Alternanthera lilacina is one of the nicest red background or midground plants. It adds a striking contrast to green plants.
To keep the best colour
- High light: 8–10 hours daily.
- CO₂: Highly recommended
- Fertilizer: Regular NPK and trace elements, especially iron.
- Substrate: Nutrient-rich aquasoil or root tabs.
- Pruning: Trim the tops when they reach your desired height and replant the cuttings to create a fuller bush.
