Stiff clubmoss is a slow-growing, evergreen ground-cover plant of cool boreal and montane forests, requiring consistently moist, acidic, humus-rich soil and dappled shade to survive. It is notoriously difficult to establish in cultivation because it depends on mycorrhizal fungi associations and precise environmental conditions found in undisturbed forest habitats. This plant is best suited for experienced native plant enthusiasts attempting naturalistic woodland garden designs.
