Corallorhiza striata Lindl.
Hooded coralroot, Striped coralroot, Bigelow's coral root, Macrae's coral root, Madder stripes
Synonym(s): Corallorrhiza striata
USDA Symbol: cost19
USDA Native Status: L48 (N), CAN (N)
A nearly leafless plant with several or many erect, reddish-purple stems bearing several or many reddish-striped, pale pinkish, bilaterally symmetrical flowers in a raceme.
Corallorhiza means coral root, though the root is actually a hard mass of rhizomes associated with a fungus that aids in absorbing nutrients from the humus on the forest floor. (Coral roots lack chlorophyll and thus get nourishment from organic material in the soil.) After producing flower stalks, the rhizomes may remain dormant for several years. The most attractive of several coral roots, this orchid can withstand cold but not heat and thus cannot be successfully cultivated south of its natural range.
