I was so happy to see this post. I have been researching outdoor terrestrial orchids for my backyard. I have a Sobralia that is doing very well in light filtered through a palm tree; however, it was quite nerve racking putting an orchid in the ground.
The above Phauis link is great; I have had trouble finding any that were this useful. Vivienne are yours potted in your atrium or do you truly have one in the ground??
Does anyone out there have any growing in the ground in So Cal????
