What Are Some Of The Edible Aquatic Plants?


When you’re gardening, you’ve probably wondered, “What Are The Edible Aquatic Plants?” In this article, you’ll learn about several plants you can eat while growing in your pond.

Cattails, Nasturtium officinale, Cabomba, and more are just a few of the many choices.

In addition to these, you’ll also find a few plants you can’t resist: cattail rhizomes, arugula, and Cabomba.


Depending on where you live, cattails are a great addition to your pond.


Their rhizomes, which produce cotton-like down, are used for livestock feed. The byproducts of cattail growth are also used as mulch.

In the spring, cattail growth provides fair cattle forage. They can be pests, however, and can interfere with aquaculture operations and irrigation channels.

Moreover, their extensive growth can speed up eutrophication. Cattails have erect, cylindrical spikes with narrow leaves and a cigar-shaped flowerhead.

These spikes grow one to three meters high and produce a pair of staminate and female flowers. The staminate flowers fall over the pistillate flowers and fertilize them.

Later in the summer, a seed head forms, which contains about two hundred million seeds. The seeds disperse by the wind.

Cattail Rhizomes

If you’re looking for a new culinary addition to your pond, consider cattail rhizomes.

The leaves and rhizomes of the common cattail plant are also edible. In the spring, spikes and pollen form. The best times to harvest cattail are in the fall and in the spring.

Usually found growing near shorelines, cattails reproduce by seed or horizontal creeping stems. The seeds contain flavorful, sweet, and nutritious ingredients.

These edible aquatic plants are widely used as ornamental plants and can be incorporated into water gardens and landscapes.


The plant is often referred to as the “giant Cabomba,” but you can find many varieties available.


These plants are native to South America and thrive in freshwater with a pH of 6 to 7.5 and a temperature range of 22 to 28 degrees Celsius.

They also produce oxygen and absorb carbon dioxide, and are an important part of the aquatic ecosystem. Consequently, they are often grown for both their food value and their ornamental qualities.

The leaves of the Cabomba plant grow from the apical parts of the stem. The plant has an orbicular leaf shape. The stems are red and have fine longitudinal striations.

Cabomba is a facultative xenogamous plant that produces only one carpel in a follicle-like fruit. Its leaves and flowers are edible. Its seeds are oval and are available from May through September.

Nasturtium Officinale

Watercress, or Nasturtium officinale, is a perennial herb that is commonly known as “Watercress.”

It has been a problem in some areas because it can become invasive. Watercress has both male and female parts in its flowers. Pollination is carried by wind and water, as well as by bees, moths, flies, and butterflies.

Watercress spreads vegetatively by stolons that fall over. In addition, the stems of the watercress grow into roots. Animals, including wild deer, cows, muskrats, and snails, eat them.

Neptunia Oleracea

Known as a plant that grows in still water, Neptunia Olerace is an edible aquatic plant with a range of uses.

Although its native habitat is unknown, it is commonly found growing prostrate near the water edge or floating on water. The fruit and juice of the stem and roots are both edible and used medicinally.

A whole-plant extract was recently shown to have cytotoxic activity against neoplastic cell lines. The roots of N. Oleracea are used to make soups. It is cultivated in Vietnam and Thailand.

The edible part of the stem is harvested and eaten by the Manipur people, who remove the cotton-like substance that clings to it. It is regarded as a delicacy in two cuisines.

In addition to its nutrient-rich flavor, N. Oleracea is also high in protein and is used in the cuisine of the Manipur state.

Water Spinach

A common ingredient in Southeast Asian dishes, water spinach is a popular, nutritious vegetable. This plant’s wide, smooth stems trail along the bottom of ponds and streams and float above the water.

If you’re thinking of planting water spinach in your garden, keep reading. Water spinach has been used for thousands of years as a medicinal vegetable in southern Asia. It is native to Southeast Asia, and its first use was documented during the Chin Dynasty.
