Philadelphia is no stranger to urban bees. In fact, the city has been hosting rooftop beehives since 1914. It comes as no surprise that the most commonly used beehive model in the country was designed by a Philly native. With its East to West streets even named after trees like walnut, chestnut, and spruce, the city’s pollinators feast on a wide variety of white clover, linden trees, and Japanese knotweed.
