Mayor Daley will participate Saturday in the Farm Dedication and Ribbon Cutting Ceremony of Uncommon Ground’s organic rooftop farm. The 2,500-square-foot farm, located above the Edgewater restaurant, is the first certified organic rooftop farm in the U.S. Uncommon Ground owners Helen and Michael Cameron use the farm to produce food for their Wrigleyville and Edgewater locations. “As a child we grew a vast array of fruits and vegetables. As a result, I’ve always enjoyed growing things,” Helen Cameron says. “The minute I saw this enormous, sunny space…I was like, ‘Oh my God, we could grow food up here.'” The farm was certified organic last October by the Midwest Organic Services Association. “To me, it’s perfectly natural to grow your own food in a small space,” Helen says. “We have a climate that works here in Chicago, and you can be very successful growing a great deal of food in the city.”
