In 1906, industrialist Pierre du Pont (1870-1954) purchased a small farm near Kennett Square, Pa., in order to save a collection of historic trees from being sold for lumber. Great-grandson of DuPont chemical founder Éleuthère Irénée du Pont, Pierre soon used his family's fortune to develop an extraordinary, private garden and fountain collection, drawing inspiration from world fairs and European gardens. In 1931, Pierre debuted the Main Fountain Gardens and wowed spectators with 380 fountain heads, a recirculation system of 18 pumps that propelled as much as 10,000 gallons of water a minute, a 50 foot waterfall and fountains that burst water 130 feet into the air. Although, after 83 years of use, it was time to breath some life into the gardens, as some of the features had become dilapidated and antiquated. So, on September 25, 2014, Longwood Gardens announced that it would embark on a series of major improvements to replace the 83-year- old fountains' infrastructure with the latest technology to improve guest enjoyment and honor the visionary design by Pierre S. du Pont. The entire construction period lasted nearly four years and cost $90 million. Middle: A new type of fountain featuring a flame at the top of the water column was installed. This fountain feature, known as a "Flame Nozzle," was designed in Germany and is able to erupt a foot-high flame ontop of a 10-foot tall water jet. The flame is carried from the base of the jet to the top of the fountain through little air bubbles in the water. If it is too windy, the flame and the water jets can be scaled back or turned off completely. In total, 30 flame nozzles were installed. Above, Left: One of the major additions to Longwood Gardens was a subterranean tunnel system. This system allows easier access for maintenance, because in the past, if anything malfunctioned, repair crews would have to dig down to find and fix the pipe or electrical wiring. This new 1,400 linear feet tunnel system houses 51 tons of copper wire (10 miles) and 5 miles of fountain piping. To make this possible, 100,000 cubic yards of soil had to be moved and redistributed. 30 Landscape Architect and Specifier News "To see the Gardens at night is to be taken to another planet." — Jim Garland, President of Fluidity Design Consultants
