Giant Red Rotala
Rotala macrandra
Family: Lythraceae
Rotala Macrandra is widely regarded as one of the most beautiful red plants in the hobby, with broad, crinkled leaves that turn vibrant crimson under optimal conditions. It is also one of the most demanding stem plants, requiring very high light, injected CO2, intensive macro and micro nutrient dosing, and soft acidic water — any deficiency quickly manifests as yellowing or failure to colour up. Rewarding for experienced planted tank keepers.
