Green landscaping company Vitaverde recently built this leafy vertical garden for the National Bank of Greece. The green wall (the first in Greece according to Vitaverde) popped up in Athens and offers bankgoers a soothing and cooling art piece to look at. “The project shows how even the most densely populated urban centers can be turned in to green oases using the right solutions and materials,” says Vitaverde of the verdant new project.
