  • Flower: None
  • Supplied loose: one portion contains ten strands.

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 is slower growing than most oxygenators, and will thrive even in shady ponds (it often grows underneath floating leaves like those of waterlilies). During the winter, it dies back to short, dense, pieces (winter buds - see fourth picture), which will sink to the bottom and rise again in spring to early summer. Just place the plant straight in the water. 

Hornwort is quite a late plant, since it is a floating plant and remains at the bottom of the pond until the water begins to really warm up. (Unless it is grown artificially under glass). If you are waiting for hornwort as part of your order, please be aware that it is likely to be late spring before it can be sent.  

If designing a planting scheme, we recommend approximately 1 bunch of Ceratophyllum per two square feet of water surface.
