Rock

Decorative rock, cobble, boulders and river rock, by the yard and by the ton.

Rock is the most-used ground cover on the Western Slope for good reasons — it does not blow out, it does not need replacing every spring, and it does not need water. It also holds heat, which is worth thinking about before it goes against a south wall or around something that would rather not be baked.
