Echinodorus horemanii is a stately sword plant from South America, producing broad, dark olive-green leaves that can reach 40–50 cm in length. It forms a dense, spreading rosette suited to larger aquariums where it can develop to its full potential.
This species is uncomplicated to keep, tolerating a wide range of water conditions from soft and slightly acidic to moderately hard. It grows well under medium lighting without the need for CO2 injection, drawing nutrients primarily from a rich substrate.
Supplied as an established potted plant, Echinodorus horemanii makes a commanding background specimen in aquariums of 200 litres or more. Its broad leaves provide natural cover for fish and spawning sites for cichlids and other bottom-dwelling species.
