Arundo donax is classified as a tall perennial cane plant or reed. It is a member of the Poaceae (grass and bamboo) family.It is called by several common names such as Giant reed, Elephant grass, Carrizo, Arundo, and Giant cane.It grows best in a wetland environment, and has been successfully planted all over the world.Unfortunately, it has been somewhat too successful in some places as it has an invasive root system. These roots can prevent other plant life from growing in the same area because of how tightly bound the root fibers are as they spread.
