Totally unrelated post, but I think this is so cool. A French botanist creates plant walls that never need pruning, although it's unclear what is needed in regards to watering and feeding.
I love plants. Currently, I have about 12-14 potted plants in my apartment, and 2 vases of bamboo, and I am always looking for more fun pots. I do think the concept of a plant wall is a bit much, especially since it mentions that the botanist/artist has mold growing on his ceiling (now there's an experience I have no interest in repeating - mold in one's home), but I love the idea of bringing nature indoors.
