Test Tube Garden
Terrarium Garden
Hanging Garden
These very creative displays were at the Northwest Flower and Garden Show last week. I like these small gardens and the layers of dirt visible through the glass. It makes you wonder how many things we have around the house that could be used for a planter. What would you use?

The reflection in the Terrarium Garden photo is brilliant! How about a glass teapot, with things growing out the top and spout?!
