Joe Fehrer, manager of Nassawango Nature Preserve on Maryland’s Eastern Shore in the US, has set the rules: No photos of the horizon or any landscape feature that might identify this place. No naming the back road that leads here. The obsessive cone of silence around this precise location has nothing to do with nuclear codes or terrorist cells. The mission here is to protect a flower. An orchid.

Fehrer’s job is to stay one step ahead of the orchid thief. The flower Fehrer is defending is Platanthera x canbyi, or Canby’s bog orchid, a rare hybrid born of two rare parent orchids. This flower hasn’t been seen in Maryland in almost 20 years. Fehrer would much rather that the rest of the world take it on faith that this fragile and rare orchid has reappeared on the Eastern Shore. To believe without seeing. He is taking a reporter to see the orchid only reluctantly, he says, running the risk that the crazy “orchid heads” will sneak out here, trample the delicate habitat or, worse, haul out a garden trowel, dig up the precious hybrid and steal it away to become a prized possession in some private collection rather than the start of a fledgling colony in the wild.

“They come here and search out rare orchids for their own gratification and remove them,” he said. “Which makes them all the more rare. We need to be careful. Some of these folks are real sleuths.”

Just past a clump of huckleberry bushes ripe with purple berries, Ron Wilson, a former high school science teacher-turned-professional botanist, held his bright yellow global positioning device close to his face, the better to read the plot points he recorded a few weeks ago when he discovered the hybrid.
