Sword Plants Facts

This plant can grow up to three feet tall in the wild but in their most common form for the aquarium, stay around 10-12”.

Echinodorus spp. require Co2-enriched planting substrate and lots of light to thrive. This plant family can be propagated by dividing the rhizome or by planting one of its many readily available seeds.


Aquatic Sword Plants have large and wide leaves with pointed tips that resemble swords, hence their common name.

Depending on the species, the leaves can range in color from green to bronze, with veins of a darker shade.

Fish use the Sword Plant’s rosettes as a great hiding spot, so be sure to offer plenty of choices when deciding how to decorate your aquarium.


Echinodorus spp. is native to tropical and subtropical regions of the Americas and Africa, typically found in wet and marshy ground, shallow submerged swamps, or temporary streams.

These plants thrive in warmer climates with high levels of oxygen in the water, making them well-suited for aquariums. 

pH Preference

Echinodorus spp. prefer an acidic pH level of 6.0 to 8.0, however, they have the ability to adapt to more alkaline water. To maintain a more specific pH, add daily water changes of around 25-30%.

Vivarium Type

Sword Plants are quite easy-going as a species. With that in mind, it will not be too complicated when it comes to choosing the type of enclosure it is grown in. It is best to try and replicate the plant’s natural habitat as much as possible.

Doing so will make it easier to provide this foliage plant with its basic needs. The proper setup and theme of the enclosure will make a big difference to the overall look and health of the plant. Be sure to choose setups that are moist and high in humidity.

Here are recommended vivariums it will do well in:

  • Paludariums – Half aquatic/ half terrain-based enclosure.
  • Ripariums – Mostly aquatic-based enclosures with some terrain features present.
  • Aquarium– Fully aquatic-based enclosure with little to no dry terrain.

Vivarium Placement

Sword Plants will best fit in any submerged environment. Be sure to plant them in a Co2-enriched substrate as well as add directly soluble nutrients such as fertilizer.

These plants can also be planted on a normal substrate and in heavy tangles to give a feeling of a wild river bed. Be sure to leave enough space between them to allow water to flow throughout their aquarium.


Echinodorus spp. prefer a Co2-enriched substrate, however, they can adapt to a variety of environments with varied pH and hardness ranges.

An enriched aquatic substrate will ensure that the Sword Plant receives all the needed nutrients to grow and keep the environment in balance. 


Aquatic Sword Plants need a good amount of lighting for proper growth.

Adding medium aquarium lighting for 8-10 hours a day will provide the most natural habitat for the plant and prevent the excessive growth of algae.

Investing in LED lights or metal halide lamps for a brighter light level will really bring out the vibrant color of the leaves. 

Buy A Sword Plant

When it comes to buying Echinodorus spp., there are a few things to keep in mind. Making sure the plant is healthy when purchased is essential for its success in a vivarium or pond. Vegetation that is already in poor conditions will have a very hard time adjusting to new environments.

Sword Plants Care & Propagation

Regular pruning of the leaves is recommended to give your Sword Plants an even and appealing look.

Trimming away old and decaying leaves will reduce bacterial and fungal growth in the tank and give new leaves the resources to grow properly.

Propagation can be done through the division of the rhizome or through the planting of seeds, which are readily available online.

How To Grow

Sword Plants are relatively easy to grow and require minimal maintenance, making them easy and fun to take care of.

Soil should be nutrient-rich and loosely mixed, to ensure the growth of roots and stems.

Ensure to add fertilizer weekly or bi-weekly to keep these plants healthy and growing and monitor nitrogen levels, as too much can lead to slower growth.

Water Requirements

Echinodorus spp. prefer an acidic water temperature ranging from 50-86°F.

Water should be changed weekly or more if necessary to keep the environment fresh, as this will help prevent a buildup of nutrient levels in the tank.

Plants Similar To Sword Plants

Adding diversity to an enclosure is key to an aesthetically pleasing setup. Try mixing up the look of your vivarium with different flora that can easily co-exist in the same types of environment.
