This is a unique stem plant with saw-toothed edges on the leaves.  Colors can range from a bright solid red to a lighter golden green coloration depending on lighting and nutrients.  The leaves turn more red when dosing iron supplements in your tank.   
This plant acts as a great background coverage, especially in a Dutch style aquascape where the unique leaves can add a great contrast to other plants.  
Propagation is simple and straightforward like other stem plants.  Simply cut along the stem and replant the cuttings.
