When in active growth species prefers intermediate-warm conditions, bright diffused light, and should be kept drier in the winter. This is a “semi-hardy” cymbidium species, which means that it can tolerate cooler temperatures (down to high 30s or low 40s) in the winter, providing it is not allowed to be left cold and wet. In coastal California (San Francisco area south to San Diego) it will do well outside year round.

This species is also called the "Twisted Sepal Cymbidium". It has small ellipsoid to oval pseudobulbs. The flowers are scented, usually pale greenshish yellow or whitish, sometimes with purplish red markings. 

It occurs in south central China and Taiwan, where it is found in open forests, forest margins, grassy slopes and also rocky. shrubby slopes, with an elevation range of 800-2500 m.
