Fieldstones were properly named, because many of these stones were typically found in fields or open spaces instead of being mined out of a quarry [sources: Pulver, First]. These types of rounded stones tend to come in a random assortment of colors, though they're usually categorized by size for purchase [source: First]. These stones can provide a more eclectic feel to a garden.
Fieldstones are most commonly used as wall stones. Fieldstones that are sold as wall stones tend to be larger and provide more depth than a flagstone, allowing for more depth and dimension to the wall [source: Pulver]. These stones work well as free-standing walls or wall veneers, or to create a raised bed for a garden [sources: Pulver, First].
