What is the best way to go about getting rid of it and starting a plot? Hybrids of Harding grass and reed canary grass have been produced. Reed canarygrass has unjustly gained a reputation as a low quality, undesirable forage. Knowing the superb diversity of native, non-cultivar species which is present before reed canary takes hold, it's discouraging to see that diversity disappear. Dominated by bluejoint (Calamagrostis canadensis var. The leaf margins are rough and the sheaths are overlapping. Reed Canary Grass . Ensure positive identification before attempting control. Seeing reed canary grass occupying stream and lake edges, wetlands, even damp parts of otherwise dry prairies, and continuing to expand into healthy, wildlife-rich habitat, is a heartbreak. Flowers are densely clustered in panicles with 3 florets per spikelet, one floret is fertile while the other two are sterile. The roots and old plant material form a thick mat which prevents other plants from becoming established. Reed canary grass is a tall, fast growing grass that commonly invades wetlands. Numerous studies have demonstrated that it has strong negative impacts on native wetland species and wetland restoration requires that it be controlled. Reed Canary Grass. In the UK reed canary grass is generally used to provide cover for farmland birds or game cover. Varieties include 'AQ1', 'Uneta', and 'Australis'. Its leaves are hairless, reaching up to 10” long and 1⁄4″ to 1⁄3″ wide. Fire can help control the spread of reed canary grass and keep it out of high quality wetlands. Description. Phalaris arundinacea (reed canary grass) differs from Harding grass in having more distinct rhizomes and an inflorescence that is compact at first but later becomes more open as the branches spread. Reed Canary-grass - Phalaris arundinacea. It is particularly well adapted to wet soils and soils with a pH below 6.0. Aug 4, 2016 #2 Drown it or farm it, with combo of herbicide. Flowers are green to purple, but fade to beige as seeds ripen. Only the ribbon grass cultivar (P. arundinacea var. Leaf blades are flat, 1-4 feet long, up to 0.75 inches wide, glabrous and taper gradually. The good news is that we can identify it from a distance, and when looking closer see a distinctive diagnostic trait: it has a papery ligule (where the leaf attaches to stalk) that stands up 3 mm or ~ ¼”. The stem is hairless and stands erect. Old varieties were high in alkaloids, which over time can cause animals to decrease consumption. DISTRIBUTION AND HABITAT: Reed canary grass is a cool-season, sod-forming, perennial wetland grass native to temperate regions of Europe, Asia, and North America. This species of Phalaris was found to have the richest overall alkaloid content in the investigation of Phalaris species conducted by Festi and Samorini. Its stem and leaves are bluish-green in color with tapering leaf blades, and has dense clustered flowers that bloom May-mid June. Reed canary grass (hereafter RCG) is a threat to the ecological integrity of countless wetlands across Wisconsin. Reed Canary Grass, Phalaris arundinacea, photo by Wasowski, Sally and Andy. Reed grass is found throughout all but the coldest areas of the world and is primarily used by farmers and governments for erosion control purposes. The Eurasian ecotype has been selected for its vigor and has been planted throughout the U.S. since the 1800's for forage and erosion control. In the UK it is used to provide cover for wildlife and game birds. Bernthal and Hatch (2008) found that 1 in 7 wetland acres in their southern and south-central Wisconsin study area were heavily dominated or co-dominated by RCG, and approximately 500,000 acres of wetlands in the entire state are infested.
