Marsh helleborine

Marsh helleborine is a typical species of Molinia meadows on calcareous, peaty or clayey-silt-laden soils (6410) and alkaline fens (7230). It is therefor an indicator of a good condition of these vegetations.

The species can also be found in alkaline humid dune slacks. It is a rare species. If its habitat dessicates or becomes acidic, the species will quickly disappear.
