Giant reed grass: Arundo donax
An extremely large, rhizomatous perennial, giant reed grass has a coarse texture similar to that of bamboo or corn and wide, straplike foliage that arches away from its canelike stems. After reaching a mature height of 10?15 feet in fall, plumes of pale-green and purple flowers emerge and persist into winter. A variegated cultivar, 'Variegata Superba', with white stripes and margins is widely available. Giant reed grass can be invasive and requires regular maintainance. Profile
