Annual Meadow-grass is a low-growing grass which is a light green colour. It grows from a central base, to which all the shoots can be traced, and has a creeping rootstock. It flowers throughout the year, but is most prolific in spring. As with certain other vigorous grasses, it can become a nuisance on agricultural land and these species are often considered to be weeds.
The blade-like leaves are blunt-tipped.
The yellow-green flower head is triangular with branched spikelets that contain the flowers.
Annual Meadow-grass is a very common, short-lived grass found in bare grassland, on disturbed ground and waste grounds, and even in turfed lawns.
