Care Tips: Lobelia cardinalis is a popular and attractive aquarium plant known for its lush green, lance-shaped leaves and vibrant red coloration in high light. It thrives under medium to high lighting conditions and benefits from CO₂ supplementation for robust growth. The plant prefers slightly acidic to neutral water and nutrient-rich substrates. Regular pruning helps to maintain a bushy, compact shape and prevents leggy growth. It works well in the midground to background of aquariums and can be used to create colorful, densely planted areas. Regular water changes and proper nutrient management are essential for optimal growth.
