Phragmites communis is a highly invasive herbaceous grass. A large perennial grass native to wetland sites throughout temperate and tropical regions of the world.
This reed tends to produce extensive stands, sometimes over a square kilometer which are known as reed beds. The horizontal ‘runner’ stems can move this plant over 5 miles in a year. Shoots and rhizomes grow from the nodes, spreading the plant far beyond its original bounds. Phragmites can grow to 20 feet tall with stems of fluffy grey to tan seed heads.
