Poa
Poa, or bluegrass, is a genus of monocotyledonous plants in the Poaceae family (grasses), subfamily Pooideae. This genus, which originated in temperate regions of both hemispheres, is now almost cosmopolitan in distribution. It comprises more than 500 species, making it the largest genus in the Poaceae family. It is the standard genus of this family.
These are annual or perennial herbaceous plants, varying in height from 5 to 150 cm, with panicle-like inflorescences, sometimes reduced to a single spikelet.
Bluegrasses are very common plants, widely found in meadows, and several species are cultivated as fodder plants or for turf. Some are weeds in crops and lawns.

Bluegrass has given its name to a region (Bluegrass region) in north-eastern Kentucky in the United States.()
