Echinodorus "Red Diamond" appeared in Ukraine and is possibly a cross between Echinodorus horemanni "red" and Echinodorus "Barthii". The resulting hybrid is an attractive plant with sword-shaped ruby leaves, 15-25 cm long.

Unlike many other Echinodorus, Echinodorus "Red Diamond" remains moderate in size (20-30 cm wide), which makes it extremely suitable as a focal plant, even in small aquariums.

Increasing the nutrients in the substrate enhances growth, while favorable lighting conditions promote the formation of the ruby leaves.
