Complete Cultivation & Spawning Guide

Follow our detailed scientific water parameters and care guides to keep your Limnophila Aromatica thriving.

pH: 6.0 - 7.5, GH: 3 - 15 dGH. Highly adaptable to both soft and hard water setups.

Moderate. Beneficial for lush growth and rich red leaf development, though it can grow steadily in low-tech setups.

Moderate to high. High light intensity keeps the leaves compact and deepens the gorgeous reddish-purple marbling.

Propagate by cutting the top healthy stems and replanting. Cut mid-stems to force bushy lateral branching.

Requires heavy iron and micro-nutrient dosing to develop and maintain its iconic brilliant red color.

Requires rich aquasoil. Provide slow-release root tabs to feed its vertical root network.

Optimal temperature is 20°C to 28°C (68°F - 82.4°F). Sensitive to sudden cold water shocks during maintenance.

Requires steady water circulation. Good current prevents organic waste and algae spores from landing on broad leaves.

Its tough texture and bitter taste make it highly resistant to plant-eating fish. Safe for community setups.

Slow growth makes it susceptible to hair algae. Keep water clean and employ Amano shrimps or Nerite snails.

Best placed in the background. Space individual stems 1 to 2 inches apart to allow light penetration.

Common Diseases & Treatment

Stem Base Rot

Symptoms: The bottom of the stem turns black, soft, and decays in the substrate.

Action: Caused by poor oxygen levels in compacted soil or insufficient water movement. Thin out the stems to improve flow.

Loss of Purple Color

Symptoms: The beautiful purple undersides of the leaves fade to a dull pale green.

Action: A sign of iron deficiency or low lighting. Increase iron dosing and light intensity immediately.

Frequently Asked Questions

Does Limnophila Aromatica really smell?

Yes! When crushed, the leaves release a wonderful, strong aroma of herbal citrus and cumin. It is actually used as a culinary herb in Vietnamese cuisine (Rice Paddy Herb).

How do I propagate it?

Cut the stem below a leaf node and replant the top section in the substrate. The remaining bottom stem will sprout two new shoots.

What light levels does it need?

It prefers moderate to high light. Under low light, the stems will stretch, leaves will be spaced further apart, and the purple color will fade.

Can it grow emersed?

Yes! In wet bog conditions, it grows emersed with thicker, hairy green leaves and produces beautiful tubular purple flowers.
