Description
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.

Is Alternanthera cardinalis difficult to grow?
It is moderately demanding. It requires high lighting and CO2 supplementation to develop its intense red-purple colouration and grow at its best.
Does Alternanthera cardinalis need CO2?
CO2 is highly recommended. Without it growth slows significantly and the plant may lose its vibrant red-purple colour, becoming pale and less attractive.
How tall does Alternanthera cardinalis grow?
With CO2 supplementation it can reach up to 50cm, making it well suited to midground and background placement in medium to large aquariums.
How do I keep Alternanthera cardinalis looking its best?
Provide high lighting, CO2, and regular micronutrient dosing. Without micronutrients the leaves will become pale. Plant in groups of two or more stems for maximum impact.
Where should I place Alternanthera cardinalis in my aquarium?
Place it in the midground or background. Planting in groups creates bold colour contrast and dramatic vertical interest that draws the eye through the aquascape.
