Scarlet Temple (Alternanthera reineckii) — Live Aquarium Plant
Scarlet Temple is a striking red stem plant native to the marshes and slow-moving waters of South America, from northern Brazil down into Argentina. Its vivid red to maroon coloring comes through best under moderate to high lighting, and while CO2 isn’t required, added CO2 and a nutrient-rich substrate bring out deeper color and faster growth. It grows upright in a bushy habit, typically reaching 8 to 20 inches, and responds well to regular trimming, which encourages fuller, denser growth rather than leggy stems. Trimmed cuttings can be replanted directly into the substrate to fill in bare spots or start new clusters.

The plant has vibrant red stems and grows well in my 5-gallon tank with moderate lighting. I trim it every few weeks and it fills out nicely. Very satisfying to watch it grow.
Owen Morrison –
It’s a beautiful addition to my planted tank. The color is intense and stands out well. I didn’t add CO2, but the color is still quite vivid after a few weeks.

Easy to care for and grows quickly. I used it to fill a sparse area in my tank and now it’s a dense bush. The trimming process is simple and effective.
