Parnassia palustris aka Grass Of Parnassus

Parnassia palustris, also known as the marsh grass of Parnassus, northern grass-of-Parnassus, or just grass-of-Parnassus, and bog star, is a flowering plant in the staff-vine family Celastraceae. Despite its name, it is not a grass and has a unique appearance. This perennial plant forms a rosette with heart-shaped basal leaves and can reach a height of up to 20cm. In late spring and early summer, it produces star-shaped white flowers with greenish veins, measuring approximately 2.5cm across. P. palustris, which is the county flower of Cumberland in England and featured on its flag, thrives in marshy habitats, as indicated by its Latin specific epithet "palustris" meaning "of the marsh." This plant was admired by the cattle on Mount Parnassus in ancient Greece, earning it the honorary title of "grass." The species was described by Dioscorides, a Greek physician, and has been found growing on mountains since the 1st century A.D. The flowering stem emerges from the center of the long-stemmed, heart-shaped leaves and holds a solitary white flower, which emits a honey-like scent to attract pollinators. Blooming from July to October, the flower features 5 stamens encircling its center.
