Hygrophila polysperma 'rouge'
Hygrophila polysperma ‘rouge’ is a slightly more demanding variant than related species. It grows moderately quickly, producing thick stems and large leaves which turn reddish pink with CO2 injection and a higher light intensity. If allowed to grow unhindered, this plant will produce a forest-like effect with relatively sparse stems, and thicker top growth. However, it can be trimmed more frequently for a bushier appearance more suited to a midground placement. To supplement this type of placement, stems can be clipped and the cuttings replanted in the substrate to promote thicker growth.
When iron deficient, H. polysperma ‘rouge’ may also grow pale or even white in color. To maintain its vibrant coloration, provide at least occasional nutrient supplementation.
