Rotala Macrandra is a dramatic back or mid-ground stem plant with red leaves that make a striking contrast to the usual green foliage. This plant can be difficult to grow since it requires very higher levels of light and nutrients. Without sufficient lighting, the plant’s bottom leaves will shrivel and fall off. In its emersed state, leaves will grow prostrate and have a green color. The submerged version will grow upright and have a deep red color. Given the proper growing conditions, Rotala Macrandra grows quickly.

They will be their brightest red when nitrates are low, but phosphate and micronutrients are high. If the plant’s leaves can appear pale red or have white markings if it does not have sufficient iron levels. Rotala Macrandra will grow best with CO2 levels from 15-25ppm.
