Radican Sword - Echinodorus cordifolius - Large

Radican Swords (Echinodorus cordifolius) have long sturdy stems and large, oval shaped leaves. They are uniform and bright green in color. Radicans are hardy once the roots are established, growing full and tall thus serving as terrific centerpiece or background plants. They have minimal requirements, mainly moderate to high light and plenty of space to expand.

"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.
