Buddleja davidii var. alba is endemic to central and western China.[1] The plant has also been treated as a form, and a cultivar ('Alba').[2] However, Anthonius Leeuwenberg sank var. alba and the other five varieties of davidii as synonyms,[3] considering them to be within the natural variation of a species, a treatment also adopted in the Flora of China published in 1996,[4] and is also upheld by both the Plants of the World Online database and the International Dendrology Society's Trees and Shrubs Online website.[5][6]
Buddleja davidii var. alba is distinguished by its inflorescences of white flowers with yellow eyes, considered inferior to many of the white cultivars now in commerce, and narrower leaves.[2]
