About

Cephalanthera longifolia, the narrow-leaved helleborine, sword-leaved helleborine or long-leaved helleborine, is a rhizomatous herbaceous perennial plant in the family Orchidaceae. It is native to light woodland, and widespread across Europe, Asia and North Africa from Ireland and Morocco to China. This includes the United Kingdom, Iran, Russia, Kazakhstan, Turkey, Algeria, India, Pakistan, Germany, Italy, France, Spain, Portugal and many other countries.

Where it grows

The flowers are pollinated by solitary burrowing bees. The flowers produce little nectar and the yellowish dust on the labellum which the insects collect is of little nutritional value. The actual pollen is contained in two pollinia which adhere to the hairs on the bee's back.
