Woolly Fringe Moss like to have its rhizoids in substrate, humid, that's how it can withstand direct sunlight, like Golden Head moss or Haircap mosses, which gives it the amazing look even in full sun.
Grows up to over 20 cm but you can easily trim it, either from the top or from the bottom.
It can survive well without watering, when dry it turns white, and after watering the colours are coming back.
It's good for any conditions. One of the most robust moss families. ( Racomitrium )
