Common haircap moss (Polytrichum commune) is a robust, low-growing moss that forms dense, lush green mats in moist, acidic, shaded environments such as woodlands and bog gardens. It thrives with high ambient moisture and indirect light, making it an excellent ground cover for shaded garden beds or terrariums. Avoid alkaline soils and allow the medium to stay consistently damp for best results.
