Chelone glabra, or Turtlehead, has showy spikes of 2", hooded snapdragon-like flowers that resemble a turtle's head. The blooms of Chelone glabra are sometimes tinged with pink. Chelone glabra forms dense clumps of crisp, dark green foliage.
Turtlehead grows best in sun with moist, even boggy soil but will adapt to drier soil and tolerates clay soil. A native to the eastern half of N. America, it is attractive to hummingbirds and to butterflies for which it is a larval host. It will naturalize where happy.
