Rotala Macrandra (Red)
The “Giant Red” Rotala is highly demanding, needing high-intensity lighting, no shade, and high Co2 injection. To prevent shading, the individual stems must be planted far enough apart for the lower leaves to get enough light. One established the plant grows: up to 4” per week, in optimal conditions. To keep the distinctive red color, ensure that the Rotala has plenty of phosphates (1.5 – 2.0 ppm) and not too much nitrate. (10ppm or less.) An incorrect amount of either of these nutrients will lead to stunted growth or discolored leaves.
Its medium-sized, red leaves grow from a stem which can reach a height of about 1’.
