As the type species of Sinarundinaria, the close similarities between this and Fargesia spathacea show that Sinarundinaria is a synonym of Fargesia. Fargesia demissa is a short and beautiful variant, but it has not been given any new status within F. nitida.

This species is an important source of food for the giant panda.
