Epipactis helleborine (L.) Crantz
Common Name: HELLEBORINE
Coefficient of Conservatism: *
Coefficient of Wetness: 0
Wetness Index: FAC
Physiognomy: Ad P-Forb

Primarily deciduous forests, hemlock-hardwoods, and mixed forests; but now established in a wide range of habitats, even including as a weed in gardens and yards. Naturalized from Europe; spreading aggressively in Michigan. The first Michigan record was from 1919, in Berrien Co., but now Epipactis is the commonest orchid in much of the State.

The lip, lateral petals, and sepals are quite variable in color; the petals and sepals range from pale greenish through green to deep purple and the lip from white to quite pink. Ghostly white plants, apparently lacking any pigments, are known.
