Poster pocket plants

Continuing the urban gardening theme around here (earlier: seed bombs, guerrilla flower boxes, tube gardens), here's a clever bit of green billboard reclamation, pointed out by Tyler Green. Toronto residents Eric Cheung and Sean Martindale have devised a way to cut advertising posterboards to make cone-shaped, in situ flowerpots. Martindale tells Torontoist that the duo is "activating public space," introducing nature "to the urban environment in ways that might encourage others to do the same, or to at least consider such possibilities." To that end, they've made the design of their templates available under Creative Commons license.
