Phlox nivalis is a species of flowering plant in the Polemoniaceae family with the common names trailing phlox and pineland phlox. It is native to the southeastern United States, Texas, Michigan, and Utah.[4]

One subspecies of this plant, Phlox nivalis subsp. texensis, the Texas trailing phlox or Texan phlox, is a rare plant federally listed as an endangered species of the United States.[5] The subspecies is endemic to Texas, where there are populations in three counties.[6] At one time, the subspecies was thought to be extinct. It was rediscovered in 1972.[5]
