Poa infirma

Species of grass

Poa infirma is a species of grass known by the common names early meadow-grass[1] and weak bluegrass. It was first described from a specimen found in Colombia, but it is actually an introduced species in the Americas and is native to Europe.[2] It grows in many types of habitat, including disturbed areas. It is very similar to Poa annua, which is probably a daughter species,[2] and it is often mistaken for P. annua unless it is closely examined.[3]
