Poa annua is a common annual bluegrass species that frequently appears as a weed in golf course greens, fairways, and sports fields. Poa annua is known for its ability to thrive in cool, moist conditions, but it can become problematic due to its tendency to produce seed heads, creating uneven surfaces and weakening the turf's overall quality. It is often managed through overseeding, herbicides, or mechanical practices.
