Large-leaf Grass of Parnassus - Parnassia grandifolia
Despite its common name, Parnassia grandifolia (Celastrales - Celastraceae) is not a grass, but a perennial herb, forming clusters of slightly succulent, shiny leaves. Its large, white flowers with green veins and bright orange anthers are really beautiful.
Parnassia grandifolia is native to central and south eastern US. It grows in alkaline seeps and is an indicator of rich, old forest.
