We passed by these flower pots this morning and had to share. Circle-shaped holders for clay pots are welded to the balcony railing and pots are nested down in to create a plant-filled border... The balcony is located on a corner apartment and these blooming pots fancy it up beautifully. Repeating clay pots dancing around the rail are much more appealing and playful than typical long window boxes. This is definitely a retro-fit by the apartment's owner, as identical balconies on the same building have no pots or pot holders.
