Racomitrium lanuginosum, commonly known as woolly fringe-moss or grey-green moss, is a hardy cushion-forming moss suited to cool, moist, and open environments. It performs best on rocky, acidic substrates in bright indirect or diffused light and requires no fertilizing or pruning. Keep it consistently moist with soft or rainwater and avoid hard tap water, which can inhibit growth.
