In alpine locations "P. alpina" is often found growing with "Carex firma" (an alpine grass), "Bistorta officinalis", "Dryas octopetala", and "Pedicularis rostratocapitata". Here it most often grows in a "Caricetum firmae" plant association, part of the "Seslerion albicantis" (alpine bluegrass) plant community.
