A creeping, rhizomatous perennial of well-drained acidic or neutral soils, found in Quercus and Betula woods, open conifer plantations, hedge banks, on heathland, and under Pteridium. It is capable of spreading into damper grassland and is locally a troublesome weed of arable land. H. mollis tolerates occasional mowing or light grazing but is a poor competitor with more vigorous grasses. 0-580 m (Greygarth Fell, W. Lancashire).
There has been no appreciable change in the range of H. mollis since the 1962 Atlas.
