The originality of a terrarium depends on the type of container you use, the plants you choose and the way you arrange them.
Any glass container can serve as a terrarium, provided that it is transparent.
You can recycle a large glass jar, a fish bowl or an old aquarium. Alternatively, there are some very attractive containers made of wood and glass or plastic available on the market. If you wish to add a decorative touch, you can cover the soil with colored stone, bark chips or ground-cover plants.
