Our Grey Cobble is a consistently-shaped, rounded rock with a diverse palette of pale grey hues. This make it ideal for the use in pathways and borders and to create natural-looking water features. When exposed to water, they take on richer shades of color and brighten up your fountains or rock gardens. Besides their decorative use, they are also a durable and low-maintenance choice for xeriscape and water-wise gardening. Available in 6-inch and 1.5-inch sizes.
