The Montreal Botanical Garden is considered to be one of the most important botanical gardens in the world due to the extent of its collections and facilities. The 190 acre big grounds are comprised of themed gardens and greenhouses featuring plants from all over the world.
In 2013 the gardens were holding the international Mosaicultures exhibition where competitors from around the world created giant living “sculptures” using plants as their medium. Each sculpture has a wood or wire framework filled with a growing medium through which a watering system was installed. Carefully selected plants were placed in the frames, grown over time and pruned to perfection.
The photos featured here were taken in summer 2013 and with the exhibition being over now I'm not sure how many (if any) of the sculptures would still be there, as it takes insane hours and around 80 gardeners to maintain them.
