Alternanthera reineckii

Sponsored by

Red Mint, Alternanthera rosaefolia

Alternanthera reineckii originates from South America, where it is found along riversides in areas that are periodically flooded during the rainy season. The purple colour of the leaf undersides makes a strong contrast to the green aquatic plant species available in the trade, especially when planted in groups. This plant may be used for setting colour accents in the background of the aquarium and is very suitable for aquarium cultivation.

Distribution: Its native range is Bolivia to Brazil and North Argentina, and is distributed across South America. The widespread distribution in European countries began in 2007.

Aquarium equipment

The substrate has to be rich in nutrients and finely sandy. When first planting, make sure to leave a certain distance between the stems. The tank must not be less than 40 liters, min. height 50 cm. This plant needs to be pruned frequently.

Plant care

The ideal conditions are Medium to high light intensities (0.4-1 watt per litre) and fertilisation with CO2. Other than many red-pigmented plants, it prefers a nutrient-rich environment with high levels of nitrate (10mg/l and over) and phosphate (0.5 mg/l and over). In water with a lower nutrient content, fertilisation via the substrate may support the overall health of the plant.

Water care

The water may be soft to hard, and the pH does not play a significant role either. However, the plant tends to do better in slightly acidic water.
