Designing your Garden with a large rock element is a simple way to create a focal point.
The more knarly the shape, the bigger the holes and using large scale can add a unique natural element to your garden.
Color differences can be attractive and add interest if you can find.
Larger shape and scale are a landscaping factor, as too small rock display will get hidden or over grown by future tree and plant growth.
Rock Landscape Photo is a good example, it is knarly, sizable and has some color contrast … good luck in your rock hunt.
