Orchid seeds contain no stored nutrients. Before they can develop, they must be infected by a specialized fungus that establishes a symbiotic relationship, sharing food and enzymes until the young plant can survive on its own. Coralroots, however, never become self-sufficient. Researchers have discovered that members of the genus Corallorhiza are parasitic orchids. They derive their nutrients from eating mycorrhizal fungi in the soil. While most plants make their own food with chlorophyll, Corallorhiza contains little or no chlorophyll. Despite the name, they have no roots but only hard, branched rhizomes that resemble coral. These plants will be found deep in coniferous forests and subalpine woods. They like rich humus and damp soils where a shaft of light reaches the forest floor. They tend to grow in clusters of many plants. or Spotted Coralroot Corallorhiza maculata var. maculata or Spotted Coralroot is named for its spotted lip. The flowers are purplish. The tri-lobed lip is white with purple spots. The leafless stem is purple to yellowish with the flowers on the top half. The flower may not open fully. The plant is usually self pollinating and all flowers bear fruit. The distribution of this orchid is wide. It can be found in British Columbia across Canada to Newfoundland; western, northern and northeastern United States, south to California, Arizona, New Mexico and Texas. Corallorhiza maculata var. maculata has two color variations:
 or Western Spotted Coralroot The distribution is British Columbia thru Newfoundland south to California; Arizona, New Mexico, Minnesota, New England and Virginia. This orchid grows in coniferous and mixed woods. Plants ranges from reddish to tan in color. The tri-lobed lip is white with redish-purple spots. Where Corallorhiza maculata var. maculata and Corallorhiza maculata var. occidentalis occur together Corallorhiza maculata var. occidentalis typically flowers 2–4 weeks earlier. Corallorhiza maculata var. occidentalis has four color variations:
 or Ozette Coralroot Corallorhiza maculata var. ozettensis or Ozette Coralroot was described in Washington State in 2001 by Ed Tish.

 or Striped Coralroot Corallorhiza striata var. straita or Striped Coralroot is called striped coral root because of the 3 purplish stripes on the sepals. This is the largest coralroot in North America. In my opinion, this is the prettiest coralroot. The flower is pink to yellowish-pink. The leafless stem is yellowish to magenta with the flowers on the top half. Albino forms occur naturally. In nature the plant will be pale yellow throughout. The distribution of this orchid is wide.
