The Mexican Rotala originates in South America but can be found across tropical and subtropical regions of Central America, Africa, and Australia. Due to its wide distribution, the plant has been identified multiple times under different names, including Rotala pulsilla. This is a species that tends to thrive or die off completely. In order to thrive, it needs strong lighting and plenty of CO2, and macro and micronutrients. A low level of any of these factors will lead to blackening and stunted growth.

This long-leaved, stem plant grows quickly and lushly and is easy to propagate through cuttings. The stems are reddish, and with how tall the plant grows it makes a great choice for a background. With proper trimming, Rotala Mexicana can form a great hedge effect even in the midground of the aquarium.
