Oxygen Plants

Hornleaf

Hornleaf (Ceratophyllum Demersum) is a native aquatic plant suitable for the pond and an aquarium. It grows quickly, adds instant oxygen to the water, keeps it clear and requires little care. Ideal for healthy oxygen levels.

Simon van der Velde

For oxygen plants, I recommend a minimum of 10 to 12 individual plants per m³ (1000 liters of water) and 2 baskets of 8 plants per m². The amount needed depends on how quickly you want the pond to balance and your visual requirements.

Frequently asked questions about Ceratophyllum demersum

Pond Advice

Yes, there are two types: coarse and fine hornwort. Functionally they are identical, but coarse hornleaf has broader and coarser stems compared to fine hornleaf.

You can simply place a stem of hornwort in the water, where it will float and continue to grow. You can also plant it at the bottom of the pond to a depth of 120 cm. Hornleaf grows quickly, at up to 10 cm per day, and a stem can grow up to 3 meters long.

It is recommended to place a minimum of 6 stems per square meter and a maximum of 12 stems per square meter. This ensures an optimal balance of oxygen plants in the pond.

Hornleaf is available from Van der Velde Waterplants. 6 bunches cost €19.95 and 12 bunches €29.95. All plants come directly from their nursery, are well packaged, and you get a 100% growth and flowering guarantee.

Don't worry if you notice that the hornwort in your pond is a brown or reddish color. This is actually quite normal and a good sign of natural cultivation. Interestingly enough, the original color of hornwort tends toward brown or red. This natural coloration is more pronounced because you choose a natural growing method, without artificial light or chemicals. As summer approaches and more natural sunlight becomes available, you will see how the hornwort gradually changes to a more vibrant green. This beautiful process shows the true beauty of natural growth and adaptation to the environment. By choosing 100% organic cultivation, you are embracing the natural cycle of plant life. Seeing this color change in the hornwort confirms the power and value of your commitment to natural growing methods.

Hornleaf Ceratophyllum demersum: the best oxygen plant for the pond

Hornleaf (Ceratophyllum demersum ) is a dark green aquatic plant in the Hornleaf family often found in various waters. This plant, with its floating nature, can reach a length of 60 to 90 cm. A striking feature of the hornleaf are the side stems that sprout from the main stem, from which wreath-shaped, forked leaves grow. These threadlike, line-shaped leaves are rather stiff, and their forks have sharply serrated edges.

What makes the flowering process of this plant unique is that within the same plant, in the leaf axils, both male and female flowers can occur. The flowers are characterized by a 10- to 12-slip flower cover. Within this flower cover are about 20 stamens with short anthers in the male flowers, or an erect ovary with a style and stigma in the female flowers. The process of fertilization takes place under water, with pollen reaching the stigmas through the water. From this fertilization arises achenes with characteristic thorns.

The spread of hornwort in different waters can occur in a variety of ways. Wave action can cause pieces of the plant to break off and end up elsewhere, and waterfowl can also contribute to the spread by carrying pieces of the plant on their legs.

A special characteristic of hornwort is that it prepares itself in winter for the colder months. The plants form densely foliated shoots that sink to the bottom to overwinter. When spring arrives again, these sprouts grow into new, full-sized plants. As a result, we are dealing with a long-lived, perennial plant species.
