Echinodorus grisebachii 'Tropica', also known as Echinodorus parviflorus 'Tropica', is a small, distinctive sword plant that was discovered in the Tropica nursery in Denmark during the 1980s. This plant is well-suited for the foreground or middle ground of aquariums due to its compact size, which typically ranges from 5 to 10 cm in height. It forms a spreading rosette of medium to dark green, slightly bullate leaves that are narrow and obovate, resembling Samolus valerandi.
