miniature garden on coal

I have green thumb.
Plants grow for me, gifting me with their changes, vigor, naps, taste and tickles. nutrition.
I attempt to push the boundaries of where and on what the plants will grow...
A latest great success with such experiments is to grow plants on a pile of coal. Yes, coal from the mountain. A miniature isle of a garden, many folks may miss it - but those who hone on it get a treat. I don't think we will eat this one just give it a good old gander.
This pile and garden are part of my current exhibit in Miami at Dimensions Variable.
