How to Grow and Care for Living Stones

Living stones (Lithops spp.), also known as pebble plants, are unusual little succulent plants that have evolved to look like the pebbles and rocks of their native habitats in Africa.These plants hug the ground and grow extremely slowly. Living stones grow best in conditions that mimic their natural habitat, especially when it comes to providing light and water.
