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]
Poa [2] is a genus of about 570 species of grasses, native to the temperate regions of both hemispheres. 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.

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.
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.

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.
