Pea gravel is typically 3/8″ in diameter with smooth, rounded edges caused by erosion and natural weathering. It goes by many names including CA16, pea stone, pea pebbles, pea rock, and pea stone gravel. Colors range from browns and grays to more eye-catching colors like red and blue- which can either complement or contrast landscaping and foliage depending on your desired outcome.
Affordability, size, texture, and color make it a popular landscaping gravel for above-ground projects. Since it has a smooth finish, it’s also regularly used for gravel paths, dog runs, playgrounds, patios, and as drainage gravel for underground projects, such as pipe bedding.
