Almost any of our natural stone can be adapted for use as a bedding/garden wall. If stacking is the look you want we have several of our veneer stones with relatively flat surfaces that can be dry-stacked up to 12" to 18" to surround a mulched bed.
We also offer natural stones that are roughly square/rectangular that make great edging stones and of course we carry several sizes and colors of cobbles that are ideally suited as edging stones.
