Poa annua aka Winter Grass

Poa annua, also known as annual meadow grass or annual bluegrass, is a widespread turfgrass found in temperate climates. Despite being called an annual, it can also be a perennial. This low-growing grass has light green leaf blades that spread horizontally from a central point, with shallow roots. It thrives in bare areas and produces pale, pyramid-shaped panicles of flowers that produce abundant seeds from early spring to autumn before dying off. Annual bluegrass can be identified by its leaf tip, which resembles a boat's bow. It is considered a winter-annual grassy weed that spreads easily through bird and human dispersal. Controlling Poa annua can be challenging and may require specialized products and properly-timed applications, especially if non-selective weed control is the only option for certain turf species.
