Phalaris arundinacea, or reed canary grass, is a tall, perennial grass that commonly forms extensive single-species stands along the margins of lakes and streams and in wet open areas, with a wide distribution in Europe, Asia, northern Africa and North America. Other common names for the plant include gardener's-garters and ribbon grass in English, in French, in German, in Japanese, in Portuguese, and and in Spanish.Phalaris arundinacea. USDA NRCS Plant Guide.
Description The stems can reach in height. The leaf blades are usually green, but may be variegated. The panicles are up to long. The spikelets are light green, often streaked with darker green or purple.Phalaris arundinacea. Flora of China. This is a perennial grass which spreads underground by its thick rhizomes.
Uses A number of cultivars of P. arundinacea have been selected for use as ornamental plants, including variegated (striped) cultivars – sometimes called ribbon grass – such as 'Castor' and 'Feesey'. The latter has a pink tinge to the leaves.Phalaris arundinacea var. picta 'Feesey'. When grown, although drought-tolerant, it likes abundant water and can even be grown as an aquatic plant.
Reed canary grass grows well on poor soil and contaminated industrial sites. Researchers at Teesside University's Contaminated Land & Water Centre have suggested it is ideal for phytoremediation, which improves soil quality and biodiversity at brownfield sites.
The grass can also easily be turned into bricks or pellets for burning in biomass power stations. Furthermore, it provides fibers which find use in pulp and papermaking processes.Andersson, B. and E. Lindvall. Use of biomass from reed canary grass (Phalaris arundinacea) as raw material for production of paper pulp and fuel. internationalgrasslands.org.
P. arundinacea is also planted as a hay crop or for forage.
This species of Phalaris may also be used as a source of the psychedelic drugs DMT, 5-MeO-DMT and 5-OH-DMT (bufotenin), as well as Hordenine and 5-MeO-NMT; however, N,N-DMT is considered most desirable. Although the concentrations of these compounds are lower than in other potential sources, such as Psychotria viridis and Mimosa tenuiflora, large enough quantities of the grass can be refined to make an ad hoc ayahuasca brew.
Ecology In many places, P. arundinacea is an invasive species in wetlands, particularly in disturbed areas. It has been reported as an invasive weed in floodplains, riverside meadows, and other wetland habitats around the world. When P. arundinacea invades a wetland, it inhibits native vegetation and reduces biological diversity.Kim, K. D., et al. (2006). Controlling Phalaris arundinacea (reed canarygrass) with live willow stakes: A density-dependent response. Ecological Engineering 26 pp. 219–227. . It alters the entire ecosystem.Lavergne, S. and J. Molofsky. (2004). Reed canary grass (Phalaris arundinacea) as a biological model in the study of plant invasions. Critical Reviews in Plant Sciences 23(5) 415–429. . The grass propagates by seed and rhizome, and once established, is difficult to eradicate.
Distribution P. arundinacea now has a worldwide distribution. While it is generally considered to be native to both North America and Eurasia, this is a matter of debate. It appears that the North American populations are a mixture of introduced European cultivars and indigenous varieties. citing, inter alia,
Chemical properties Specimens contain varying levels of hordenine and gramine.
Leaves of P. arundinacea contain DMT, 5-MeO-DMT and related compounds. citing Levels of beta-carbolines and hordenine have also been reported.
