Marsh Grass-of-Parnassus

Parnassia palustris

Also known as Northern Grass-of-Parnassus, Bog Star, Grass-of-Parnassus

Marsh grass-of-Parnassus produces solitary, star-like white blossoms lined with distinctive translucent green veins. Each flower features specialized sterile stamens tipped with shiny yellow knobs that visually mimic drops of nectar to attract pollinating flies and bees. This perennial wildflower thrives in cold, wet habitats across northern regions, including fens, bogs, and damp mountain slopes.

Support conservation
Observe from established trails or boardwalks to avoid damaging fragile bog soils and surrounding vegetation.
Responsible observation
