DescriptionAgrostis canina is a perennial plant, with stolons but no rhizomes, and culms which grow to a height of up to {{convert|75|cm}}.[4] 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.[3]The leaf blades are {{convert|2|-|15|cm|1|abbr=on}} long and {{convert|1|-|3|mm|2|abbr=on}} wide,[6] with an acute or acuminate ligule up to {{convert|4|mm|abbr=on}} long.[4] The plant flowers from May to July,[3] and the inflorescence is a panicle {{convert|3|-|16|cm|abbr=on}} long and up to {{convert|7|cm|abbr=on}} wide, with rough branches.[6] Each spikelet is {{convert|1.9|-|2.5|mm|2|abbr=on}} long; the lemma is {{convert|1.6|mm|abbr=on}} long with an awn attached around the middle.[3] Distribution and ecologyThe 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, Hawai{{okina}}i, 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.[7] References{{Commons category|Agrostis canina}}1. ^1 {{Cite journal | author = Lansdown, R.V. | title = Agrostis canina | journal = The IUCN Red List of Threatened Species | volume = 2014 | page = e.T167861A42382326 | publisher = IUCN | date = 2014 | url = http://www.iucnredlist.org/details/167861/0 | doi = 10.2305/IUCN.UK.2014-1.RLTS.T167861A42382326.en | access-date = 5 January 2018}} 2. ^{{Cite book|url=http://www.forest.go.kr/kna/special/download/English_Names_for_Korean_Native_Plants.pdf |title=English Names for Korean Native Plants |publisher=Korea National Arboretum |year=2015 |isbn=978-89-97450-98-5 |location=Pocheon |pages=344 |access-date=25 January 2016 |via=Korea Forest Service |deadurl=yes |archiveurl=https://web.archive.org/web/20170525105020/http://www.forest.go.kr/kna/special/download/English_Names_for_Korean_Native_Plants.pdf |archivedate=25 May 2017 }} 3. ^1 2 3 {{cite book |author=Ann Fowler Rhoads |author2=Timothy A.
