These are amphibious plants that can be cultivated in flowerpots. Their leaves
are sturdy and their growth is slow but regular.
The spathy usually dies within a few months if it is permanently underwater.
However, some aquarists manage to keep them alive for longer periods, without any
apparent explanation. Nevertheless, it is best to cultivate this plant partly outside
water - which should be soft and slightly acid - for a few months if you have kept
it totally submerged. Size: 40 cm.
