This is clearly taking the meaning of "Green Building" to a whole new level! You've heard of green roofs, but green walls? Yes, Pure Yoga on 86th Street has a green wall! They call it a "living wall", and it is indeed alive. All I can say is "cool"!
The 1000sf living wall is watered by a computerized irrigation system and trimmed every couple of weeks. While I'm sure it's not cheap to build and maintain a living wall, Pure Yoga seems to have come up with a great marketing ploy. The wall does not go unnoticed, someone seems to be taking a picture of it every minute. The plants will be changed in the fall to a heartier variety that can handle the NY winter.
