Dennerle - Alternanthera reineckii 'Red Ruby' is available for pre-order – please confirm stock before ordering!
Alternanthera reineckii 'Red Ruby' is a richly coloured stem plant known for its intense red foliage and distinctive lighter ruby-red venation. It creates a strong focal point in planted aquariums and contrasts beautifully with bright green stems, carpeting plants, and dark hardscape.
The cultivar grows at a moderate rate and develops its best colour under good lighting, steady COâ‚‚, and balanced fertilisation. It can be used as a compact group in smaller aquariums or planted in a larger stand through the midground and background for a dramatic red accent.

This plant is supplied in Dennerle Plant Bag format. Remove the plant material from the packaging, rinse gently, separate the stems where practical, and plant them individually or in small groups with a little space between stems. Trim and replant healthy tops to create a denser stand over time.
Please note: As this is a living plant, size, leaf shape, colour, and fullness may vary slightly from the product images and between individual specimens. Some emersed-grown leaves may change as the plant adapts to submerged aquarium growth.
