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.[6] The subspecies is endemic to Texas, where there are populations in three counties.[7] At one time, the subspecies was thought to be extinct. It was rediscovered in 1972.[6]
