Air Jordan

A tall, erect, perennial cane- or reed-like grass, which looks very similar to bamboo, and grows in thick clumps that tower from 2 to 8 meters high. Roots are strong and fibrous. Grey to yellowish-green stems are hollow and jointed, resembling cornstalks. The blue-green leaves are about 1 inch wide and 12 inches long. Its most recognizable feature is its large, dense, purple flower or seed plume, which grows up to 3 feet long and blooms in the fall.
