(Epipactis helleborine)

Species Description
Description:
A surprisingly sturdy and successful orchid that doesn't mind being near humans. While many orchids are finicky and rare, this species is a rugged traveler from Eurasia that has naturalized across North America. It is often called the "weed orchid" because of its ability to pop up in places you’d never expect to see such an exotic-looking flower.
Habitat in the ANF
In the Allegheny National Forest, this orchid is a true opportunist. You can find it in the shaded understory of hardwood forests, but it is just as likely to appear along the edges of gravel trails, in roadside ditches, or even near campgrounds and cabins. It is highly adaptable to different soil types, though it prefers the dappled sunlight of forest edges where the soil is slightly disturbed.
Ecology and the "Drunk" Bee Strategy
The Broad-leaved Helleborine has one of the most wild pollination strategies in the woods. Its flowers produce nectar that contains naturally occurring ethanol and other narcotic compounds. When wasps and bees visit for a drink, they actually become slightly intoxicated.
This "drunken" state makes the insects sluggish, causing them to linger on the flower much longer than usual. This ensures they stay long enough to successfully pick up or deposit the orchid’s pollen packets. It is the only orchid known to use a "happy hour" to get the job done!
Identification
The Leaves: Look for broad, lance-shaped leaves that clasp the stem. They have prominent parallel veins and are arranged spirally, becoming smaller as they move up the stalk.
The Flowers: The plant produces a tall spike (up to 3 feet) crowded with nodding, 1-inch flowers. The colors are subtle—a mix of dusty greens, purples, and brownish-pinks.
The Lip: The bottom petal (the lip) is shaped like a tiny, nectar-filled bowl, designed perfectly for a wasp to climb into.
The Stem: The entire stem is covered in fine, downy hairs and remains upright even after the flowers have faded and turned into seed pods.
