Bacopa salzmannii purple
Bacopa salzmannii purple
Bacopa salzmannii purple is a spectacular color form of Bacopa salzmannii producing rich purple to deep reddish-purple submerged leaves that create a vivid and unusual color accent in the planted aquarium. Unlike most purple-toned aquarium plants that require extreme conditions, Bacopa salzmannii purple is relatively achievable under high lighting with CO₂, making it accessible to hobbyists who have mastered basic high-tech planted tank technique.
Care tip: Bacopa salzmannii purple grows best in high lighting with CO₂ recommended. Maintain temperatures of 72–82°F and pH 6.0–7.2. Regular liquid fertilization supports healthy growth and best coloration.
Growing to 6 to 12 inches, this variety is suited to midground placement where its distinctive purple coloration can be displayed effectively. Regular trimming maintains compact growth and ensures fresh, vividly colored new growth is consistently produced. As the chart notes, the plant is emersed-grown and typically arrives green — the rich purple color develops after submersion under appropriate aquarium conditions.
High lighting is essential for the best purple coloration, and CO₂ supplementation is strongly recommended — without CO₂ the plant remains green regardless of lighting intensity. Temperatures between 72 and 82°F and a pH of 6.0 to 7.2 provide ideal conditions. Regular fertilization with micronutrients and iron supports the development and maintenance of the purple pigmentation after the plant has established itself submersed.
In the aquascape, Bacopa salzmannii purple provides an unusual cool-toned color accent that contrasts beautifully with warm reds and greens. The purple tones pair naturally with green mosses and pale substrate, and create interesting color relationships with red Alternanthera or Ammannia. It is a standout specimen in the midground of any high-tech planted aquarium.
Bacopa salzmannii purple is a rewarding high-tech plant for aquarists who want genuine purple color in the midground without the most extreme demanding conditions. Its color transformation from green to rich purple after submersion is one of the most satisfying developments in the planted tank hobby.
