Scarlet Temple Aquatic Plant

Scarlet Temple (Alternanthera reineckii) is a vibrant red stem aquarium plant prized for its striking magenta-red leaves that bring bold color and contrast to freshwater aquascapes. Its brilliant hues and structured growth make it one of the most popular red aquarium plants among aquascapers aiming for a dramatic, high-impact design.

Native to South America, the Scarlet Temple plant thrives under moderate to high lighting and rewards aquarists with intense red and purple tones, especially when supplemented with CO₂ and iron-rich fertilizers. It’s a fast-growing species ideal for midground or background placement, helping to create depth and vibrancy in planted tanks.

3. Space stems slightly apart to allow light to reach all leaves.
