This common plant is found on grasslands, especially on neutral soils. It is found on moist, fertile soils, but avoids waterlogged, light or dry soils. The species forms dense swards leading to low botanical diversity.
It flowers from April until June - one of the earliest grasses to do so. Any survey work carried out in mid-summer may miss the grass as a result of this.
It can grow to a height of about 110 centimetres (43 in). The stem is erect or geniculate at the base, the sheathes being smooth and cylindrical. The leaves are about 5 millimetres (0.20 in) wide and hairless. Meadow foxtail has a cylindrical inflorescence with glumes about 5–10 millimetres (0.20–0.39 in) wide and spikelets about 4–6 millimetres (0.16–0.24 in) long.
Similarity to other grassland species
Alopecurus pratensis has two common relatives, marsh foxtail (Alopecurus geniculatus) and black grass (A. myosuroides). It is often confused with timothy (Phleum pratense). Timothy flowers later, from June until August. Its spikelets have twin hornlike projections arranged in cylindrical panicles, while meadow foxtail has a single soft awn.
