The following species in the grass genus Poa are accepted by Plants of the World Online. [1] Speciation in this genus is marked by interspecific and even intergeneric hybridization events. [ 2 ]
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]
Many of the species are important pasture plants, used extensively by grazing livestock. Kentucky bluegrass (Poa pratensis) is the most extensively used cool-season grass used in lawns, sports fields, and golf courses in the United States. [14] Annual bluegrass (Poa annua) can sometimes be considered a weed. [15]
