A British native species which is an attractive plant and a very convenient oxygenator. It has no true roots and therefore does not need to be potted, but grows floating freely in the water (although it appreciates a layer of silt on the bottom of the pond and will often push down into this). This also makes it easy to remove if needed. Hornwort will thrive even in shady ponds. During the winter, it dies back to short, dense, pieces (winter buds - see third picture above), which will sink to the bottom and rise again in spring.
Just place the plant straight in the water.
If designing a planting scheme, we recommend approximately 1 bunch of Ceratophyllum per square foot of water surface.
