Phalaris aquatica, known by the common names bulbous canary-grass[2] and Harding grass, is a species of grass in the genus Phalaris of the family Poaceae.

Description[]

It is an erect, waist-high, stout perennial bunch grass with grayish to bluish green leaves. Flowering heads are dense, spike-like, and usually two to five inches long. It is slow to develop from seed, but can form large bunches after several years.[3]

Phalaris arundinacea (reed canary grass) differs from Harding grass in having more distinct rhizomes and an inflorescence that is compact at first but later becomes more open as the branches spread.

Hybrids of harding grass and reed canary grass have been produced. Varieties include 'AQ1', 'Uneta', and 'Australis'.

Geography[]

Phalaris aquatica originated from Southern Europe and the Caucasus. It is now naturalized in South Africa, Australia, New Zealand and the USA.[4]

Chemical constituents[]

Leaves and seedlings contain dimethyltryptamine, 5-methoxy-N,N-dimethyltryptamine, bufotenin and related compounds,[5][6] and gramine.[7]

Forage[]

Phalaris aquatica is a pasture species grazed by ruminants. The grass can also be cut, providing good quality fodder for grazing livestock for 8 to 12 months a year.[4]

Toxicity[]

Some Phalaris species contain gramine, which can cause brain damage, other organ damage, central nervous system damage and death in sheep[7] although Phalaris aquatica is said to be non-toxic.[8]

Raw, dried Phalaris aquatica contains approximately 0.1% DMT, 0.022% 5-MeO-DMT, and 0.005% bufotenin.[6] A particular strain of P. aquatica from Italy, labeled 'AQ-1', was reported to contain in excess of 1.0% alkaloid concentration.[9]

Seeds

In Victoria, Australia, it is reported that kangaroos grazing on Phalaris aquatica may develop a condition known familiarly as 'Phalaris staggers', where coordination and mobility are affected.[10]

Invasive species[]

Harding grass is an invasive species in grassland, oak woodland, chaparral, and riparian habitats. Native grasses and grassland habitat in California are affected.
