Je cherche des plantes qui filtrent l'eau

I'm looking for plants that filter water

Plants that filter water? You've probably heard of it before, but do you already have it? Today, we have concocted a small list of plants known for their purifying power.

In other words, these plants assimilate the excess organic matter present in the water and participate in the improvement of the nitrogen cycle. We are talking in particular about elements such as nitrates, phosphates, etc.

Which plants to choose to filter pond water?

Phyto-purification is therefore the natural technique allowing the filtering of water thanks to certain plants. In other words, it is a process of sanitation of aquatic basins and this, through vegetable plants.

This method is also called helophyte filter or filter swamp. It therefore consists of using these plants to develop purifying bacteria in the water. These will be responsible for purifying the water in a pond, removing pollutants and other substances of all kinds.

Such an operation is made possible thanks to the root of helophyte plants. Indeed, they favor the presence of nitrogens and phosphates in the water. This concentration of minerals constitutes in particular an obstacle to the development of algae.

In this way, there is generally a better growth of purifying plants, which make the water clear. In this article, we will try to go around the plants that are known to filter the water in a pond.

The Water Bur-reed

The scientific name for the Water Bur-reed is Sparganium erectum . This herbaceous plant is also called branched bur-reed. It is particularly known to grow on the banks or in deep waters.

Recently, the water bur-reed has been placed in the Typhaceae family. Among other particularities, the water bur-reed has depolluting virtues, unanimously recognized.

The marsh iris

This depolluting plant is known by several names: yellow iris , Flambe d'eau, false sweet flag iris, etc. From its scientific name Iris pseudacorus . This plant is found in the order Asparagales.

The marsh iris can be recognized by its green foliage and its yellow-tinted flowers. To plant it, it is recommended to plant it in September. However, it will be necessary to wait until the following March to see its first leaves emerge from the ground.

The marsh iris is a very popular plant, especially considering its strong ability to serve as a depolluting plant.

The common reed

The common reed is one of the most used plants for phytopurification. From its scientific name Phragmites australis , this plant is known by many nicknames: Broom reed, Sagne, Phragmites, etc.

Common reed is a member of the Poacea family, in the Arundinoideae subfamily. It is generally found near bodies of water, in ponds or marshes.

sweet flag

Like the other plants on this list, sweet flag is also used for depolluting ponds. From its scientific name acorus calamus , it is a plant native to Asia. It is also called the scented rush.

It is recommended to plant it in the spring, although it will not flower until the following summer. The sweet flag is more often considered for its decorative effects, nevertheless it has a strong capacity for depolluting basins and ponds.

Narrow-leaved cattail

From its scientific name Typha angustifolia , this plant has green leaves as well as distinctly brown lovers. The narrow-leaved cattail is also known as the cattail, in Canada.

This plant of the Typhaceae family is mainly used for the elimination of zinc, in addition to these anti-polluting faculties.

acute bulrush

Acute bulrush is known by many other names: chair rush, cooper rush, lake bulrush or pond bulrush. It is a plant classified in the Cyperaceae family, whose scientific name is Schoenoplectus lacustris .

Acute bulrush is often used in erosion control and phytopurification | Photo: Wikipedia

It often happens to be used in the fight against erosion, in particular within the framework of the protection of the banks of basins. Nevertheless, it is much more effective in phytopurification. And for good reason, acute bulrush has a high potential for the absorption of heavy metals and phenols.

The weight of water

Pesse vulgaris refers to this same anti-polluting plant called “Oxygenating Horsetail”. It is also known by its scientific name: Hippuris vulgaris , in the Plantaginaceae family. It can just as easily be found in Europe, Asia or North America.

A submerged and invasive plant, the pesse d'eau is used to clean up ponds. Among other peculiarities, it is known to produce oxygen in surprising abundance.

Water Milfoil

From its scientific name, Myriophyllum aquaticum , the water milfoil is part of the Haloragaceae family. It is also called the Brazilian Milfoil. It is found today on all continents, although it comes from South America.

Water milfoil is used in phytopurification in the same way as other plants. If it produces enough oxygen, it will still be necessary to take care of the speed of propagation. And for good reason, it is a very invasive plant.

The swimming pondweed

The pondweed, or Potamogeton natans , is a member of the Potamogetonaceae family. This plant is found in the northern hemisphere.

It is a plant that grows in a temperate environment. It is particularly appreciated for its strong anti-polluting capacity.

Canadian waterweed

Originally from North America, waterweed from Canada is also nicknamed the water plague. It is a plant classified in the family of Hydrocharitaceae.

Waterweed is a very oxygenating plant. This is also why it is very popular in phytopurification.

Pontederie

Pontederia has the scientific name Pontederia cordata . It is an aquatic plant, generally used for its anti-pollutant functions.

Planted along the edge of ponds, it plays a purifying role. It can also be planted in deep water.

The Marsh People

The marsh marigold has the scientific name Caltha palustris , and is part of the Ranunculaceae family. It is known by other names, such as Caltha des Marais or Marigold.

If this plant is cited in the category of oxygenating plants, it is because of its high potential in oxygenation. Indeed, it distinguishes itself by collecting pollutants from the soil, then moving them up into its leaves.

Common loosestrife

Common Loosestrife is a plant classified in the Lytraceae family. It is known by its scientific name: Lythrum salicaria .

Its filtering quality places it at the forefront of plants used in phytopurification.

mentha aquatica

Water mint, whose scientific name is Mentha aquatica , is very popular in phytopurification. And this is no coincidence: this plant has a good filtering quality.

It is therefore no surprise that it is widely used in the context of the natural sanitation of basins.

Equisetum hyemale

Equisetum hyemale is also called Winter Horsetail, Himalayan Horsetail or Giant Horsetail.

It is an aquatic plant that has been successfully tested for depolluting ponds. Its effectiveness is total.

Conclusion

In summary, we therefore have a list of fifteen plants that are well suited to filtering pond water. At the same time as planting them and monitoring their propagation, do not forget to regularly test your water. This will allow in particular to keep an eye on the balance of the pelvis, and to correct it if necessary.

J’ai besoin. De plantes pour mon assainissement d’eau grise domestiques
J’ai besoin. De conseils et suivis

Michelle Planell - April 27, 2023

Bonjour, je suis une personne agée ! je voudrais un bassin avec de la faune et de la flore “heureuse” dans mon jardin – je n’y connais pas grand chose ; sinon, que pour avoir une eau “saine” il faut qu’il y ait des plantes, oxygénantes, filtrantes, dépoluantes, … OK!
j’ai un petit bassin 120×40×50h, je ne veux pas risquer d’être envahie par une végétation trop importante, j’aime : iris jaune, papyrus, puces d’eau, jacynthes d’eau, menthe, ceratophylum, pontederie, renoncules, !!! il en manque ? il y en a trop ? un conseil serait le bienvenu, parce que je voudrais avoir une eau claire sans trop me prendre la tête !
Ensuite de la faune … bouteille d’encre noire … ! non pas de sépia !!!! des poissons rouges et quelques escargots et moules d’eau … toujours pour avoir un équilibre eau/faune/flore, et que cela reste un agrément … Help! merci pour votre aide,
Michelle
