Green roofs are quickly becoming a standard for improving building energy efficiency and managing storm water run-off. Chicago became a green roofing hub during the Daley administration, and Toronto now mandates them for new buildings. But, unless a building owner has plans for a rooftop garden (and the care required for it), a green roof requires plants that can thrive under hot, dry, and sunny conditions. Farmer and management consultant Ed Snodgrass saw an opportunity here, and, in 2004, expanded his wholesale nursery into the green roof plants niche.
