Although local, it often forms substantial pure
patches where it occurs. Notes on its habitats in Cornwall are
as follows. Grows on acidic soil and plant-litter, extending
over edges of rocks and fallen dead wood. Occurs mainly on
slopes or banks in deciduous woodland, sometimes on wooded
streambanks or under trees on laneside banks. Especially
common in Sessile Oak woods on hillslopes, but also recorded
in mixed deciduous woodland with much Beech, in larch
plantation and at edge of grove of planted Douglas Fir. One
record among low granitic rocks on hillside with acid
grassland and Bracken. Unusual records on dry and wet walls of
ruins of china-clay 'dries', slightly to well shaded by Grey
Willows. On almost unshaded soil at base of low mortared wall
on old mine area. Well grown patches on bark 0.5 m up trunk of
Grey Willow in open scrub among ruins of china clay dry. Also
patches on old copper mine-spoil in open on N.-facing slope
near edge of scrub.
