Melon Sword - Echinodorus osiris - Small

The Melon Sword (Echinodorus martii) has green broad leaves. The younger center leaves have a reddish tint to them and turn green as the plant matures. They are generally more difficult then other swords to keep healthy and need additional plant supplements such as iron is also recommended to keep these plants looking their best. They can be kept in soft or hard water and are best as a background or midground plant.

"Sword Plants" come primarily from the Echinodorus genus and are marsh or bog plants from the tropical western hemisphere (North, South and Central America as well as some islands in the region). While there are around 3 scientifically accepted species, many species are cross-bred and propagated by hobbyists and nurseries to create numerous variants and hybrids.

While swords may grow emerged in the wild (with their leaves out of the water), they are well adapted to submerged life in the aquarium as well. Emerged plants grow flowers, while submerged plants will reproduce by sending out runners to grow new plants. Most swords need high lighting to thrive. They also benefit from a nutrient-rich substrate and iron and CO₂ supplements, especially in heavily planted aquariums.
