Or so says Patrick Blanc in Vertical is the way to go, an interview with Margaret Kemp (FT).
Living in the city can deprive us of greenery.
Patrick Blanc is known for his Vertical Gardens, using buildings as his canvas.
Anna Lambertini a professor of landscape studies at Florence University and Jacques Leenhartdt Director of Research at École des Hautes Etudes en Sciences Sociales in Paris illustrate his creations and the work of others in their book Vertical Gardens: Bringing the City to Life.
They remind us that "Vertical gardens are an exciting means of bringing life and greenery to
a bleak courtyard, a grey city street or a cold modern building".
Ruth Slavid reviewed the book for The Architect’s Journal (UK) in December 2007.
