Green walls are a relatively new concept that comes in many sizes and shapes. Living walls incorporate a vertical growing support matrix that allows plants to be rooted anywhere on a building’s wall surface versus a green facade that trains vines to grow up a trellis or other support system. Nature has perfected the art of living walls since the beginning of time. Plants have shown that soil is not essential for a vertical landscape in nature. Living walls reduce heat island impact, stormwater runoff, and make walls beautiful.
