Carex comosa Growing and Maintenance Tips

Native habitat includes swamps, boggy areas, wet ditches, and pond margins making it perfect for your constructed wetlands and restoration projects. As wetland preservation and restoration in the MidAtlantic becomes increasingly more important, this Carex has become instrumental in soil conservation on the edges of these installations. Excellent in bioswales as well. because it holds tightly when water makes a turn or changes direction even abruptly. C. comans has 'grabby" roots even in more silty soils. Definitely one to consider for these very properties but, it also has an attractive seed head which provides food for the Sedge Wren.
