So you have a beautiful container and bought a lovely little plant for it. What can you do to give it some decorator magic? With just a couple of dollars and a quick trip to your local arts and crafts store, you can purchase moss and make that plant a standout! There are various types, but I like this green moss for smaller houseplants. For larger ones, I use the gray sphagnum moss. I can fill two very large houseplants with that for about $7.
