Cultivation & Habitat

Seed – we have no information on this species but, since it can spread rapidly by division, it really needs no extra help once it is in a pond.
A pond plant, floating on the surface of the water, it requires a sunny position in still water that is rich in nitrates and lime[200]. At the limit of its climatic range in Britain and probably best grown in a cold water aquarium[200]. It over-winters in temperate areas by means of resting buds which sink to the bottom of the pond in the late autumn and rise again in the spring[200]. One of the smallest flowering plants in the world, it is cultivated as a vegetable in Burma, Laos and Thailand[183]. It has been recommended for commercial cultivation, especially in tropical areas, because of its rapid multiplication and high nutritional value[183]. Plant densities of over two million plants per square metre have been found[274].
