Ecology

This rhizomatous perennial has a very narrow habitat range, being confined to shallow, species-rich drainage ditches in lowland grazing marshes, where it typically grows in calcareous, mesotrophic or meso-eutrophic water. Although it fruits relatively freely and also produces turions, it shows little or no propensity to colonise new habitats. Lowland.
