Hornwort is a genus of aquatic plants that belong to the Ceratophyllaceae family. It is an evergreen, perennial plant that can grow up to 2 meters tall. It has dark green, needle-like leaves that are found in whorls along the stem. The stems are oppositely arranged and can be straight or curved. Hornwort can be found in a wide range of habitats from shallow to deep water, and is often used as a natural filter in aquariums. It is also used as an oxygenating plant for fish and aquatic invertebrates.

Does Hornwort Root?

The short answer is yes, hornwort does root. It is not uncommon to find hornwort plants with roots growing down into the substrate of an aquarium. The roots of hornwort are typically thin, white, and have a stringy appearance. They are not as strong as the roots of other aquatic plants, but they do provide some stability for the plant.

The Benefits of Hornwort Rooting

Having a rooted hornwort in an aquarium has several benefits. First, the roots help to anchor the plant, which makes it less likely to float away or be pulled out of the substrate by water currents. This is especially important in aquariums with high flow rates. The roots also help to provide additional nutrients to the plant from the substrate, which can help it to grow and thrive. Lastly, rooted hornwort can help to reduce algae growth, as the plant will absorb some of the nutrients that algae needs to survive.

How to Help Hornwort Root

If you want to encourage your hornwort to root, there are a few things you can do. First, make sure that the substrate in your aquarium is nutrient-rich. Hornwort can absorb some of the nutrients from the substrate, so it is important to make sure that the substrate is of good quality. You can also add root tabs to the substrate to provide additional nutrients for the plant. Additionally, make sure that the hornwort is placed in an area of the aquarium where it will receive plenty of light. This will help the plant to grow and thrive.


In conclusion, hornwort does root and this can be beneficial in an aquarium. The roots provide stability for the plant and help to absorb nutrients from the substrate. Additionally, rooted hornwort can help to reduce algae growth. To encourage rooting, make sure that the substrate is nutrient-rich and provide plenty of light for the plant. With the right conditions, your hornwort should root and provide a beautiful addition to your aquarium.
