I stumbled upon this unique urban gardening along the roof top of an outside mall in Insadong (the arts and crafts area of Seoul). I love that you can grow a pepper plant out of a sand bag. If I ever get a roof top patio, which is on top of my apartment wish list for next year, I'm going to try this out. Many apartments have patio areas so I'm keeping my fingers crossed.
I'm so impressed by the eggplant plant. The corn on the other hand doesn't look so hot. The brightly colored sandbags definitely add to the display.
