I love some of these green ideas. Seriously when I took them, I didn't think much about them.
But looking at these 4 photos, 1 of them does not fit in again. Guess which is that? It's the second photo because it is one of a rooftop garden. The other 3 were vertical displays of plants!
The third one can be seen at HortMart. The fourth one is a good DIY idea on sale at Far East Flora.
I love the first one the most because of the variety and randomness of the plants that caught my attention. But seriously, is it really sustainable? If it is, I would love to try it at home.
