This species grows in a wide range of meso-eutrophic or eutrophic and often calcareous waters. These include lakes, ponds, rivers, canals and ditches. It may persist in managed ditches and rivers and colonises newly flooded mineral workings. It also grows in slightly brackish sites. 0-390 m (Drumore Loch, E. Perth).
This is the commonest Myriophyllum species in the eutrophic lowlands of Britain and in some areas of Ireland. Like many aquatic plants it is better recorded now than in the 1962 Atlas.
Eurasian Temperate element, but naturalised in N. America so distribution is now Circumpolar Temperate.
