Fen Grass of Parnassus is a delicate wildflower of calcareous wetlands, fens, and wet cliffs, producing single white flowers with intricate greenish veins on long slender stems. It grows in cold, calcium-rich, nutrient-poor habitats and is an indicator of high-quality fen conditions. Small bees and flies pollinate it.
