A bog and wetland plant, the sole representative for the monotypic family Menyanthaceae, has a wide circum-polar boreal distribution and common in most of its expensive range. M. trifoliata prefers oligotrophic to mesotrophic bogs and fens, and also grows along lake margins. Due to its expansive rhizome the plant can develop into extended stands.

It flowers in late spring or early summer, depending on the altitude of the habitat. Flowers are clustered in open racemes to form erect inflorescences held well above the water surface. The corolla is densely covered with long bristles so the flowers appear to be fuzzy. Pollinators frequently visit the inflorescences.
