Echinodorus palaefolius, or the Mexican Sword Plant is a tall and delicate plant. It has long thin leaf-stalks and spear shaped leaf blades. Its flowers are white and has only three petals. They can be found in Brazil and Mexico.

This beautiful large aquarium plant is a case for the background in the aquarium. It becomes quite expansive and needs a bit of space. It is particularly beautiful in open aquariums, where the inflorescences can then grow above the surface of the water.
