Flowering - June - July.

Habitat - Fens.

Origin - Native to U.S.

Other info. - This striking little orchid is exceedingly rare in Missouri, being found in only two locations. The plant is fen obligate and does not seem to compete well with larger more aggressive plants. Because of this, fire seems to help the plant become more established. As fire finds its way back into forest management, this species could be found in more areas of the state.
