Most species are parasitic, relying entirely upon mycorrhizal fungi within their coral-shaped rhizomes for sustenance. Because of this dependence on myco-heterotrophy, they cannot be successfully cultivated. Most species are leafless and rootless. They do not produce chlorophyll, and do not utilize photosynthesis. An exception is the yellowish green species Corallorhiza trifida, which has some chlorophyll and is only partially dependent on its fungal associates for nutrition.
