Wire grass is a type of tough, wiry and persistent grass that is commonly found in the South Eastern United States. This grass is also known by various other names such as Bermuda grass, couch grass, devil's grass, and dog's tooth grass. Its scientific name is Cynodon dactylon. Wire grass is often considered a weed because of its invasive nature and difficulty to eradicate. It grows quickly in dry and hot conditions, and its roots are deep, making it hard to remove. This grass is also used for pasture and turf in some regions. Despite its various names, wire grass always evokes a sense of toughness and resilience.
