Ghost Orchid

The supernatural glow of the mysterious ghost orchid is back in the Everglades for the third year in a row. This flower rarely blooms two years in a row, and was missing for a dozen years until 2007.

The ghost orchid, of course, is the haunting beauty featured in the book The Orchid Thief and the bizarre movie version, Adaptation. Nobody knows why it's suddenly reappearing so regularly in the Corkscrew Swamp Sanctuary after a dozen years of absence, nor what strange qualities it might have if you actually ingested it.
