Poa annua, or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. [2] This grass originated as a hybrid between Poa supina and Poa infirma. [3]

Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. Poa is Greek for 'fodder'. Poa are members of the subfamily Pooideae of the family Poaceae.
British NVC community OV22 (Poa annua - Taraxacum officinale community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities characteristic of gateways, tracksides and courtyards. This community occurs very widely throughout Britain. There are three subcommunities.
Magnaporthe poae is an ascomycete fungus which causes the turfgrass disease commonly known as summer patch, or Poa patch. [2] The disease occurs mostly on Kentucky bluegrass (Poa pratensis), Fescues (Festuca sp.), and on Annual bluegrass (Poa annua). [3] Bentgrass (Agrostis sp.) may also become infected but shows very few symptoms and quickly ...
British NVC community OV20 (Poa annua - Sagina procumbens community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities characteristic of gateways, tracksides and courtyards. [1] [2] This community is widely distributed in the lowlands and upland fringes of Britain.
The BOP clade (sometimes BEP clade) is one of two major lineages (or clades) of undefined taxonomic rank in the grasses (), containing more than 5,400 species, about half of all grasses.
British NVC community OV12 (Poa annua - Myosotis arvensis community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of eight arable weed and wasteland communities of fertile loams and clays. It is a widespread community, in which two subcommunities are recognised.
