The Amazon Sword Plant, Echinodorus amazonicus, has short rhizomes, numerous lance shaped leaves that are pale to dark green with sharply pointed tips, and fairly short stems. They are capable of reaching approximately 20 inches in height under proper water conditions. This plant is amphibious and will grow either partially or fully submersed.
This plant will get too big for small aquariums but E. amazonicus can be forced to stay a little smaller by not using CO2 and limiting nutrients in the substrate. For best results provide a loose substrate and an iron-rich fertilizer.This plant can be kept as a pond plant when over night air temperatures stay above 50F.
Propagation of this Plant is carried out by adventitious roots or by runner. When you can see roots on the plantlets, gently twist them off the runner and plant them in the substrate. If you want more plantlets it is important not to injure the runner, because a good runner can produce plantlets many times.
