Rotala rotundifolia ‘Hi Red’ (HRA) [Hybrid pot] is a variety discovered in a Vietnamese province. This plant is especially popular in the planted aquarium hobby due to its remarkably deep pink narrow pointed leaves when grown in submerged settings. The growth habit under light conditions is nearly identical to R. rotundifolia ‘Green,’ as it can grow downwards after reaching a certain height. Increasing the amount of NITROGEN in the water column may cause the leaves to turn pink. However, if NITRATE-containing fertiliser capsules are added to the substrate, good fertilisation with CO2 addition can cause the plant to produce pink-colored leaves continuously. This plant can survive in low-CO2 environments, but it thrives in high-CO2 environments.
