Helleborine Drugs Its Visitors

7-29-13 helleborine 029Helleborine (Epipactis helleborine) is a common woodland plant which is easily overlooked due to its inconspicuous, small, greenish-purple flowers. However, this modest member of the Orchid family brings pollination to a new level. Its structure is said to not be morphologically attractive to insects, so Helleborine has come up with another strategy to get its flowers pollinated. It produces nectar that contains several chemicals, including oxycodone, a drug which has a morphine-like effect on organisms that ingest it. When insects drink the oxycodone-laced nectar, they become sluggish, which prolongs the amount of time they spend at the flower, which, in turn, increases the chances that the flower will be pollinated.
