These plants simply float on the surface of the pond. They are not planted, but are laid in the water. They produce roots to absorb nutrients from the water, rather than to attach themselves to anything. Surface floaters are an important element of a healthy pond. They filter the effects of sunlight on the water and remove large quantities of mineral salts.
This inhibits the growth of algae. Surface floaters multiply at speed and it is essential to remove plants from the pond regularly to stop the surface from becoming completely covered. We recommend always keeping two thirds of the water surface of your pond free of plant cover.
