The Red Rubin Sword plant (Echinodorus rubin) has green leaves when grown out of the water and when grown submerged develops red/brown leaves. It is known as a tall plant in the aquarium hobby, therefore better suited as a background plant that will add nice color other than green to your freshwater planted aquarium.
 
It is an easy plant to maintain, but grows tall in the aquarium. It requires a moderate level of light of 2 to 3 watts per gallon provided by a full spectrum light.
 
This species will propagate is by side shoots, rhizome division or a new plant will form at the end of one of its old leaves.  Just separate the new plant and re-plant. 
All plants are sensitive to copper, the Red Rubin Sword is no exception.  Be aware about the type of medication you are introducing to the aquarium, especially chemicals to control snails infestation, those are usually copper based and should not be added to a planted aquarium.
 
This plant will benefits from the additions of CO2 and fertilizers.
