Chinese forget-me-not (original variety) is native to Yunnan, western Guizhou, southwestern to southeastern Xizang, western Sichuan and southern Gansu.
Chinese forget-me-not is also found in Bhutan. The type specimens were collected from Mengzi, Yunnan.
West Yunnan colored glaze grass (variety) produced in northwest Yunnan and southwest Sichuan.The type specimens were collected from Lijiang, Yunnan.
