Ceratophyllum demersum (Hornwort) – The Ultimate Oxygenating Plant for Healthy, Vibrant Pond Water

Hornwort (Ceratophyllum demersum) is one of the most popular oxygenating plants in the UK, making it a must-have for anyone looking to enhance their pond’s water quality.

Hornwort thrives effortlessly with minimal maintenance—simply weight it down in your desired location, and it will quickly get to work oxygenating your pond.
