Echinodorus grisebachii

No, the Amazon sword is considered one of the easiest aquarium plants and is a great choice for beginners. It adapts to most water conditions and does not need CO2. For the fullest growth, give it moderate to bright light and feed the roots with root tabs, since it is a heavy root feeder.

No, CO2 is not required. Amazon sword grows well in low tech tanks without added CO2. That said, it will grow faster and produce larger, fuller leaves in a high tech setup with CO2, strong light, and regular fertilization.

Plant it in the midground or background where it has room to grow. Amazon sword becomes a large plant, so give it space away from the front glass. Bury only the roots in the substrate and keep the crown, where the leaves meet the roots, above the soil line so it does not rot.

In an aquarium it commonly reaches around 12 to 16 inches tall, and larger under strong light with a rich substrate. Mature plants can send leaves to the surface and spread over a foot wide, so it is best suited to medium and large tanks where it can serve as a centerpiece.

You will receive a healthy medium potted or bare root Amazon sword with an established crown and several green leaves. Leaf size and count vary a little from plant to plant, and some outer leaves may show minor wear from shipping. New growth settles in quickly once planted in a nutrient rich substrate.
