caption_attribution_description: English: en:Bluegrass stem showing why it's called "bluegrass." The seed pods go from green to purplish blue to brown. During the purplish phase the stems also appear to be navy blue. Photo by poster in October 2007. NOTE: I believe this is en:Poa trivialis. This was photographed in a swampy shaded area next to a golf course in October. Any help on identifying it would be appreciated.
context_page_description: Poa is a genus of about 500 species of grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass, bluegrass, tussock, and speargrass. Poa is Greek for "fodder". Poa are members of the subfamily Pooideae of the family Poaceae.
  Bluegrass, which has green leaves, derives its name from the seed heads, which are blue when the plant is allowed to grow to its natural height of two to three feet.
  The genus Poa includes both annual and perennial species. Most are monoecious, but a few are dioecious. The leaves are narrow, folded or flat, sometimes bristled, and with the basal sheath flattened or sometimes thickened, with a blunt or hooded apex and membranaceous ligule.

Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. Poa (πόα) is Greek for "fodder". Poa are members of the subfamily Pooideae of the family Poaceae.
  Bluegrass, which has green leaves, derives its name from the seed heads, which are blue when the plant is allowed to grow to its natural height of two to three feet (0.6 to 0.9 meters).
  The genus Poa includes both annual and perennial species. Most are monoecious, but a few are dioecious (separate male and female plants). The leaves are narrow, folded or flat, sometimes bristled, and with the basal sheath flattened or sometimes thickened, with a blunt or hooded apex and membranaceous ligule.
