Since its first exhibition in 1829, the Pennsylvania Horticultural Society (PHS) has introduced beautiful new plants, inspiring design concepts, and innovative environmental practices to the American public at its annual show. Having begun as a modest display of fruits, vegetables, and flowers in a 19th-century Masonic Hall, the event expanded into the Philadelphia Civic Center, later completed a 21st-century transformation of 10 acres in the Pennsylvania Convention Center, and blossomed into the world's largest indoor horticultural event--the PHS Philadelphia Flower Show. Today, the nine-day celebration of astonishing gardens and superb floral and landscape design attracts a quarter-million visitors to the city.
