Spade Leaf Sword
This plant is found in boggy areas of Mexico and also in North America.
If grown as a terrestrial plant it will produce flower stalks and the flowers can easily be brushed with a small paintbrush to fertilise them. In the aquarium flower stalks will not be produced but adventitious plants will be formed 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.
These plants can grow quite large so are more suitable for a larger aquarium. They require a substrate that is rich in nutrients and bright lighting. They will display a marbled leaf surface once they have settled into the tank but it is quite normal for many if the leaves die back initially and then re-grow.
