Alternanthera reineckii ‘Rosanervig’

Alternanthera reineckii 'Rosanervig' is a highly ornamental aquatic stem plant prized for its vivid pink to magenta foliage, highlighted by distinctive pale venation that creates a dramatic visual effect in aquascapes. This cultivar stands out as a focal point, bringing rich color contrast and depth to both modern and nature-style aquarium layouts.

With a moderate growth rate, Alternanthera reineckii 'Rosanervig' requires high lighting intensity and consistent CO₂ supplementation to maintain its compact form and enhance its vibrant pigmentation. A nutrient-rich substrate, along with regular dosing of macronutrients (NPK) and micronutrients—especially iron (Fe)—is essential to support healthy growth and prevent color fading.

This plant has a relatively delicate stem structure compared to other varieties, so careful handling during planting and trimming is recommended to avoid damage. Under optimal submerged conditions, it can grow to a height of 20–30 cm (8–12 inches), making it well-suited as a background plant in smaller aquariums or a striking midground feature in larger tanks. Regular apical trimming encourages bushier, more compact growth.

Propagation is simple and typical of stem plants: healthy cuttings from the top or side shoots can be replanted directly into the substrate, where they will root and continue to grow.

Perfect for aquascapers seeking bold coloration and visual impact, Alternanthera reineckii 'Rosanervig' elevates any planted aquarium with its intense hues and elegant structure.
