Fire Pink (Silene viginica) is definitely not pink, but very bright red. The word pink refers to its membership in the pink family, with notches in each of the five flower petals.
This distinctive wildflower blooms in April and can usually be found along the Chestnut Top Trail near Townsend in the Great Smoky Mountains National Park.
