Green over Grey Designers completed planting the largest and most biologically diverse outdoor green wall in North America in Ocotober, 2010. It is located in Surrey, Canada, covering the Semiahmoo Public Library and RCMP Facility.

The unique soil-free design is nearly 3,000 square feet and consists of over 10,000 individual plants representing more than 120 unique species. It includes ground covers, large perennials, shrubs and small trees.

?This will be our first large-scale green wall in Surrey,? said Mayor Dianne Watts in 2010. ?It will be a beautiful living work of art that will cover the existing concrete wall and provide many environmental benefits, including saving energy, reducing greenhouse gas emissions and creating a new ecosystem in the heart of Semiahmoo.?

?The large diversity of plant species chosen creates a balanced ecosystem that is an urban oasis for bees, butterflies and hummingbirds,? says Patrick Poiraud, Principal at Green over Grey – Living Walls and Design, the Vancouver-based company designing and constructing the wall. ?The living wall helps to insulate the building, purify the air and transforms the grey concrete into hundreds of shades of green.? ?The initial inspiration for this garden came from the artwork of the Coast Salish (including Semiahmoo) First Nations People? says designer and artist Mike Weinmaster of Green over Grey.
