Echinodorus 'Red Diamond' appeared as a culture in the Ukraine, and is probably a cross between Echinodorus horemanni 'Red' and Echinodorus ‘Barthii’. The resultant hybrid is an attractive plant with ruby-red sword-shaped leaves, 15-25 cm long.
 
Unlike many of the other Echinodorus-species, Echinodorus 'Red Diamond' remains moderate in size (20-30 cm wide roset), so it is extremely well suited as a solitary plant, even in small aquariums.
 
Increasing the nutrients in the substrate results in more abundant growth, while favourable light conditions promote the formation of the ruby-red leaves.
