Echinodorus Osiris Rubra, or the Red Melon Sword, is a popular, easy-to-grow Amazon Sword for aquariums, known for its large, rounded leaves that emerge copper-red/bronze and mature to green, offering vibrant color, especially under bright light, and fitting well in the background of planted tanks. This heavy root feeder is beginner-friendly, tolerates various water conditions, and propagates via plantlets on its flower stem, making it a staple for adding contrast in aquascapes.
