Artificial rock gardens are meant to replicate nature's stone landscapes. However, rocks serve a practical function in gardens, providing drainage and other benefits to the soil. Rocks are prominently featured in Japanese or Zen gardens - which are a seemingly random collection of rocks and moss on this simple gravel rectangle - represent the seven life events of Buddha.
Artificial rocks and authentic multi-colored pebbles also add color and character to plant and flower gardens as well as to fish ponds, fountains, in bird baths and waterfalls. In many cases artificial rocks will provide the perfect camouflage over cords and pumps. Large artificial boulders can provide a waterfall effect by your pool, pond or in a garden fountain. A 5-pound bag of colored rocks can be scattered around the base of a shrub, in a plant pot, in a fountain or bird bath for only a few dollars. Larger faux stones are made of cement and stained to a natural look. These cost from $5 to $10 each online.
