Cogongrass, Imperata cylindrica(L.) Beauv.,is an aggressive weed that is found throughout Northwest Florida. This weed is considered to be one of the world’s worst weeds, and is listed as a Federal Noxious Weed by USDA-APHIS-PPQ. Cogongrass is a nonnative, aggressive, colony-forming perennial grass. Leaf blades are narrow and erect; tips are sharp and pointed, have short fine hairs at the base, are flat and smooth above with a whitish midvein noticeably off-center, and the blade margins have very small needle-like foldable projections. The flowers are white, silky, and plume-like.
Cogongrass harms your land by invading a wide variety of habitats, including forests, pastures, roadsides and ditches. It spreads rapidly, forming thick mats, excluding all other vegetation, and reducing wildlife habitat. Cogongrass is extremely flammable, creating hazardous wildfire and prescribed-burn conditions.
