Mosses are a separate division within the plant kingdom with over 100’000 species and are found all over the world. Mosses grow slowly but consistently. They can collect the essential nutrients from the rain and mist and don’t need soil and can thereby colonize places where so called higher plants can’t grow at all. Their robustness against harsh conditions was crucial during their evolution as they greened our planet approx. 470 Mio years ago.
