Cultivation details
We have very little information on this species and do not know if it will be hardy outdoors in Britain. However, judging by the plants native range, it is likely to succeed outdoors at least in the warmer areas of the country. The following notes are based on the general needs of the genus. An aquatic plant, floating by means of inflated petioles, it succeeds in still or slowly-flowing water requiring a position in full sun and a slightly acidic water with a rich planting medium[200]. Plants require a high summer temperature in order to perform well, they are not frost hardy[206].
Propagation
Seed - harvest in late summer and store overwinter in a jar of water in a cold but frost-free place. The seed quickly loses its vitality if it is allowed to become dry. Sow in spring, placing one seed in each pot and submerging them under a few centimetres of water.
