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. The colour develops well when the light intensity is high and there are sufficient micronutrients in the aquarium.
