This is some blog description about this site
THE world's largest vertical garden can now be found in the heart of Singapore's Central Business District (CBD). Standing 19 metres high and 110 metres wide - as big as eight tennis courts - this green wall of plants belonging to Ocean Financial Centre is a curtain made up of 51,000 potted plants of 25 species. The pots have been arranged to make up a map of Singapore, South-east Asia and the world.
The wall serves a purpose beyond the aesthetic. It is designed to reduce the surface temperature of OFC's carpark, which sits behind the wall of green. It is also a green lung which filters out vehicular emissions and provides visual relief from the dense concrete landscape of the CBD.
Proprietary landscaping designs have been adopted to secure the pots of plants in place; an automatic irrigation and fertilisation system ensures minimal maintenance.
