Plants for the background are primarily long-growing stem, rosette or tuberous plants that grow longer than the aquatic plants in the middle and foreground areas. In water plant aquaristics and in aquascaping, you have a great number of background plants to draw upon. Especially fine- or small-leaved plants are great for the use in the background of an aquascape, as their small leaves lend the overall layout a sense of depth. The size relations of these plants and the tank dimensions are more favourable for depth perception than those of plants with very large leaves. Many species of the genera Rotala and Ludwigia belong to this group and make great background plants. Ferns like Bolbitis heudelotii or the especially narrow-leaved, long-growing Eriocaulon sp. "Japan Needle Leaf" can also be a great choice for the background. Narrow-leaved, long Crypts like Cryptocoryne spiralis are also highly suitable for this area in an aquarium or aquascape.
