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.
