Pea Gravel is available as 3/8" and 5/8" native, washed gravel. This gravel has various brown colors. You can use pea gravel between flagstones to inhibit weeds, and provide a comfortable walking surface between the larger stones. Pea gravel adds a subtle textural contrast and the same long-lasting strength and durability as flagstones. It comes in shades of gray, white and neutral color and blends seamlessly into a landscape.
