Arundo donax (Poaceae)

Giant reed is one of the largest grasses, reaching 12-16 feet in height, and looks similar to sugar cane. It was introduced to Hawaii as an ornamental and is native to the Mediterranean. In Hawaii, giant reed is spread vegetatively when soil containing parts of the roots is moved. Across the southern United States, giant reed has spread primarily through waterways and it can be found along roadsides, in ditches and waterways.

In Southern California, resource managers have dubbed Arundo donax the "weed from hell". One example of the problems caused by giant reed was the collapse of a bridge to Camp Pendleton, attributed to massive amounts of giant reed damming the Santa Margarita River during heavy floods. This prompted the military to control the plant for base security reasons. Currently, most populations on Maui are found in yards and open lots. MISC currently limits control efforts to locations that are near wetlands and high value natural areas.
