Chelone (plant) Chelone is a genus of four species of perennial herbaceous plants native to eastern North America. They all have similarly shaped flowers (which led to the name turtlehead due to their resemblance to the head of a turtle), which vary in color from white to red, purple or pink. "C. cuthbertii", "C. glabra", and "C. lyonii" are diploid and "C. obliqua" is either tetraploid or hexaploid.
