This quick fly-through by the Stefano Boeri Architects shows the lush vegetation of the Bosco Verticale, the vertical forest, in Milan, Italy. Mind you these are not CG renderings but the real deal. There are altogether 900 trees of over 90 species and over 20 000 plants in the two buildings. The plants and trees are taken care of by a single company. There’s also an interesting video showing how every 4 months these wall climbing botanists descend over the building and take care of the plants.
