This association is dominated by Nasturtium officinale, rarely also by N. microphyllum or N.×sterile. It occurs in brooks, channels, ditches, pools and small fishponds. The water is usually 5–40 cm deep, but the water table can recede to expose the bottom for short periods, provided that the substrate remains wet. In deep moving water Nasturtium stands can float freely on the water surface. This association occurs in lowland areas with base-rich bedrock, most frequently in central Bohemia, and also in eastern Bohemia and southern Moravia.
