A perennial grass growing in a wide range of moist or dry, neutral and calcareous grasslands. It is found in meadows and pastures, on roadsides and railway banks, in open woodland and rides, coastal cliffs, fixed dunes, mildly acidic grassland over gravel, and some less acidic heaths. It tolerates modest mowing, grazing and manuring, but not artificial fertilisers or competition from vigorous fodder-grasses. 0-550 m (Moor House, Cumberland).
Although H. pubescens is now known to be much more frequent than when mapped in the 1962 Atlas, there have clearly been some losses throughout its range.
European Temperate element; also in C. Asia and widely naturalised outside its native range.
