IdentificationGiant Reed should be familiar to most people owing to its remarkable height, and it lives up to its name -- growing up to 15 or even 30 feet tall! Erect stems grow from thick, tough, horizontal rhizomes. The leaves are 2-ranked (distichous), up to a 3 feet long, and numerous. The inflorescence, when well-developed, is even larger than that of Phragmites and held prominently at the tip of the stem; however, it is seldom seen.
