The dark-red helleborine attracts pollinators with its vanilla-scented flowers. It lives in sparse forests with calcareous soil and on piled up rocky material poor in nutrients, such as road embankments. In Luxembourg, the dark-red helleborine is found in the Gutland, especially in the former open-cast mining areas of the south.
