The traditional window box pot is usually very one-dimensional. The pot either hangs out - giving your neighbours a nice view of your flowers, or hangs in - giving you a nice view of your flowers but your neighbours with a back view of nothing. The On the Edge pot by Michael Hilgers gives you the best of both worlds. The ingenious design takes a traditional pot and splits it in two. Each half is able to house a plant of its own with its own separate container. The pot is made from water-resistant polyethylene and can straddle any balcony up to 60 mm in thickness. The pot comes in a number of cool colours, but they are hard to find.
