About

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

Safety

Grazing on Phalaris-dominated pastures can cause livestock toxicoses:

Phalaris staggers: A chronic neurological condition associated with ruminants grazing Phalaris containing toxic alkaloids; appropriate cobalt supplementation can reduce the risk of the staggers syndrome.
