Phalaris arundinacea (weed) L. - (reed canarygrass)

This grass is native to North America, Europe and Asia and can form dense monospecific stands through its rhizomes, especially in wetland areas. It establishes and spreads rapidly. It has become an aggressive invader in North America, and populations are genetic mixtures of European cultivars, planted as forage crops, and native populations.

P. arundinacea is a perennial grass that grows up to a height of 2 m, with panicles up to 30 cm long. The flowers are wind-pollinated and self-incompatible. The seeds float on water and can spread long distances.
