Alternanthera cardinalis is a striking red-purple aquarium stem plant that adds strong contrast to planted tanks. It is a popular choice when you want to break up green layouts and introduce more depth, colour and visual impact. Best used in the midground or background, this plant can reach up to 50 cm in height and works especially well when planted in groups. As the stems grow in together, they create a fuller, more dramatic display that stands out in both natural and more styled aquascapes. To keep its colour at its best, Alternanthera cardinalis appreciates good lighting, regular micronutrient dosing and a stable planted-tank setup. CO2 is highly recommended for the strongest growth and richer red-purple tones, but even in simpler setups it can still make a noticeable impact with the right care. You’ll receive a healthy rooted plant in a 5 cm pot, similar to those shown. Each plant is checked before dispatch.
