A few years ago, I remember going to MOMA and seeing an exhibit about a future project called “The Highline”– fast forward a bit and now it’s a reality! I think it turned out great. I loved how they weaved the plants with the structural elements. 
One thing I especially loved were these benches that had a built in planter in the back!
Looks like they still have a bit more to construct before it’s officially completed- so definitely something to look forward to on my next visit. I hope more places like this start popping up in urban settings. If you haven’t been yet, definitely check it out- More info here.
