The Calypso Orchid has an amazingly broad circumboreal distribution. From Japan to Mongolia, Scandinavia to Newfoundland, New Mexico to Alaska – this single species can be found in nearly every montane coniferous forest in the Northern Hemisphere. In spite of this C. bulbosa is considered endangered in Sweden, Finland, and several U.S. states due to its extreme sensitivity to even the slightest human disturbances.
