The 2012 International Flower Show, which wrapped up last week, aimed to take visitors on a trip to Hawaii. The Philadelphia Water Department's display, however, kept it right here in Philly, demonstrating how green roofs, rain gardens and other green infrastructure can beautify our city while managing stormwater runoff that pollutes our rivers and streams. Scale models of some of Philly's most famous buildings show how green the city could be, earning the Pennsylvania Horticultural Society's Sustainability Award for the exhibit demonstrating the best use of sustainable gardening practices to the public.
