With its stout, upright stems and large leaves, this very vigorous perennial grass resembles large corn stalks. This species is the source of the reeds used in musical instruments. The semi-woody stems are also used for a variety of other purposes in its native region. This is also often the plant referred to when "reeds" are mentioned in the Bible. Forms large, dense clumps but spreads slowly (here, at least; but see note below). Leaves are 1-2' long, about 2" wide. Flower cluster to 2' long, very showy, but produced only in areas with a long growing season. Likes moisture; will grow well in or near water. Should be given a mulch for winter protection in zones 5 and 6, at least until well-established.
Note: In northern areas (such as our location), Arundo donax makes a striking specimen but is not inclined to become invasive. In warmer climates, and especially in the southwestern states, it can apparently be quite invasive. In such areas the plant should be used cautiously, if at all.
