The most widely distributed species in the genus Arundo, and a member of the Grass family. Arundo donax is best known for its use in the production of reeds for wind instruments. It is one of the largest grasses, with stalks growing sometimes to eight meters high. The stalks are hollow, with partitions at the nodes. The internodes are between 10 and 30 cm long, so another handy use of this plant is in the making of cane flutes.

Arundo donax grows in moist areas all over the world. Because it's so widely distributed, it has many common names, including donax cane, giant reed, bamboo reed, Italian reed, Spanish reed, Danubian reed, or Provence cane, in English-speaking countries. It's not the same as the oriental bamboo.

This plant is cultivated in southern France for use in the making of reeds for clarinet, saxophone, and for the double reeds. It has also been cultivated in other areas as a source of cellulose for rayon and for making paper.
