“The vertical garden, designed by Patrick Blanc, is 4 storeys high and takes up one outside wall, overlooking the plaza. It has 15,000 plants from more than 250 different species and most of it is flourishing.
There is an irrigation system which seems to be ongoing, given the gentle mist of droplets that emanates from the garden. The architects said that they wanted to ‘create a very unusual encounter between the rough and the natural, …to incorporate nature so there can be the smell of a garden where you would not expect it.'”
