During fall cleanup how far back can I cut?
How lovely that you have a Turtlehead or Chelone to give you a splash of colour in the late summer. Have you tried bringing them in as cut flowers? They should last at least four weeks indoors with a bit of tender loving care.
Chelone is a perennial wildflower that likes damp soil. It has a rhizome root system. There are several species with hardiness ranging from zones 3 – 7. Colours range from pink to purple to white. Chelone glabra is native to parts of Canada including Ontario.
Leave the spent foliage of the plant over the winter to avoid damage to the plant’s crown from harsh weather. Remove in early spring. New stems will grow from the rhizomes in the spring.
