An amazing exhibit of Mosaiculture, including this living sculpture of Hachiko, the Loyal Dog, can be found at Montreal Botanical Garden this summer. I saw this article on Houzz, where it was noted that:
It's not an invasion from the zoo — it's mosaiculture, a type of horticultural art as wild as it sounds. Mosaiculture designers install carefully selected and pruned plants onto two- and three-dimensional designs, creating massive and surprisingly realistic living sculptures. In this exhibit visitors walk along a 2-kilometer (1¼-mile) path to see the work of 50 participants from more than 20 countries. Each designer worked with a set plant catalog to sculpt something from his or her country's culture.
