Ctenidium molluscum is a feathery pleurocarpous moss that thrives in cool, shaded, and consistently humid environments. Keep it away from direct sunlight and maintain high ambient moisture by misting regularly or placing it on a humidity tray. It is an excellent choice for terrariums, moss gardens, or woodland-style arrangements.
