PolyPebbles weigh less than half the weight of normal pebbles. They provide an elegant, professional finish as a top dressing for potted plants and will never rot, age, or discolor like Spanish moss.  PolyPebbles, which are made out of 100% recycled material, are ideal for use in waterfalls and fountains, for crafts and home décor, as well as for interior and exterior plantscaping applications. They are also great for vases as they sink in water.
