The hardiest of all the Vallisneria. Grows tall, dark green, straight leaves. These make an excellent background for any size tank as they can grow up to 3 feet tall! They will be limited by the size tank they are in. Its also safe to prune the plant at your desired height. The white base should be left exposed when putting in your substrate. We recommend planting in a nutrient rich substrate to help promote growth. CO2 is not necessary but will help plant to reach its full potential.
