Anyway, wanting to do something a little different with my plants, I gave it a go, with excellent results.
I found the glass dish at the Salvation Army for a couple bucks. This one is my favorite.
I had this one under the skylight in the bathroom, but the cats were too interested in it so I had to move it somewhere less prominent. Luckily, the fern will tolerate low light.
This terrarium is keeping it simple with a piece of driftwood and soft green Kalanchoe.
