When space is limited or there is no available free soil or ground, container gardens are an attractive and successful substitute for beds. This style usually implies a small space or courtyard limited by the denseness of an urban setting. Containers can be easily moved around for a change and take up very little space. Vary the sizes and shapes of pots, try to group them in different positions and size., plant contrasting textured plants together or complementing colors for exciting plant and container arrangements even in the smallest spaces.
