In June of 2017 I again participated in the annual Orchid Survey which is done each year in during June and July. Every Tuesday morning a team of Master Naturalists assembles at Cedar Ridge Preserve (south of Dallas) to locate, tag and catalog native orchid species.
The orchids in this area are all terrestrial. They grow in the soil near trees, and derive their nourishment from the vast network of fungi which exists underground. These orchids require the natural environment in order to grow. It is extremely difficult to replicate this environment in a greenhouse, and it should not be attempted.
Here are some photos of a recent survey:
