Some of us have them in our yards. Blue is the suggested colour to use for the glass bottles. Makes sense in terms of what it signifies in African spirituality. Think: Auset/ Yemanja.

I’ve rarely seen a bottle tree where I live. I’m more inclined to see coloured bottles around the perimeter of folks’ yards. It’s all part of the same bottle tree tradition. Ancient wisdom. Some folks use a variety of colours (for all the orishas). Here’s a little history & more:
P.S.- I know of a woman who recently purchased a glass bottle wind
chime for her home. She said the effect has been AMAZING. It has helped bring peace to her home and family. Check out http://www.thebottlebenders.com.
