Epipactis atrorubens, the Dark-red Helleborine or Royal Helleborine, is an herbaceous plant from the family Orchidaceae. The plant is hardy and has a short rootstalk, often with multiple, fleshy roots. It blooms from June to August with erect, mostly purple inflorescences with dense hair on the tops, standing between 20 and 80 cm in height. The blossoms emit a strong vanilla scent, especially in warm weather. The flowers sometimes vary in color, but are in general reddish-brown, and they are often pollinated by insects, particularly bees. The fruit is a capsule, out of which the light, dustlike seeds are spread by the wind. A number of natural hybrids with other Epipactis species are known.
