Classified as Vulnerable in Britain, where it is confined to northern England and Scotland, Coralroot Orchid is tiny and inconspicuous and therefore difficult to spot. The plant lacks leaves (it has a few scale-like sheaths on the stem) and is entirely dependent on a relationship with fungi during its life. Corallorhiza trifida grows in moist but not overly wet habitats and is tolerant of various light conditions from dark woodland to lightly shaded or open sunny positions. It is most commonly associated with willow and alder carr (occasionally birch and pine trees) with which the fungi it depends upon forms mycorrhizal relationships. In North America several species of Corallorhiza orchids are found in pine woodland. Corallorhiza trifida flowers from May to August. On mainland Europe this orchid occurs widely in the north, and its range extends southwards to France and Corsica. Both the English common name and the scientific name refer to the appearance of the rhizome, which is said to resemble coral.

Possibly pollinated by small insects, but self pollination is more common. |
The specific name trifida means 'split into three' and is said to refer to the lip of the flower, although it is barely tri-lobed. |
