Agrostis canina, known as brown bent or velvet bent,[2] is a species of grass.

Description[edit]

Inflorescence

Agrostis canina is a perennial plant, with stolons but no rhizomes, and culms which grow to a height of up to 75 centimetres (30 in).[3] It is frequently confused with Agrostis vinealis (formerly treated as a subspecies or variety of A. canina), which grows in more upland habitats and has rhizomes rather than stolons.[2]

The leaf blades are 2–15 cm (0.8–5.9 in) long and 1–3 mm (0.04–0.12 in) wide,[4] with an acute or acuminate ligule up to 4 mm (0.16 in) long.[3]

The plant flowers from May to July,[2] and the inflorescence is a panicle 3–16 cm (1.2–6.3 in) long and up to 7 cm (2.8 in) wide, with rough branches.[4] Each spikelet is 1.9–2.5 mm (0.07–0.10 in) long; the lemma is 1.6 mm (0.063 in) long with an awn attached around the middle.[2]

Distribution and ecology[edit]

The range of Agrostis canina covers most of Europe and temperate parts of Asia, and extends from sea level to the alpine zone.[5] It has also been introduced to eastern North America, Hawaiʻi, Algeria, the Kerguelen Islands and South Georgia and the South Sandwich Islands.[1]

Agrostis canina is sensitive to drought,[5] but is common in damp places, including ditches and lake margins.[6]

The short, green growth of A. canina has made it popular as a lawn grass.[4]
