Oenanthe aquatica, known in English as fineleaf water dropwort, fine-leaved water dropwort, fine leaved water dropwort, fineleaf water-dropwort, fine-leaved water-dropwort or fine leaved water-dropwort is an aquatic flowering plant in the Apiaceae.
Habitat and distribution
It is native to Europe, found in wetlands, in still or slow-moving water, from Sweden in the north to Sicily in the south and from Ireland in the west to Russia in the east. It has also been recorded in East Asia.
It grows particularly well in bodies of water with deep eutrophic silt and where the water level is very variable, for example in shallow ponds and ditches, but is also found on lakes, reservoirs, canals, streams and rivers, in marshes and seasonally flooded depressions. It is limited to low altitudes and cannot tolerate saltwater.
