Get Rotala 'H'ra'
Propagation
Top the stems and replant; repeated trimming builds the dense, mounded bushes the cultivar is known for.
Frequently asked questions
How do I get the deepest red out of Rotala H'ra?
Strong light is the foundation; from there, keeping nitrates lean (roughly 5–10 ppm) while maintaining phosphate, potassium, and iron pushes the tops from orange toward true red. In nutrient-rich or dimly lit tanks it grows fine but stays orange-green.
Is Rotala H'ra harder to grow than regular Rotala rotundifolia?
No — the care is essentially identical and it survives low-tech tanks the same way, just without the color payoff. The only real difference is that H'ra needs the high-light, lean-nitrate treatment to show why you bought it.
