Hornwort (Ceratophyllum Demersum)

Hornwort, also known as Ceratophyllum Demersum, is found worldwide. It is a well-known plant in the hobby. It grows long stems with needle-like and stiff leaves or, in common parlance, the "horns" from where it takes its common name. Hornwort can be used as a floating plant or as an upright stem plant. It does not have roots but when planted, Hornwort produces rhizomes that allow it to attach to the gravel. This plant is a fast grower and many hobbyists use it in fry tanks to provide hiding places for young fish. Because of its fast growth, Hornwort is great for planted aquariums as it will quickly absorb extra nutrients from the water column, preventing algal blooms.

Hornwort can flower and produce seeds. However, the flowers and seeds are small and hardly noticeable. The best and easiest way to propagate hornwort is to snip the stems apart. The separated pieces will just continue growing, creating new plants.
