Buddleja davidii var. superba is endemic to the Yunnan province of western China.^[1] The taxonomy of the plant and the other five davidii varieties has been challenged in recent years. Leeuwenberg sank them all as synonyms, considering them to be within the natural variation of a species,^[2] a treatment adopted in the Flora of China published in 1996.^[3]
