The Scarlet Temple arrived fresh and the colors are vivid. I’ve had it in my tank for three months and it’s grown quite bushy. The red tones stand out well against my background plants. Easy to maintain with regular light and a bit of CO2.

Great plant for adding bold color. It grows fast and spreads well in the midground. I trimmed it once and it responded well with new side shoots. Needs good lighting though, not ideal for low-light tanks.
