Dendrochilum tenellum is native to the Philippines, and grows in the mountains in the cloud forests.
There are some really amazing photos of them on-line, but the above is not one of them. (This one shows an amazing specimen, though.)
There's growing information here and here, and Hortus Botanicus sells them here. (Caveat emptor: I have no connection with HB, have never bought anything from them, and make no claims about their trustworthiness or the quality of their merchandise.) I doubt they're easy. If nothing else, the humidity requirements sound pretty extreme. But then, that's what you'd expect from a cloud forest plant.
