The joy of gardening is that you can create landscapes for both large and small spaces. When it comes to small garden landscaping, you should think in terms of style, scale, form, color, repetition and fragrance. Small garden landscaping ideas can make a small garden just as much of a showcase as a much larger garden. For instance, choose smaller versions of larger plants. Many smaller varieties exist of plants or trees. These allow you to add more plants for size and color than selecting a few large plants or trees.
