Made from authentic rainflower stones in a mix of warm sandstone, gray, and earth-tone shades, this 15 lb. bag of 1-2 in. natural multi-color river rocks brings a varied, organic look to pots, aquariums, walkways, and decorative water features. Each pebble is tumbled and polished smooth with no sharp edges, protecting plant roots from scratches and keeping your hands safe during placement. Multi-color tones rather than single-shade dyed stones mean every installation has natural variation that mimics a real river bed — buyers who want a uniform machine-cut look may prefer single-color options, but for landscape designers and aquascapers wanting authentic mixed stone, this is the right pick. Layered at the bottom of pots, the stones improve drainage and prevent root rot in moisture-sensitive plants. Spread on top of soil, they retain moisture through summer heat and block sunlight from weed seeds trying to germinate. Authentic rainflower stone composition resists fading, corrosion, and degradation — natural colors stay rich through years of outdoor sun and rain, with no dye leaching into soil or aquarium water. Each stone measures 0.59-0.71 x 0.59-2.36 x 0.19-1.97 in., and the bag weighs 14.99 lb., light enough for one-person carrying from car to garden. Tip: rinse stones thoroughly before aquarium placement to remove surface dust.
