I was amazed at my last trip to San Francisco in June that from our hotel view (Mission and 4th St.; near the Metreon and close to Market Street) seeing two rooftop gardens with bamboo planted. Why? Rooftop gardens help cool the floors beneath, helping to reduce cooling bills and reducing CO2 emissions. The challenge for most urban rooftops is to have some afternoon shade to protect the plants and you also have to deal with high winds. In San Francisco's case, having temperate weather all year long helps accommodate a wider range of varieties. Here is a photo of the view from our room.
