Plant Profile
Rotala H'ra is a sought-after aquatic stem plant hailing from the Gia Lai province in the central highlands of Vietnam. A distinct geographic variant of Rotala rotundifolia, it's known for profuse, narrow, pointed foliage and a growth habit with a mind of its own: instead of growing politely upright like most stem plants, it overhangs, arches, and branches horizontally, doing its own thing. Under high-intensity lighting, pressurized CO2, and tuned fertilization, its foliage transforms into a breathtaking palette of fiery orange, salmon, and deep ruby-red, making it a stellar pick for sweeping midground bushes or dramatic background slopes.
Tissue Culture cups ensure your aquascape gets a super clean starting point. Lab‑grown and fully sterile, it arrives without pests, snails, duckweed, or any unwanted algae. It’s the go‑to option for anyone who wants peace of mind when adding fresh greenery to a carefully maintained setup.
Key Features & Benefits
- Thin, pointed leaves develop vivid salmon, fiery orange, and intense red tones under high-tech aquarium conditions.
- Unique cascading and arching growth habit naturally forms lush, overhanging bushes.
Care & Planting Instructions
-
Thoroughly wash away the nutrient gel from the roots with your fingers before parting it out into manageable portions. *Rotala leaves are thin and delicate, so handle stems with care during preparation.
- Use fine-tip pinsettes to plant small stem clusters 1 inch apart into aquarium soil.
- Provide high-intensity lighting and pressurized CO2 (20–30 ppm); combining strong light and regular iron dosing yields the deepest fiery red and orange coloration. See our guide to growing red aquarium plants.
- Maintain stable water parameters and avoid sudden parameter swings to prevent stem melting or rotting.
- Trim stem tops or side shoots with curved scissors once they reach the desired height, and replant trimmings directly into substrate to propagate and expand coverage. 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 H'ra to display fiery red and orange colors?
Achieving deep orange and red hues on Rotala H'ra requires high light intensity, mandatory pressurized CO2 injection (20–30 ppm), low-to-moderate water column nitrates, and regular micronutrient dosing with liquid iron. Under low light, the foliage will remain predominantly green.
3. How do I prepare Rotala H'ra Aquatic Farmer Tissue Culture before planting?
Carefully remove the gel from the roots by washing the plant in a bowl of room-temperature water or gently rinsing it under a tap. Once the gel is removed, separate the dense cluster into smaller clumps or individual stems and plant them into substrate using fine pinsettes.
