I found this cobalt Bottle Garden not far from my home.There is a traditional Bottle Tree at the far end. With over 400 bottles/glass pieces in her garden, some have inevitably self-seeded across the street.

Bottle Trees were sometimes placed near the entrance to the house, so the spirits did not enter the house with you. The spirits would become mesmerized by the play of the sunlight through the colors of the glass, and become trapped inside the bottles.
Quick tip: To remove labels, place wine bottle into pre-heated oven for 10 minutes. Use a spatula to lift up one corner of the label, and it will easily peel off taking most of the adhesive with it. You may have just a smidgeon to wash off.
