Description[edit]

Epipactis helleborine grows to a height of 80 cms has broad dull green leaves which are strongly ribbed and flat. The flowers are arranged in a long drooping racemes with dull green sepals and shorter upper petals. The lower labellum is pale red and is much shorter than the upper petals.[3]

Distribution[edit]

It is widespread across much of Europe and Asia from Portugal to China, as well as northern Africa.[1][4][5] In North America, it is widely naturalized mostly in the Northeastern United States, eastern Canada and the Great Lakes Region, but also in scattered locations in other parts of the continent.[6][7][8]

Ecology[edit]

Found in woods and hedge-banks.[9] Eight varieties of Epipactis helleborine in central Europe (Lower Silesia, Poland) had their nectar studied and they were found to contain naturally occurring oxycodone (as well as another narcotic like opioid) in minute amounts.[10]
