Phalaris arundinacea L.
Reed Canary Grass
Poaceae (Grass Family)
Synonym(s): Phalaris arundinacea var. picta, Phalaroides arundinacea, Phalaroides arundinacea var. picta
USDA Symbol: phar3
Grows in large patches, the flowering stalks jutting in a uniform layer over the leaves, which also grow to a uniform height. The flower stalks do not persist long after flowering.
This grass is much planted for hay but is also naturally established. Like many marsh plants, Reed Canary Grass spreads by rhizomes and soon forms large patches. The inflorescences can be mistaken for those of Orchard Grass (Dactylis glomerata), but they are more fragile and smooth-textured, and the growth habit is different: Orchard Grass grows in distinct clumps on drier soil. A cultivated variety of Reed Canary Grass, Phalaris arundinacea 'Picta' with white stripes on the leaves, is known as Ribbon Grass and is often planted in gardens.
