Featherock Planters that are displayed with plants, succulents or herbs are a sure-fire item your customers will covet. Each volcanic stone is hand-picked and drilled with a 4- or 6.25-inch hole, ideal for container gardening or for planting directly into the stone. Each one has a drain hole, and the stone is chemically neutral. Featherock planters are a natural home to just about any kind of plant.
