Arundo donax GIANT REED This amazingly tall bamboo-like plant has blue-green corn-like foliage that grows 2 - 3 in. wide and 18-24 in. long. Arching upright canes form large clumps that create a dramatic effect. Useful as a specimen, screen or a windbreak, or when planted with a wall or building as a backdrop. Prefers fertile, moist, well drained soil, but is not picky. Tolerates heat and seaside conditions. Very vigorous, it can colonize quickly, especially in moist areas. Rarely invasive in norhtern climates.
