Polytrichastrum formosum, commonly known as bank haircap moss, is a robust terrestrial moss ideal for shaded woodland gardens, terrariums, and moist rockeries. It requires consistently damp conditions and thrives under indirect light or dappled shade, making it unsuitable for hot or dry environments. Use rainwater or distilled water where possible, as it is sensitive to the minerals and chlorine found in tap water.
