This picture is another example of Xeriscape landscaping and gardening. This photo shows how we used two different types of river rock to add interest and contrast. Curving designs are always a good choice in landscaping. They mimic nature and gently lead the eye along the entire landscape. The brick edging we installed also helps with this visual aspect. The large rocks serve two purposes. Firstly, they create a dramatic impact. Secondly, they give the landscape a three-dimensional quality. This helps to prevent the landscape from appearing ‘flat.’ The plants of varying heights and widths also help to achieve this.
