Hooded Coralroot, Striped Coralroot, Bigelow's Coral Root, Macrae's Coral Root, Madder Stripes
Orchidaceae (Orchid Family)
Synonym(s): Corallorrhiza striata
USDA Symbol: COST19
The orchids of genus Corallorhiza have no chlorophyll and are mycoheterotrophic; that is, they utilize fungi to parasitize the roots of other plants. 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. 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.
