A classic aquarium stem plant. The Rotala rotundifolia originated from Southeast Asia and the name refers to the shape of the leaves but only when it's above the water line. Once submerged, the leaves become narrow and exhibit beautiful red tones and when they sway in the current, look quite delightful.
Relatively undemanding plant, the brighter the light, the more red colours this plant displays. It readily forms side shoots and can become quite bushy. Bear in mind, this can cause make it harder for light to penetrate the lower leaves and as a result, regular trimming is recommended.
