oregon. However, it is more abundant along the Pacific Coast near lakes and the Puget lowlands of Washington. The seed ripens in late summer, and its quality reaches its peak in the spring before maturity.

Blue Joint Grass, Calamagrostis Canadensis Seed Is Best Grown In Moist Soil Conditions, Where It Is Less Prone To Overgrazing

Since the blue joint seed has no dormancy, it only germinates when sown during the fall or spring. Its basal hairs should receive a debearding to improve seed flow, but because the blue-joint Grass is sensitive to overgrazing in some regions, moist soil conditions help restrict spring grazing. In this case, one must time livestock utilization according to how dry the soils are and the stage of plant maturity. This Grass remains viable for up to five or seven years, and it furnishes substantial amounts of herbage, with its stands hayed in the Midwestern states. Blue joint seeds and nursery stocks are more readily available in the West, Midwest, and Northeast United States. Blue joint Grass - Calamagrostis Canadensis - its name Blue joint alludes to the blue-purple hue of the nodes within the cluster.

Known for its long lifespan and exceptional hardiness, this Grass is a cool-season perennial grass belonging to the Poaceae family. It is the most abundant and ubiquitous Calamagrostis species throughout North America. 

It is a summer-flowering plant that grows from short rhizomes and has a vast, arching inflorescence. It grows in clumps and is distinguished by its many thin, tall blue-green stems ornamented with noticeable joints. It is an essential component of wet prairies and sedge meadow regeneration. A nice sod may be developed on damp grounds due to this plant's shallow roots and quick proliferation.

The floral plumes are initially purplish in hue but become tan in color. However, its beauty still doesn't diminish since it is a perennial grass that is appealing all year round, owing to its blue-green shade in the summertime or blonde hue in the winter. It blooms from late spring to early summer and produces lovely pink-green seeds.

This perennial Grass grows in thick stands or tufts of culms that range in height from 2 to 5 feet. Typically, the flowering time for a colony of these plants comes around early to mid-summer and lasts about 1-2 weeks. Traditionally, this plant has long been used as a significant source of nutrition for bison. Furthermore, it serves as food and habitat for a diverse range of birds and smaller animals.

Having full or partial sun exposure, wet to moist soil circumstances, and mild to warm summertime temperatures are the preferred conditions to grow this plant. Loam, clay, silt, sand, or a mix of the soil mentioned above are all suitable habitats for this kind of Grass. It also has a wide pH range of tolerance.

This Grass will endure as long as the stagnant water does not remain during the growth period. The ability to withstand the winter is exceptional with this plant. This Grass has the potential to expand vigorously in certain areas. Because the young seedlings are so sensitive, it is easier to establish the plant via the division of its rhizomes rather than by seed.

This Grass is most commonly associated with sedges, making it desirable for wetlands restoration. It develops into a thick patch of Grass with many fibrous roots, making it an excellent choice for streambank reinforcement or coastline restoration projects, among other things. In certain areas, the Grass is challenging to locate in bloom since the flowers fade quickly and are replaced by pale-brown panicles of maturing seeds, which are difficult to distinguish from the rest of the Grass. On rare occasions, the panicle as a whole fails to develop, and the spikelets stay barren and fade in appearance.
