I always thought Spathoglottis parsonii was just a variation of the plicata.
I have mine planted in large pots around a live oak tree. I leave them out all year long and they make it about half of the time. They are easy to find at the big box stores and not very expensive. I use lose loamy soil and patchy sun just like Elaine.
Other ground orchids that I have are cymbidiums, which are tougher than the Spathoglottis, bletillas, various jewel orchids and Arundina graminifolia, the bamboo orchid, shown here.
