Minuartia carolinanana, or the Pine-barren sandwort is a small plant in the Pink family (Caryophyllaceae) native to the eastern coast of the US. They are found growing on white sands of pine barrens. They usually grow alone or with some grasses. The leaves are small and grow along the stem, resembling some moss species in both size and shape. The flowers grow out of these stems in long branches with five-petaled flowers that can grow longer than the stems supporting them.
