Plants are one of the most important parts of a pond ecosystem. They remove excess nutrients, offer protection for wildlife and help create a natural, balanced environment. Here is a guide to the main types of pond plants and some of the best species to consider.


About aquatic plants

Aquatic plants, also known as macrophytes, grow in or near water. They may float, emerge above the surface or grow fully submerged. They differ from algae because they evolved from land plants that adapted to life underwater.


Choosing the right plants

Plants add structure, colour, scent and shade. They oxygenate the water, support wildlife and help control algae. There are four main categories of pond plants, each with a specific role.


Submerged plants

Grow below the surface and act as natural oxygenators and filters.


Floating plants

Float freely or sit on the surface, keeping water cool and shaded to help prevent algae.


Marginal plants

Grow at the water’s edge and soften the boundary between land and water.


Moisture-loving and bog plants

Grow in wet or boggy soil and offer excellent cover for wildlife.



If you’re unsure which plants to choose, we’re always here to advise.
