High Quality Content by WIKIPEDIA articles! Poa annua, or annual meadow grass, is a widespread low-growing, tufted, annual plant in temperate climates. 'Poa' is greek for fodder. It is one of the sweetest grasses for green fodder, but less useful as hay. This grass may have originated as a hybrid between Poa supina and Poa infirma. It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm high. It is slightly flattened. The panicle is open and triangular shaped, 5 to 7.5 cm long. The spikelets are stalked, awnless, 1 to 2 cm long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with finely serrated edges. Occasionally the leaves are serrated transversely.
