A Dark Gothic Secret: North American Orchids and Their Pollinators

Thursday, August 6th, 2015

Have you ever been at a stop light and seen a butterfly sampling nectar from flowers in small container garden? Maybe you’ve seen bees darting flower to flower as you tend your garden. Or maybe, as you walk the city streets, you see other insects whizzing about the flowering weeds that struggle to survive in the cracks of our concrete jungle. Based on these experiences, you might think that flowers only get pollinated during the day. Here’s a secret, and it’s a dark, gothic secret: Pollination also occurs under the veil of night. Some plants, like orchids and their pollinators, live a life less ordinary.

The majority of North American orchids are pollinated during the daytime. But there are a few special orchids that are part of the pollination graveyard shift. In North America, the rare Ghost Orchid, Cranefly Orchid, Tall White Bog Orchid, Dingy Flowered Star Orchid and most of the orchids in the genus Platanthera are special orchids that are pollinated at night.
