Did you know there are wild orchids right here in Central Texas? Better yet, did you know that some orchids are mycoheterotrophs—meaning they rely on fungi for their nutrients rather than photosynthesis?
Join us for a guided walk to search for the rare and beautiful Glass Mountain Crested Coralroot (Bletia nitida, formerly known as Hexalectris nitida). This leafless orchid produces dense clusters of waxy, rose-brown flowers and is considered vulnerable throughout its range. In Texas, it is listed as a threatened species, making every sighting a special occasion.
What Makes This Orchid Extraordinary:
Mycoheterotrophic: It parasitizes fungi for its food rather than using photosynthesis
Weather-dependent: It only blooms in summers with abundant rain and humidity
Rarely displays: This orchid is self-pollinating and rarely produces fully open flowers
Geographically rare: While it may appear locally in Texas, it's considered vulnerable and may be extirpated in neighboring states
Walk Details:
Distance: Less than 2 miles
Terrain: Rocky with some slight inclines
What to bring: Smartphone or camera, water, closed-toe shoes suitable for rocky terrain
What to expect: A moderate nature walk through oak-juniper woodlands, searching for this elusive orchid and observing any mushrooms fruiting along the way
