Gastrochilus retrocallus is also known as Haraella retrocallus, but a rose by any other name .
I bought this last January bare root and in bud. I mounted it and it dropped its bud. Now it has rewarded me with 1 flower and another on the way. It is mounted on cork with some sphagnum around the roots. It gets misted daily and sometimes 2x a day in hot weather.
