The first results in cultivating are very promising. The plant is robust and grows easy
in a 'standard' potting medium. However the propagation seems to be rather low as only a
few runners are made in half a year. The is no experience yet in submersed cultivation
(aquarium) but probably it will do and it may an attractive plant by its truncated leaves.
