The calypso orchid (calypso bulbosa), also known as the fairy slipper, is a species of orchid that is widely distributed throughout the circumpolar region, inhabiting Europe, Asia and North America. Despite its wide range, it can be very elusive and easily overlooked, as it is typically low to the ground (10-14 cm). They are very susceptible to disturbances in their environment and are therefore listed as endangered or threatened in some states as well as Scandinavia. If you walk slowly and look closely, you can find calypso orchids along some of the trails here at the the Eagle River Nature Center, just be sure to watch your step!
