This plant seems to have quite a short flowering season, appearing in late spring but most flowers, unless in mountain lakes, have disappeared by mid summer. It is easy to identify with its white hairy flowers. It loves wet places and most of the time the stems are actually in the water.

M. trifoliata is very common in the British Isles but being water loving plant is least common in the drier areas of eastern England and commonest in the west particularly the north west of Scotland. It is common throughout Ireland and Wales.
