Elodea also knew as waterweeds, in North America it is also known as Anacharis. It is an aquatic plant. It belongs to the family of tape-grasses. Hydrocharitaceae is one of the most vastly used aquarium vegetation in overall the America.

It lives in freshwater. There are six different species of this aquatic that originated in North America and South America.

Elodea has Dark-green leaves in dense whorls of three to four that become more crowded toward the top. It Grows in a variety of pond but prefers to grow in fine sediments at the bottom of cool, spring-fed ponds.


Hydrocharitaceae is one of the few pond plants that can remain green all winter. If you cut it through it can reproduce primarily through stem fragments.

History of Elodea

Following is the history of the Elodea plant.


Elodea is a 6 species genus of aquatic plant that is also known as waterweeds. This genus was described in 1803. Elodea plant is native to South and North America and it is also widely used as a aquarium vegetation. This plant lives in the freshwater.


This aquatic plant is usually found in North America (Native Plant). And also found in overall the world. In overall the Europe, Hydrocharitaceae is considered as a weed due to its ability to grow faster in many diverse habitats and conditions.

Distinctive Features

The distinct features of the Elodea plant are explained in detail below :


It is very beneficial for the echo system in water. If you have a fish pond in your home this plant is very beneficial for the ecosystem. Hydrocharitaceae is a good source of food for the creature inside the water like small insects.

Brazilian Elodea

That is a good source of food for fishes? These plants also provide a hiding place to the fishes for other predators in the water. People use the elodea plant as a purpose of decoration.


Excessive growth of Hydrocharitaceae is a big problem. Usually, this is happening due to the fertilizers we use for the corps and to grow other plants. When this fertilizer is mix with the pond water or enters into the lakes.

This causes them to grow more rapidly. Too much elodea consumes more oxygen from water. That cause the deficiency of oxygen in the water that leads to potentially kill them.

It has the ability to grow rapidly and can easily occupy the new areas. Not only that it also prevents other species of plants to grow up.

Elodea plant description

Elodea plant stems are the long and slender shape. These multi-branched stems can reach up to more than 10 feet in length. Elodea attaches its roots to the substrate, they are not free-floating plants.

The leaves of these plants have blade-shape with fine-toothed edges and their leaves are of bright and dark green color.

Elodea canadensis

Hydrocharitaceae is dioecious in nature. Each plant produces either a female of male flowers. Elodea flowers are of white color, they are born above the surface of the water.

Their petals are layered with wax that prevents the flowers from sinking. The fruit of elodea is of cylindrical shape, filled with small seed.

The more common way of production is via seed and via fragmentation of the stems. There is a biological weapon named as “Grass Carp” which is used for the elimination of elodea from the ponds.

Elodea plant is used for the demonstration of the photosynthesis process in the class. Because when this plant is mixed with bromothymol blue which is a chemical compound when elodea absorbs the carbon dioxide, the blue liquid changes its color.


The lifespan of this aquatic plant is not very long. It can only live up to 2 years.
Cultivation Details

  • It is a floating, submerged plant.
  • It grows well in slow-moving water and also in small ponds.
  • It can grow rapidly when able to root into the mud.
  • This species of water plant was introduced to British waterways in the mid-nineteenth century.
  • Later on, they spread rapidly to become a great peat and blocking many waterways.
  • The most species of this plant grown in Britain are a female clone.

Edible Uses

  • This plant does not have any edible use for Human But a good source of food for fish and other small animal species.
  • Elodea is a Genus of 6 species of Sea plants, that is widely used as aquarium vegetation.
  • This plan is a good source of food for small insects in water and also provide shelter for fish of small species.

Medicinal Uses

Up till now, there is no medical use of elodea is found, however, Scientist does proper research in different labs, on how light wavelength affect the process of photosynthesis in an aquarium in elodea plant.
