I don't have much of a green thumb, but these plant canvases from Flora Grubb Gardens are pretty freaking awesome.
These must be really slow growing plants or else the art wouldn't last very long on your wall. And how do you water it? Spray it with a water bottle? And do you have to remove a few every now and then to allow for growth?
Alls I know is it looks really cool. And, of course, I want to make one.
