Nice shooting yourself - I don't think I've ever seen that flower in the wild, either in Texas or here in Calif.
I just checked the distribution of pink lady slipper and it's pretty much entirely east of the Mississippi including Minnesota, but not in Florida. That suggests the plant prefers moist slightly acidic soil. It may be true of a number of the North American orchids as some rare ones are confined to acidic and boggy areas in southern New Jersey ("pine barrens") and North Carolina.
ADDENDUM: I just did a little more checking. There are only two orchids that grow in California, the California Lady Slipper (multiple white blossoms along the stem) which is only found in a few restricted high-altitude locations in northernmost California and adjacent Oregon, and the Mountain Lady Slipper (looks similar to the ubiquitous pink lady slipper in the image I posted, but it is white) which is only found at high altitude in the Sierras.
And as best I can determine, no orchids are native to Texas. Soils are probably too alkaline and also perhaps dry.
