This orchid video from Estonia says about itself:

Hand pollination project of red helleborine (Cephalanthera rubra).
Translated from the Dutch botanists of the Werkgroep Europese Orchideeën:
Tuesday, November 18, 2014
In 2014, some members of the European Working Group Orchids did research into the occurrence of Cephalantheras, a rare group of orchids with dainty flowers, found mainly in South Limburg. Of Cephalanthera damasonium quite a few plants were found. Cephalanthera longifolia was found only at a few places. Disappointing was that Cephalanthera rubra was not found anywhere.
Counting Dutch orchids in winter: here.
