What aquatic plants purify water? Here are 5 recommended species

Water pollution is one of the major challenges facing environmental protection today, and aquatic plants play a vital role in purifying water. By absorbing nutrients, heavy metals and other pollutants from the water, they help improve water quality. This article recommends five aquatic plants with notable water-purifying effects, in the hope of contributing to environmental protection.

Reed

Reed is a widely distributed aquatic plant belonging to the genus Phragmites in the grass family. Its root system is complex and reaches deep into the soil, enabling it to absorb organic waste, nitrogen, phosphorus and other nutrients from the water, effectively reducing the concentration of pollutants. The dense stems and leaves of reed not only provide habitat for the aquatic ecosystem but also promote the natural purification of water quality. In addition, reed can inhibit excessive growth of algae, helping to maintain the ecological balance of the water body.

Lotus

Lotus is a perennial emergent aquatic plant, with elegant flowers and leaves and a pleasant fragrance. Lotus not only has extremely high ornamental value but is also an excellent water-purifying plant. Its roots and leaves can absorb nutrients and heavy metals such as lead and copper from the water, while releasing oxygen to increase the dissolved oxygen content of the water. Lotus ponds often have clear water, which is inseparable from the water-purifying ability of lotus.

Water lily

Water lily is a beautiful aquatic plant with a lush root system that can absorb waste and harmful substances in the water, such as nitrogen, phosphorus and other nutrients as well as heavy metal ions. The leaves of water lily float on the water surface, providing shelter and habitat for aquatic organisms while also promoting the natural purification of the water body. The water-purifying ability of water lily is closely related to its growth characteristics, and it plays an important role in water quality improvement and ecological restoration.

Cattail

Cattail is a perennial marsh herbaceous plant with a well-developed root system that can absorb nutrients such as nitrogen and phosphorus as well as heavy metals such as lead and copper from the water. The dense stems and leaves of cattail provide a rich habitat for aquatic organisms while also promoting water purification. In addition, the cattail spikes can also be used as cut flowers or dried flowers, giving them a certain economic value.

Softstem bulrush

Softstem bulrush is a perennial fibrous-rooted emergent herbaceous plant. Its stems are tall, straight and verdant green, giving it ornamental value as well as making it an effective water-purifying plant. The root system of softstem bulrush can absorb nutrients such as nitrogen and phosphorus from the substrate, reducing the pollutant content in the water. At the same time, its tall, straight, green stems are often used for water surface greening or as waterside accents, adding a touch of brightness to the waterscape.

All five aquatic plants above have notable water-purifying effects. Through their own unique growth characteristics and functions, they provide effective purification and filtration for water bodies. In practical application, we can choose suitable plant species for planting according to specific circumstances, so as to improve water quality and protect aquatic ecosystems. At the same time, we also need to strengthen management and maintenance to ensure that these aquatic plants can continue to play their role in purifying water.
