The opposite-leaved pondweed is probably one of the rarest pondweeds in Central Europe, so it is very rarely available in nurseries. Its demands are high: it prefers absolute unpolluted water, containing few nurtrients and - if possible - flowing. Where it is happy, it will develope large clumps. It never produces floating leaves, only the flowers and fruits can be seen above the water surface. When used in a garden pond, the best siting will be in an artifical creek.
