Bacopa salzmannii sp araguaia
Bacopa salzmannii sp araguaia is a collector's variety of Bacopa salzmannii known for its ability to develop spectacular purple-pink hues under the right aquarium conditions. This variety arrives in its emersed form as green-leaved stems but transforms into a display of pink to purple coloration after acclimating to submersed aquarium life under strong lighting with CO₂ support — one of the most satisfying color transformations available in the planted tank hobby.
Care tip: Bacopa salzmannii sp araguaia grows best in high lighting with CO₂ recommended. Maintain temperatures of 72–82°F and pH 6.0–7.0. Regular liquid fertilization supports healthy growth and best coloration.
Growing to 8 to 12 inches, Bacopa salzmannii sp araguaia is suited to background placement where its upright stems can develop fully and the color transformation can be appreciated from a distance. Regular trimming after the plant is established and colored up produces branching growth and denser, more vivid groupings. As with all Bacopa, propagation from trimmed tops is straightforward and reliable.
CO₂ supplementation is recommended for this variety — without it, the plant remains green regardless of lighting intensity, and the distinctive purple-pink color that makes this plant worth keeping never develops. High lighting is also required for the best color. Temperatures between 72 and 82°F and a pH of 6.0 to 7.0 provide ideal conditions. Regular fertilization with micronutrients supports the development of the pink-purple pigmentation.
In the aquascape, Bacopa salzmannii sp araguaia provides a cool purple-pink background color that is quite different from the typical warm reds of Alternanthera and Ammannia. The purple-pink tones complement green foreground plants and create a natural color harmony with other cool-toned midground plants. It is a distinctive background species that adds color variety beyond the usual red-and-green palette.
Bacopa salzmannii sp araguaia is a rewarding plant for aquarists with CO₂-enriched tanks who want unusual purple-pink color in the background. The color transformation from green to purple-pink is one of the hobby's great botanical rewards.
