Poa annua L., commonly known as annual bluegrass or meadow grass, is a species of turfgrass that has been distributed from Europe to every continent including regions of Antarctica. It has flourished as a winter annual, germinating at the end of summer, maintaining a tall, coarse vegetative growth during the fall and winter, and ending its life cycle in the spring with a prodigious seed set. It lacks the characteristics of a sustainable turf such as heat and drought tolerance and disease resistance. However, fairly recently on an evolutionary time scale, a new biotype of Poa annua has evolved. The "greens-type" has transformed its life history traits to a perennial type grass exhibiting prolific tiller density, with a dwarfed stature and fine leaf texture. The additionally traits; tolerance to heat and drought, and resistance to anthracnose, pink snow mold, and dollar spot also vary among greens-types. This biotype of P. annua can be found on older elite golf course putting greens, flourishing under mowing heights of a 1/10th of an inch and thus produces an extremely fast, uniform playing surface. In 1927, Piper and Oakley described the perennial, greens-type's utility in a letter from the USGA; "The perennial type provides a dense uniform playing surface ideal for putting greens."
