Echinodorus ‘Red Rubin’ is a striking ornamental sword plant prized for its long, elegant leaves and rich red coloration. New foliage can develop beautiful shades of ruby red, burgundy, bronze, and copper, while mature leaves may gradually become deeper green with reddish tones. Its impressive rosette growth makes it an excellent centerpiece or background plant for medium to large freshwater aquariums. Moderate to strong lighting, a nutrient-rich substrate, and balanced fertilization help promote healthy growth and vibrant coloration. Supplemental CO₂ can encourage faster, fuller development. With its bold colors and graceful form, ‘Red Rubin’ creates dramatic contrast and a beautiful focal point in planted aquascapes.
