Of all the many gardens I have visited with plants in containers, the most unique one that stands out in my mind is a garden in NE Portland. In this garden, the front of the house overlooks the roof of a garage. However, this did not stop the owner from creating a space completely filled with plants in containers. There are all sizes and colors of containers and by mid-summer the foliage and flowers have almost completely covered the pots they are planted in. Without prior knowledge, a visitor would never believe this is the roof top of a garage and that every single plant is in a container.
