Grass of Parnassus is also the title of a book of poetry by Andrew Lang.

The genus Parnassia, also known as Grass of Parnassus or bog-stars, are plants in the family Celastraceae. The plants occur in arctic and alpine habitats, as well as in dune systems and fens, swamps, wet meadows, open seepage areas, moist woods, and across the Northern Hemisphere. It is actually not a grass, but an herbaceous dicot. The stalk of the plant can reach up to , the leaves up to and the petals can be up to wide. The flower has five white petals with light green venation. There are five three-pronged sterile stamens, each tipped with drop-like, false nectaries, which (along with the visual cue of veins) attract pollinating flies and bees.
