Rough bluegrass (Poa trivialis)

Rough bluegrass (*Poa trivialis*) is a perennial grass well-suited to cool, moist environments. It commonly inhabits floodplains, forests, meadows, fields, and the edges of rivers and lakes. This grass is notable for its flowers, which appear from late winter to early spring. Unlike Kentucky bluegrass, rough bluegrass is distinguished by its rougher sheaths, giving it its name.
