This one became a birthday gift to a very good friend of mine last February. It is a beautiful specimen of Echeveria, "Topsy-turvy" (right) and Sempervivum (left). I made its home from a small brandy glass my mom had given me (I hoard glass now, for obvious reasons). It is rooted in fine, white sand and adorned with chartreuse reindeer moss (aka, lichen) and some tiny shells. It has a "beachy" feel to it.
After almost two months, this specimen is still quite happy in its home.
Tip: Spritzing the sides of the glass with a spray bottle will help keep the glass clean-looking and the water will seep down to the root systems slowly, which is the best way to water succulents. You can also spray the plant itself to give it a little shower and keep it looking nice, too. Click on the "Terrarium Care" section for more info.
