Meadow foxtail, Alopecurus pratensis, is a native member of the grass family commonly found in a variety of habitats, including meadows and verges. It gets its name from the long cylindrical flower heads, which when they develop have pale flowers protruding, which can give the head a fuzzy look. These turn brown as they age and look like fox tails. It flowers between April and June, and can reach over a metre high. The leaves are slender and hairless.
Meadow foxtail is a food species for the caterpillars of the Essex Skipper Butterfly, but is also often grown in agricultural as a hay crop.
