Description
Plant Profile
Alternanthera Reineckii Rosanervig, also widely known as Variegated AR, is a distinct cultivar of the beloved South American stem plant family. Famous for its variegated leaves that display a magenta-to-deep-pink body accented by bright, silvery-white leaf veins, this variety brings detail and visual texture to planted aquariums. Slightly softer and more delicate in stem structure than standard Alternanthera reineckii variants, AR Rosanervig functions as a captivating background plant in nano setups or a dramatic midground focal point in larger, high-tech Dutch and nature aquascapes.
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
Bold foliage with distinct light-colored veins provides visual interest and contrast.
Densely leaved plants offer protective cover for sensitive dwarf shrimp and shy fish.
Care & Planting Instructions
Thoroughly wash away the nutrient gel from the roots with your fingers before parting it out into manageable portions. *AR Rosanervig stems are soft and delicate, so handle with care during preparation.
Use fine-tip pinsettes to plant small stem clusters 1 inch apart into aquarium soil.
Provide medium-to-high lighting. Adding pressurized CO2 injection and regular micronutrient dosing with liquid iron ensures maximum pink coloration and strong vein contrast. 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 stems reach the desired height, and replant trimmings directly into substrate to propagate and thicken the bush. 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 light 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 keep AR Rosanervig displaying its distinct pink veins?
Providing medium-to-high light intensity, pressurized CO2, a nutrient-dense substrate, and regular micronutrient dosing with liquid iron ensures vivid pink leaf coloration while keeping the white vein-like patterns distinct and sharp.
3. How do I prepare Alternanthera Reineckii Rosanervig UNS 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.
