Rotala Vietnam H'ra (Rotala rotundifolia "Vietnam H'ra") is a very prolific, versatile stem plant that is one of the easier "red leaf" plants to keep. This particular variety is a geographic variant that is known for its red stems, red, orange, and green leaves, and creeping growth.
 
It is tolerant of a wide range of water parameters and is an easy plant to grow; it does well even in aquariums without carbon dioxide injection after a period of adjustment. However, having sufficient light and CO2 allows it to grow with better density, and better coloration.
