Epipactis helleborine
The species occur in temperate and subtropical climates of America, Asia, and Europe. These orchids grow in open spaces in forests, in undergrowth, on calcareous soils and are often found in wet dune-slacks near the sea. The only original American species is giant helleborine ("Epipactis gigantea"). One species from Europe, broad-leaved helleborine ("Epipactis helleborine"), is invasive in North America. Most species are protected.
