Reed canarygrass (Phalaris arundinacea)

This tall reed-like perennial grass grows and spreads from stout rhizomes. Stems are hollow and can be 2 to 6 feet tall. This grass looks similar to our native bluejoint grass but prefers moist sites and is an invader of wetlands in other states. Once established, it is difficult to remove and has the ability to dominate riparian areas and change spawning habitat. This grass stays green later than our native grasses and will exclude other vegetation over time.

Please do not plant Reed Canarygrass and control it's spread here on the Kenai.
