South America; these plants are found in Brazil.
Although this is a rhizome plant, division of the rhizome is not the only way this plant can be propagated. They will also develop adventitious plants around the mother plant. To propagate these it is simply a matter of prying them free from the rosette of leaves and re-planting them in the substrate. Ensure that they get nutrients added straight away to encourage the new root growth.
This is the largest of the Sword plants and needs to be grown in an open topped aquarium to allow the leaves to reach their maximum height. They prefer the higher end of the temperature range, keeping them at lower temperatures will reduce their growth rate and prevent them from flowering. In Brazil the leaves are dried out and used in herb medicines as they are supposed to relief symptoms of various common complaints.
