Genus: Echinodorus Family: Alismataceae
The plants from this genus are generally called sword plants or burhead, majority distributed in South America and a few in Northern counterpart. Majority of the species from Amazon basin, hence they are popularly called Amazon sword plants. Echinodorus means horned skin, a reference to beaked fruits of the plants. E. sp ‘Bleherae’ once had dominated in the aquarium trade due to its easiness in maintaining any aquarium tank. However, when late Takashi Amano floated the idea of Nature Aquariums through his masterpieces in early 2000 AD, hobbyists from across the world started using plants from other genera to create Nature Aquariums which more or less mimic the nature. Many species of this genus are bigger in size and not suitable for small tanks intended for Nature Aquariums. Echinodorus tennelus still popular as it can be used for carpet formation in the foreground settings in nano tanks.

Rather easy to maintain and can tolerate hard water. This species needs nutrient rich bottom to sustain its growth.
