"Longwood Gardens in southeast Pennsylvania has established the largest green wall in all North America.
The idea for the green wall started as a sketch on a cocktail napkin. Longwood desired a grand new entrance to the East Conservatory Plaza. And, because they handle almost one million visitors a year, there was also a need for more restrooms. The result is a curving structure with 17 restroom pods strung together. The walls consist of 3,590 modular panels mounted on a steel framework. Each panel houses a carefully selected variety of plants, about 47,000 plugs in total. The plants are fed by drip irrigation of water enhanced with liquid fertilizer.
The living walls which have multiple water benefits help connect visitors with plants, dampen noise in the area, provide moisture and oxygen to the air, and moderate the temperature of the microenvironment in that area. Green walls are one of the tools used by architects and planners to create more sustainable communities. Depending on the design and whether they are indoors or outdoors, green walls can enhance the water environment by slowing down a significant amount of stormwater runoff, resulting in healthier streams. Green walls can also be a way to reuse grey water, such as wastewater collected from washing and runoff from roofs. The plants can purify the water and the system can reduce overall water consumption."
