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. This also makes it easy to remove if needed. Hornwort will thrive even in shady ponds. Just place the plant straight in the water. During the winter, it dies back to short, dense, pieces (winter buds - see fourth picture above), which will sink to the bottom and rise again in spring.
