Vertical gardens are becoming popular as more and more of the world’s population lives in urban centers. Patrick Blanc has built the world’s tallest vertical garden in Sydney, Australia, with over 450 plant types, of which 250 are local plant species. Blanc learned to make vertical gardens as a child, once he understood that plants don’t need soil; they can grow in water, absorbing nutrients while also filtering the water. According to Blanc, vertical gardens afford a more complete view of all the plants when compared to a horizontal garden. Trained as a botanic scientist, Blanc is able to match plants to their preferred climate easily; this makes him a more time-efficient vertical garden creator compared to competitors.
Offering opportunities for showcasing architectural creativity, vertical gardens can be quite beautiful. Importantly, aside from being esthetically pleasing and well suited to urban populations, vertical gardens also help in “reforesting” urban landscapes, providing fresh air and humidity. Research also shows that vertical gardens can play a role in adapting to climate change through their cooling effect in office buildings.
