Epipactis helleborine
Most of these hardy orchids grow in a wet environment, but there are exceptions. The marsh helleborine ("Epipactis palustris") is the only European orchid able to survive in a flooded habitat. "Epipactis gigantea" is a species found in the American west, and into southern Canada, in wet areas and even streams. It can grow to a height of 1 m. However, "Epipactis helleborine" grows in more diverse habitats, from sheltered sandy beaches to open spaces in deciduous or coniferous forests, on roadsides, in meadows, and on moist soils. It is sometimes called the weed orchid.
