It is green roof gardens that allow bringing vegetation into cities in a big way. The concept is surprisingly as simple as growing various plants up the outer walls and on rooftops. Remember one of the captivating wonders of the ancient world – Babylon Gardens?

Modern architects use concept of “Semiramida Gardens” allowing buildings to reduce heat island effects and to use less energy, saving on annual energy costs.

In the past green roof gardens were attractive and practical, but not edible.
This was until someone with a creative spark decided to make green roofs twice as useful and productive and use rooftop gardens as a source of fresh produce. Now green roof gardens are tied to restaurant businesses. And what could be more ingenious? The food that is used in exquisite culinary creations in the kitchens below grows right on the rooftops of restaurants all over the world!

Let’s take a look at some of the restaurants that implement green roofing produce in their everyday menus…

Uncommon Ground restaurant in Chicago has a 2,500 square-foot rooftop garden. The executive chef tells the Chicago Sun-Times: “We just used the peppers from the garden and stuffed them with chorizo. When things from the farm are ready, we’ll incorporate it however we can. I come up once a day to see what’s ripe and ready.”

Sun Works, the people who built the Science Barge – An Urban Farm that Floats and Grows in NYC, state that New York’s 14,000 acres of unshaded rooftop could feed as many as 20 million people a year, far more than the whole population of the city.
