This undemanding yet interesting stem plant is one of the easiest colored red plants to grow. Its ability to handle virtually any temperature (18-28C), pH (5-8), or hardness in the typical planted aquarium makes it suitable for many applications. While CO2 and high light are not requirements for this cultivar to grow, they are essential in bringing out the nice red to pink color for which this plant is famous. Iron is another factor in intense coloration�without enough Fe in the water column, this plant will become pale or, in extreme deficiencies, even white.
This plant, like many of the faster growing stem plants, can develop a tendency for horizontal growth and creep along the substrate. This is often caused by higher light levels and a plant's natural tendency to 'take over' as much space as it can before it changes to producing more vertical growth. Ways to avoid this are to crowd the plant or to increase phosphate (PO4) levels. Propagating and pruning this plant is very simple. Simply top and replant. This species produces many side shoots when pruned like a hedge, creating an attractive, manicured bush.
H. polysperma 'Sunset' has great potential as a red stem plant. Its interesting leaf texture and color make it a great addition to the mid- or background. The leaf size, up to 2 inches, is not overly large, making it suitable for all but the smallest aquaria.
