To follow up? I think this might be the best moss to grow. Its faster than Java,and it does not seem to fall apart as Java likes to do. I've already taken cuttings and those are growing very well,the original clump has covered the wood..albeit not a large piece,with lush dark green moss.
Some great newby plants are out there and yet few people know of them..this is a great first moss to try. Use iron!
