I'm not sure what floral moss is. I first make a mush from 2 oz of whiteglue, 8 oz water, and green paint in a blender. I then add paper towel, McDonalds bags, and newspaper to make a thick pulp which I spread about 1/2 inch thick. I then add turf flocks, home made ground foam, commercial ground foam, green poly-fiber, clump-foliage, caspia, deermoss, lyken, trumpet vine roots, sticks from the woods and yard, paint brush fibers, dirt from the gutter, sand, whatever looks good. I then wet it down with alcoho; based wet glue and wait overnight for it to dry. I like lots of genetic diversity as I think it makes things look better than using a lifelike grass matte or all one color flock. I attacked a pic of another area from my layout that's my favorite so far.
