A variegated form of Phalaris arundinacea in the garden of Islington College, Nepal

Phalaris arundinacea, sometimes known as reed canary grass, is a tall, perennial bunchgrass 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.[1] Other common names for the plant include gardener's-garters in English, alpiste roseau in French, rohrglanzgras in German, kusa-yoshi in Japanese, caniço-malhado in Portuguese, and hierba cinta and pasto cinto in Spanish.[2]

Description

The stems can reach 2 meters in height.[3] The leaf blades are usually green, but may be variegated. The panicles are up to 30 centimeters long.[3] The spikelets are light green, often streaked with darker green or purple.[4] This is a perennial grass which spreads underground by its thick rhizomes.[3]

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.[5] When grown, although drought-tolerant, it likes abundant water and can even be grown as an aquatic plant.[5]

Reed canarygrass grows well on poor soils and contaminated industrial sites, and researchers at Teesside University's Contaminated Land & Water Centre have suggested it as the ideal candidate for phytoremediation in improving soil quality and biodiversity at brownfield sites.

The grass can also easily be turned into bricks or pellets for burning in biomass power stations.[6] Furthermore, it provides fibers which find use in pulp and papermaking processes.[7]

P. arundinacea is also planted as a hay crop or for forage.

This species of Phalaris may also be used as a source for the psychedelic drugs DMT, 5-MeO-DMT and 5-OH-DMT (bufotenin), as well as Hordenine and 5-MeO-NMT;[8] however, N,N-DMT is considered most desirable. Although the concentrations of these compounds is 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 habitat types around the world. When P. arundinacea invades a wetland, it inhibits native vegetation and reduces biological diversity.[9] It alters the entire ecosystem.[10] The grass propagates by seed and rhizome, and once established, is difficult to eradicate.[11]

Chemical properties

Some species contain gramine.

Leaves of P. arundinacea contain DMT, 5-MeO-DMT and bufotenin.[12] Levels of beta-carbolines[13] and hordenine[14] have also been reported.
