A perennial herb of damp meadows and pastures on a wide variety of soils, only avoiding very dry or acid conditions. It is a characteristic plant of unimproved hay and water-meadow communities, and now of relict herb-rich fragments on damp road verges; it also grows on dune grassland, in montane flushes and in tall-herb communities on rock ledges. It is unpalatable to grazing animals, but easily controlled in intensively managed pastures. 0-1220 m (Cairntoul, S. Aberdeen).
The distribution of R. acris is stable.
Eurasian Wide-boreal element, but naturalised in N. America so distribution is now Circumpolar Wide-boreal.
