Rotala Manipurensis
Plant Profile
Rotala Manipurensis is a rare aquatic stem plant native to Southeast Asia and northeastern India. Its leaves narrow into fine, feather-like whorls that blush orange, salmon, and bright pink when grown under high-tech aquarium conditions. Once established, it grows quickly and fills in with dense, layered stems, working well as a midground or background species that adds structural depth, soft movement, and warm color contrast against greener aquascape plants. It's a good pick for aquascapers looking to break up an all-green layout without reaching for the more common red Rotala varieties.
*Form Notice: Photos display this plant in both its emersed (above-water) and submerged forms. Depending on nursery availability and seasonality, you may receive this plant in either form. Learn more about what to expect by reading our guide on Emersed vs. Submerged-Grown Aquatic Plants.
Key Features & Benefits
- Narrow, fine-textured foliage shifts into striking orange and pink tones under high-intensity lighting and tuned fertilization.
- Fast vertical growth habit quickly forms dense, colorful background bushes through routine pruning and stem top replanting.
Care & Planting Instructions
- Remove lead weight and remove cotton wrap (or foam) surrounding the base, then strip the lower inch of foliage so bare stems anchor cleanly into soil without rotting. *Rotala Manipurensis has fragile leaves, so handle stems with care during preparation.
- Use fine-tip pinsettes to push individual stems 1 to 2 inches into substrate, spacing them slightly apart so light reaches lower foliage.
- Provide high-intensity lighting, pressurized CO2 injection, and nutrient-rich aquarium soil; adding liquid iron supplementation is key to developing vivid orange and pink coloration. See our guide to growing red aquarium plants.
- Maintain stable water parameters (72–84°F) and avoid sudden environmental shifts to prevent leaf melt or stem rotting.
- Trim stem tops with straight scissors once they reach the water surface to keep growth compact, and replant trimmings directly into soil to propagate. Read our trimming & propagation guide for details.

Frequently Asked Questions
1. Why are the lower leaves falling off my stem plants?
Lower leaf loss (leggy stems) usually occurs when lighting cannot reach the bottom of the plant due to overcrowding or shading from larger plants. Spacing individual stems slightly apart during initial planting and maintaining strong light penetration will keep lower leaves healthy.
2. How do I get my Rotala Manipurensis to display bright orange and pink colors?
To bring out its signature orange and pink leaf tones, provide high light intensity, pressurized CO2 injection, quality aquarium soil, and regular iron dosing. Lower light levels will cause the plant to remain predominantly olive-green.
3. How do I transition Rotala Manipurensis from emersed to submerged growth?
When transitioning from emersed to submerged growth, plant bare stems securely into rich substrate under high lighting and keep water parameters stable. As new growth adapts, the plant will shed its rounded land leaves and sprout narrow, delicate orange-pink underwater foliage. Once new shoots develop, trim away old lower growth to encourage dense branching.
