M. trifoliata is a rhizomatous perennial which grows as an emergent at the shallow edge of lakes, pools or slow-flowing rivers, or in swamps, flushes or dune-slacks. It tolerates a wide range of water chemistry, but is intolerant of shade. 0-1005 m (Beinn Heasgarnich, Mid Perth).
Although this species remains frequent over much of our area, it has decreased in S.E. England because of the drainage of wetlands in both historic and recent times. In some of these areas it is now more frequent as a planted ornamental than as a native.
Circumpolar Boreo-temperate element.
