Peat mosses are mosses typically found in dense, water-saturated peat bogs. They play a crucial role in their habitat by retaining moisture, supporting the bog ecosystem. These plants have a spongy texture, with specialized cells that are effective at absorbing and holding large volumes of water. The color can range from green to deep reds, allowing these mosses to be easily recognizable in their environments. Their ability to form extensive mats also helps in stabilizing the bog surface.
