Whether you are planning an entire rock garden, need to build a waterfall for your pond, or simply want to add some natural hardscape elements to your yard, there are plenty of options when it comes to landscaping rock. Big boulders, fist sized polished lumps and every size in-between, landscaping rock can be one of the elements to complete your vision of landscaping elegance. You know you want rock, and you have an idea of what to do with it, but do you know what kind of landscaping rock would suit you best? Below are four examples of rock and a little about them; knowing what options you have will help you when it comes time to write a check for your hardscape.
Schist is almost a family of rock instead of a type; it comes in a wide variety due mainly to its composition; nearly any mineral can be the predominant force in a schist rock. The word schist means “split” and refers to the long thin layers of minerals aligned in the rock. A healthy amount of schist rock could complement the flow of your garden beds, or the path of a stream or brook. Below are two more striking varieties of schist.
Blueschist can be very blue, or it can have a mottled blue appearance. It is a northern california rock, typically used in landscaping in walls or pathways for striking effect.
Greenschist has a color ranging from a coppery green to a gray green, a bold standout when used among more plain rocks. Some polished specimens can give a marble like look to a garden pathway, for example.
Serpentinite is the state rock of California. It is perhaps most striking in it’s larger, boulder sizes. It surface can be polished, and is typically blue and jade green. It is a seafloor rock formed by ocean compression and contains long crystalline fibers. This landscaping rock could make quite a statement as a showpiece.
Chert can have a variety of appearances, due mainly to what elements compose its make up. In some varieties it can have a striped appearance, standing out from planer river rock. A bed of black river rock and tan river rock with a smattering of black-stripped chert would make a fantastic floor for a koi pond. Other forms of chert, like those with a heavy clay base, would make great hardscape for a mid-western feel, with its blended, reddish composition.
Landscaping rock comes in almost infinite variety, just like landscaping plans. Taking the time to learn a bit about your rock will pay off in the long run.
