Broadleaf Chain Sword - Echinodorus quadricostatus

The Broadleaf Chain Sword (Echinodorus quadricostatus) is one of the most compact of the Echinodorus swords. They have broad, almost grass-like leaves and will spread by sending out runners with new miniature plants that can be allowed to root in plant or be separated from the parent plant and replanted elsewhere. They are fairly undemanding but do need plenty of nutrients to remain healthy; without the proper nutrients, the leaves will be very thin or light in color. This plant is very similar to but has a slightly broader leaf than the "other" Chain Sword, E. tenellus (usually called the Narrowleaf Chain Sword).

"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 30 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.
