Reed canary grass has invasive traits that enable it to spread aggressively. Reed canary grass is an unusual species that is thought to be native to North America, Europe, and Asia, with different ecotypes existing on different continents. These ecotypes look identical but vary in their growth. Reed canary grass is considered invasive in many areas and it is thought that the more aggressive Eurasian ecotypes have outgrown and possibly replaced, or hybridized with the native ecotypes. Review of risks should be undertaken before selecting this plant. The various cultivars of this species are more commonly available than the species itself.
