Rooted mean that this plant was cultivated in soil and sent to you in soil
Why do we offer this plant in soil? 
Our research here at our facility reveals that plants previously grown in soil adapt more quickly to aquatic environments compared to those cultivated in regular rockwool pots. We attribute this to the closer resemblance to their natural evolutionary conditions.
 
What's the alternative to soil-planted plants? 
The standard option is plants potted in rockwool, commonly available at your local aquatic store. 
Additionally, during the summer months, we also provide submerged plants for most species.

Echinodorus palaefolius (Mexican sword)  differ from other amazon swords in the following aspects:
Stem – long
Leaf form/shape – oval 
Leaf size – long
Leaf colouration – green 
Height – 33cm + (15” +) regular pruning can keep them this small, but they tend to grow very large and out of the aquarium
 
Amazon swords – are mostly great accent plants that propagate through side shoots that can grow out of the water. They are a good beginner’s plant because their needs are so clearly described and if adhered to they will thrive.
What is this needs?
Nutrient rich soil or regular root tabs
MUST remove the cotton from the plant before planting
Moderate lighting
Stable water conditions
Limit any copper based medication as far as possible (some ICH meds use copper as active ingredient)
CO2 is not essential but good idea in high lighting aquariums
NOTE – They form massive root systems and this can cause other plants to suffer. An easy way to prevent this is to plant them in a reasonable size (IE 15cm – 6”) flat tray/pot, filled with good quality aqua soil, that you can burry in your substrate to hide it.
