| Poa annua | |
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] Major chromosomal rearrangements after polyploidy have contributed to variation in genome size in Poa annua.[4]
