I have some of it growing on old carpets ,outdoors , hence possibly ,, Carpet Moss ,, couldn't be , that graphic to name ,,
A good way to grow moss , (this one anyway ) peck it clean . mix it with buttermilk , sweet milk ,, , put a little on a few old cement or asphalt blocks , Put the towel down on the blocks , Dirty it a bit and weight it down slightly ,, poof moss everywhere ,,
What is charged for it is extreme ,,,
Also I dug out a compost bin type worm bin once , covered it with a wooden board cover , Had Giant Sphagnum growing over a foot tall for a while ,, looked like Ferns ,, was cool looking
