In addition to sanctifying subway advertising, Toronto-based street artist Posterchild does guerrilla gardening too. He posted some new photos of his latest project: flower planters built inside trashed and mostly unused distribution boxes for crappy free papers no one wants. Sadly, the flowers don’t last long.

Why? I can’t say. I suspect that the box-owners are enforcing their territory, making rounds or complaints, maybe claims of safety issues. Who knows? But I hope that they were taken by garden-loving individuals who were excited for the possibility of free planters, soil, or plants….That’s a much nicer thought than the whole thing being pitched on principle.

Posterchild laments that while the foliage is quickly cleared away, the trash and empty sidewalk-hogging newspaper dispensers are near cleaned up. Click the images above for a lush look at the “green graffiti.”
