Wall screw-moss is a small, cushion-forming moss that naturally colonizes stone walls, rocks, and masonry in cool, partially shaded conditions. Keep the substrate evenly moist with regular misting and avoid prolonged drying out, though it can tolerate brief dry periods. It makes an attractive addition to terrariums, fairy gardens, or decorative moss walls indoors.
