North America’s Largest Indoor Living Wall
Pennsylvania's Longwood Gardens now hosts one of the largest green walls in the world.
Last week saw the unveiling of North Americaâ€™s largest green wall in Pennsylvania’s Longwood Gardens. Designed by Kim Wilkie and installed in the garden’s new East Conservatory Plaza, the green wall measures over 4,000 square feet and hosts a mind boggling 47,000 plants. The wall’s maintenance is fully automated with remote operated irrigation and sensors to ensure a long life for plants and will act as a green lung for the conservatory by removing over 15,000 lbs of toxins each year from the environment.
