Underground Orchid

The Underground Orchid (Rhizanthella gardneri) is a rare and strange form of terrestrial orchid found in a few areas of Southwestern Australia. Like other members of its genus, Rhizanthella, it is a tuberous plant, lacking leaves and using a specially adapted stem to capture and store light for photosynthesis. This adaptation lets the plant thrive in a completely dark underground environment. The Underground Orchid lacks chlorophyll and instead makes use of a fungal partner to provide it with nutrients. It produces a solitary flower above ground every three years.
