Paphiopedilum armeniacum grows in a remote area of southwest China near Bijiang in western Yunnan Province. Plants are found on limestone hills and cliffs in forests above the Salween (Nujiang) River near the border with northeastern Burma at about 26.5°N Latitude. They grow at about 6550 ft. (2000 m) among rocks in semishady mountain forests. The nearest weather station is about 95 miles. (150 km) away. It is located above the same river valley at about the same elevation, so conditions should be essentially the same at the two locations.
