Arethusa bulbosa L.
Common Name: ARETHUSA, DRAGON'S MOUTH
Coefficient of Conservatism: 10
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb

Open bog mats, generally in sphagnum, hummocks in fens, coniferous (cedar, black spruce, tamarack) swamps, and in similar peaty situations.

One of the handsomest of our native orchids, becoming quite rare and local, especially in southern Michigan, thanks to destruction of habitats as well as to poaching. Blooms a little earlier than Calopogon tuberosus and Pogonia ophioglossoides, which are often in the same sites.
