Plant Maintenance
Similar to Rotala wallichii, the "Long Leaf" variety thrives in soft water with bright lighting, CO2 supplementation, and consistent fertilisation with both macro and micronutrients. The most intense reddish coloration in the leaves is achieved under strong lighting. This plant grows quickly under optimal conditions and, like other stem plants, can be easily propagated by cuttings.
Emersed Growth
This plant exhibits differences in its submerged form, such as a darker, more reddish hue and an upright growth habit, which sets it apart from R. sp. "Nanjenshan." The shoots typically reach up to 5 cm in width. When grown emersed, the leaves become coarser, broader, and light green.
