Schoenorchis phitamii is an intermediate- to warm-growing native to Vietnam. This is a new species just accepted by Kew in 2019. Schoenorchis phitamii is very similar in stature to S. fragrans and S. tixieri, but the inflorescence is bigger. Still the plants are super minis, and just as cute as their nearest cousins. Grow similarly, too–make sure they dry out each day to prevent rot. All Schoenorchis (that I know of) are grown mounted.
Schoenorchis are used to being warm and bright, so they like to get wet and then dry out quickly (as would happen in a hot and breezy environment). My conditions are intermediate to warm, and I have had no problem growing Schoenorchis as long as I let them dry out. To promote quick drying, you should grow them mounted.
