Quick Summary

The term "large white helleborine" refers to a specific species of orchid, Cephalanthera damasonium, belonging to the genus Cephalanthera. Helleborines, in general, are orchids from the genera Cephalanthera and Epipactis.1

Key characteristics of Cephalanthera species, including the large white helleborine, include tall, thin stems, crinkled leaves, and large white or bright pink flowers that are held erect and lack stalks. The large white helleborine is notable for being self-pollinating, meaning it does not rely on insects for this process, unlike most other helleborines. This species is common in Britain and has numerous long, thick roots, with petals that are held close together, giving the flower a closed appearance.1
