Dactylorhiza majalis (western marsh orchid, broad-leaved marsh orchid, fan orchid, common marsh orchid, or Irish marsh orchid) is a terrestrial Eurasian orchid. The western marsh orchid grows mainly in nitrogen-poor marsh areas that consist of several plant communities. More rarely, it is found in fens. Its flowering period begins at lower elevations as early as the beginning of May and ends in higher elevations at the end of July. The lowest blossoms usually open even before the stem has reached its full height.
