The large moss is a species of Polytrichum, for what it's worth...

Hi
You're a brave man trying to identify these plants lol I grow Martinsii,uncinta and euryops on purpose and a whole jungle of things that come up with it. The most interesting is the driftwood that is kept constantly moist the selaginellas will attach but not nearly as well as the ferns
and that stuff that looks like green velvet,
i find the selaginellas will change habits and colors depending on the growing conditions and temps also ,I suspect. Martinsii in particular will range from almost a bronze color through greens and even blue looking much like incinta in the shade. You'd think they were different species Whatever they call them they are one of my favorite plants!! My "moss" garden is not quite a year old and it's
already fantastic to look at though I can see that ferns are going to be a big problem. gary
