Selected images for reed canarygrass (Phalaris arundinacea )
Reed canarygrass is a cool-season perennial grass that grows to 6 ft. (1.7 m) tall. Leaf blades are flat, 1-4 ft. (0.3-1.2 m) long, up to 3/4 in. (1.9 cm) wide, glabrous and taper gradually. The ligule is membranous (transparent) and long. The spreading flower/seed heads arise from hairless stems and can be green, purple, or brown in color and usually 3-6 in. (7.6-15.2 cm) in length. Flowering occurs from May to July. Reed canarygrass is variable in morphology, so characteristics may depend upon the habitat. It spreads by seeds and rhizomes and can quickly dominate wetlands, ditches, prairie potholes and other sites with moist soil. Reed canarygrass can exclude all other vegetation and is extremely difficult to eradicate once established. Debate exists as to the nativity of reed canarygrass; it is native to Europe and possibly parts of Asia, but it may also be native to the northwestern United States. Aggressive behavior that is exhibited in many parts of the central and western United States may be a result of escaped cultivars that were bred for vigor and quick growth.
