Additional recommended knowledge
Various species of Phalaris grow on every continent except Antarctica. Found in a broad range of habitats from below sea level to thousands of feet above sea level and from wet marshy areas to dry areas. P. arundinacea and P. aquatica are sometimes invasive species in wetlands.
Some research has been done into the variability of alkaloids in the Phalaris grasses. Strains with high levels of alkaloids are best avoided in locations with grazing cattle and sheep, due to potential toxicity. Such high-alkaloid strains include Phalaris Aquatica AQ-1 and the species Phalaris brachystachys. Seasonal and weather patterns also appear to affect alkaloid concentration, as most toxicity occurs in autumn and in times of drought. Regrowth after grazing or mowing also shows a considerable increase in alkaloids.
None of the above alkaloids are said to have been found in P. californica, P. canariensis, P. minor and hybrids of P. arundinacea together with P. aquatica.
Used in dried flower arrangements. Phalaris canariensis is commonly used for bird seed.
