Blanket bog, which forms on the highest land where the rainfall exceeds a year, consists mainly of cotton-grass (Eriophorum species), sedges (Carex and Rhynchospora), Bog Asphodel and Common Tormentil, with Sphagnum thriving in the wettest patches. The valley bogs have lush growth of rushes, with sphagnum, cross-leaved heath, sundews and several other species.
