The cultivar Echinodorus ‘Barthii’ is a decorative and beautiful solitary plant for large aquariums. It becomes 25-50 cm tall and the whole rosette 20-30 cm wide. The leaves change colour from dark-red in the youngest leaves to dark-green in the oldest and also depending on how rich on iron is the susbtrate.. The colour develops well when the light intensity is high and there are sufficient iron micronutrients in the aquarium. A nutritious bottom helps it growth quite big. This plant takes a lot of light from plants underneath, so it must be pruned occasionally.
