Dragon's Mouth Orchid is a native perennial herbaceous wildflower in the orchid family that is native from Canada south to the Carolinas. It is found the mountains of North Carolina and prefers boggy sites, swamps, wet meadows and especially sphagnum bogs. It is generally a small plant, growing to a foot tall, although it has been known to reach 3 feet. It features a smooth stalk bearing tubular sheathing, nearly bladeless leaves, and topped by a single fragrant pink flower per stem. It blossoms in spring to early summer with the grass-like leaf following. They are easy to overlook in their native habitat.
The plant is named for the fountain nymph Arethusa and the flower suggests an animal's open mouth. The unusual lip-like petal serves as a platform for insects, especially bumblebees, that enter the flower for nectar and leave with powdery pollen masses.
It is considered endangered and listed as "critically imperiled" in North Carolina. Transplanting this orchid from the wild is rarely successful and they are generally not sold commercially.
