Yum. A pizza shop goes through a lot
of these big tomato tins. One Toronto resident reused such cans from a local pizzeria and put them to re-use, creating a garden on an urban brick wall...
The cans are painted a bright blue and planted with white geraniums (top), white and violet verbena (middle) and petunias (bottom). Via: Sprig
