Easily mis-identified as : Narrow-Lipped Helleborine (Epipactis leptochila) and Broad-leaved Helleborine (Epipactis helleborine).

Dune Helleborine was once thought to be a variation of Narrow-Lipped Helleborine (Epipactis leptochila), hence its former name Epipactis leptochila var. dunensis but it is now known to be entirely separate in its own right. In many ways it is similar to Narrow-Lipped Helleborine, but there are important subtle differences.

Dune Helleborine cannot tolerate grazing by animals but tolerates growing on soils containated by heavy metals, it is a Metallophyte.
