Pond plants are aquatic plants that grow in or near ponds and other bodies of water. Common pond plants include algae, lilies, reeds, and waterlilies. Algae is a type of plant that grows in water and can range from single-celled organisms to complex multicellular forms. Lilies are flowering plants that typically have large, showy flowers and long, broad leaves. Reeds are tall, slender grasses with hollow stems that grow in shallow water. Waterlilies are floating aquatic plants with large, round leaves and beautiful flowers that bloom above the surface of the water.
