Semiahmoo Public Library Green Wall
November 3rd, 2010 | Posted by in LushePatrick Poiraud from Green over Grey Designers emailed in some photos of a vertical garden they have just completed at Semiahmoo Public Library in Canada. According to Patrick, it is “the largest and most biologically diverse outdoor green wall in North America”. It is located in Surrey, Canada, covering the Semiahmoo Public Library and RCMP Facility.

The 3,000 square feet design incorporates over 10,000 individual plants representing more than 120 unique species. It includes ground covers, large perennials, shrubs and small trees. The large diversity of plant species chosen creates a balanced ecosystem that is an urban oasis for bees, butterflies and hummingbirds.
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.
We look forward to seeing the living wall in a years time when it has fully developed.

Very impressive.
Please explain how the wall is watered
Looks nice!!
it will be very interesting to follow in warm summers and cold winters. It looks a lot like the french Patrick Blanc system which is in Europe not performing well under severe circumstances. I hope your wall will be succesfull!!
looks great – hope it works
I am curious to know if the water is recirculated.
It looks amazing!
Nice to see a wall used to decorate a library and it was also fun running into you, Bob, at Fairchild Tropical Botanic Garden on Saturday. Seems like you have been up to some very interesting good things lately. Nice catching up with you. Keep growing ! Diane Rourke (retired librarian, Miami native)
