Alternanthera cardinalis is a very popular red aquarium plant, known for its contrasting colour and broad leaves. Cardinalis is a hard and vigorous plant that requires bright lighting. Excellent as a background plant, the cardinalis provides depth and contrast for smaller green midground or foreground plants. To get this best colours out of this plant, high light is required which can often make this tricky to grow. With good co2 infusion and regular nutrient dosing this plant will grow very well and reach the surface happily.
