Elatine hydropiper, commonly known as Waterwort or Marshwort, is a small aquatic herbaceous plant that belongs to the family Elatinaceae. It is a delicate plant with thin stems and small leaves that grow in clusters. The species has a unique growth habit, with its stems often lying flat across the surface of the water.

Distribution and Habitat

Elatine hydropiper is native to Europe, Northern Africa, and Western Asia. It is primarily found in freshwater habitats, such as marshes, slow-moving streams, and ponds. The plant thrives in shallow water with muddy or sandy substrates. It is well adapted to the aquatic environment and can tolerate periods of flooding and drought.


The species Elatine hydropiper belongs to the genus Elatine, which comprises several other aquatic plants. The genus Elatine falls under the family Elatinaceae, which consists of small annual or perennial herbs. Elatinaceae is a small family of flowering plants, with only a few genera and around 35 recognized species.

Physical Characteristics


Elatine hydropiper is a small plant that typically grows to a height of 5-20 centimeters. The stems are thin and delicate, ranging in length from 5-30 centimeters. The plant forms dense mats on the water’s surface, providing important shelter and habitat for various aquatic organisms.


The leaves of Elatine hydropiper are small and narrow, measuring around 1-2 centimeters long and 1-3 millimeters wide. They are arranged oppositely along the stems and have a smooth, lanceolate shape. The leaves are bright green in color and have a glossy appearance.

The flowers of Elatine hydropiper are tiny, measuring only about 2 millimeters in diameter. They are white, pale pink, or purple in color and have five petals. The plant produces solitary flowers that are borne on short stalks emerging from the leaf axils.


After successful pollination, Elatine hydropiper develops small and round fruits known as capsules. These capsules contain numerous tiny seeds that are dispersed through water or by animals. The seeds are an essential means of reproduction and further spread of the species.

Growing Conditions


Elatine hydropiper thrives in full sunlight or partial shade. Adequate light is crucial for the plant’s photosynthetic activity, allowing it to produce food and grow efficiently. In shaded areas, the growth rate may be slower, and the plant may stretch to reach more sunlight.


The ideal temperature range for Elatine hydropiper is between 18-24 degrees Celsius. It prefers mild to warm conditions to flourish. Extreme temperatures, especially freezing ones, can be detrimental to the plant’s survival.


As an aquatic plant, Elatine hydropiper requires a consistently moist environment. It can grow under both submerged and partially submerged conditions. However, extended periods of flooding or drought can negatively affect its growth and overall health. Adequate water quality is also important, as the plant is sensitive to pollutants.


Elatine hydropiper is adaptable to various types of soil, including sandy and muddy substrates. It does well in moist, fertile soils with good organic content. The plant can also grow in aquatic habitats with clay or loamy soils.

Cultivation Techniques


Elatine hydropiper can be propagated through both seeds and vegetative means. Seeds can be sown in a suitable aquatic environment, ensuring they are submerged or kept moist until germination. Vegetative propagation can be done by taking stem cuttings and planting them in a suitable substrate.


To establish Elatine hydropiper in an aquarium or outdoor pond, it is essential to recreate its ideal growing conditions. This involves providing the correct lighting, temperature, water quality, and suitable substrate. The plant can be gently placed or anchored into the substrate to ensure stability.

Regular maintenance is necessary to ensure the successful growth of Elatine hydropiper. This includes monitoring water quality parameters such as pH, temperature, and nutrient levels. The removal of any debris or dead plant material is also important to prevent water pollution and maintain the health of the plant.

Pests and Diseases

Elatine hydropiper is relatively resistant to pests and diseases. However, it may occasionally face challenges such as algae growth, which can compete for nutrients and hamper its growth. Proper monitoring and maintenance can help prevent or manage such issues effectively.


Aquarium Plant

Elatine hydropiper is a popular choice for aquarium enthusiasts due to its delicate beauty and compact size. It is often used as a foreground or mid-ground plant in aquascaping, providing an attractive contrast to other aquatic elements. Its ability to create lush mats of green on the water’s surface makes it a desirable addition to the aquarium.

Medicinal Properties

In traditional medicine, Elatine hydropiper has been used for its diuretic and astringent properties. It has been employed for conditions related to the urinary system, such as urinary tract infections and kidney stones. However, it is important to note that further scientific research is needed to validate these traditional claims and explore its potential medical applications.

Conservation Status


Elatine hydropiper faces several threats to its survival and conservation. Habitat loss and degradation due to human activities such as drainage, water pollution, and invasive species introductions pose significant challenges for the species. Climate change and alterations in hydrological regimes also impact the plant’s habitat.

Conservation Efforts

Efforts are being made to conserve Elatine hydropiper and its habitat. These include the establishment of protected areas, restoration of degraded habitats, and the implementation of measures to reduce pollution and invasive species impacts. Public awareness and education campaigns are also crucial for promoting the importance of preserving this species and its aquatic ecosystems.
